In this paper, a novel quadruple cycle for power generation is presented. It consists of a gas turbine cycle, a Brayton cycle of supercritical carbon dioxide, a Rankin organic cycle with a Cyclopentane working fluid, a Rankin steam cycle, a central tower, and a heliostat solar field. Because of improving the Brayton cycle's performance, supercritical carbon dioxide and the Rankine organic cycle have been added to the system. A solar tower system has been used to heat the incoming airflow to the combustion chamber. The heat generated by the solar tower in the first part increases the gas turbine cycle's air temperature, and in the second part, the water vapor heats the Rankin steam cycle. Due to solar radiation instability, the proposed system's performance is dynamically examined every hour of the year, and the results are reported. The thermodynamic simulation results are validated by Thermoflex software and reference case with high accuracy. In this regard, Energy, Exergy, Exergoeconomic, Exergoenvironmental, Emergoeconomic, and Emergoenvironmental (6E) analyses have been performed for this system. The result indicates that the gas turbine cycle's f fuel consumption is reduced by about 9% to 1.53 kg/s with the solar system's addition. Using solar energy and the Rankin steam cycle, the cycle's production capacity will increase from 43 MW to 66 MW.

Natural gas compressor stations have a significant potential for waste heat recovery. In this paper, a novel quadruple combined cycle has been proposed based on a turbocompressor gas station. In this regard, Serajeh gas station in Qom (Iran), including three 25 MW nominal gas turbines that each turbine provided power requirement for compressor, has been considered. Steam and organic Rankine cycles have been used to recover waste heat and generate more power, which uses exhaust gas turbines. Seven organic fluids have been examined. Energy, Exergy, Exergoeconomic, Exergoenvironment, Emergoeconomic, and Emergoenvironmental (6E) analyses have better understood the system from different perspectives. In this regard, computer code has been developed in MATLAB for 6E analysis. Verification of thermodynamic simulation of developed code has been compared with THERMOFLEX software and reference data with high accuracy. Also, sensitivity analysis was carried out based on main parameters. Advanced exergy-based analysis associated with endogenous/exogenous and avoidable/unavoidable parts has been performed for deep analysis of each component. The results show an increase of approximately 16% in the integrated cycle's thermal efficiency compared to gas turbines. The combustion chamber has the highest exergy destruction rate, and the LP superheater and economizer have the lowest exergy efficiency. R113 was selected as the best organic fluid from thermodynamic and R141b from an economic and environmental point of view. Cost rates and environmental impacts of the entire system will be approximately 3300 $ h−1 and 2038 pts h−1, respectively.

Installing solar collectors to preheat boiler feedwater is one of the most economical methods of repowering steam power plants. The production of freshwater in repowered plants can increase their productivity. The present study aimed at integrating the Bandar Abbas steam power plant's repowered cycles with desalination units and subsequently analyzing the cycles using the R-Curve tool. Three scenarios are were considered for repowering: In the first scenario, parallel collectors were used instead of the low-pressure feedwater heaters, while in the second and third scenarios, parallel solar collectors were used instead of low-pressure feedwater heaters integrated with multi-effect and multi-stage flash desalination units, respectively. The dynamic development of the R-Curve, as well as the use of a combination of artificial intelligence and genetic algorithm programming to optimize the complex cycles of the multi-generation of power, heat, and freshwater, are the most important issues presented in this study. Results show that the Bandar Abbas steam power plant in operation has an R-ratio equal to 1.21 and a cogeneration efficiency of 36.5 percent. In the first scenario of repowering, the R-ratio is equal to 1.21, and in most months, the cogeneration efficiency varies between 35 and 45 percent. In the second and third scenarios, however, cogeneration efficiency is 50 percent at its lowest level. Moreover, with the introduction of the new conceptual graphical curves, it was found that using more solar energy and adding desalination units increase the cogeneration efficiency throughout the year. Optimization of repowered cycles integrated with multi-effect and multi-stage flash desalination units increased freshwater production by 178 and 42 percent, respectively.

Using solar collectors to repower steam power plants is one of the cheapest methods to improve these power generation sites' technical, economic, and environmental performance. In this paper, using a comprehensive method based on economic benefits and environmental friendliness, solar collectors are designed to parallel with the feedwater heaters to repower the steam power plant. Also, an MSF desalination unit has been used to simultaneously generate power, heat, and freshwater in the repowered cycle due to the proximity of the studied steam power plant to the sea. Transient thermodynamic, exergy, economic, and environmental analyzes have been used to demonstrate performance improvements due to solar repowering. Results show that due to proper solar radiation at the site of the steam power plant, more use of solar collectors or solar factors equal to one lead to the highest economic benefits and the highest reduction in environmental impact. The solar collectors are also designed based on solar factors equal to one. The first scenario of repowering generates between 330 and 400 MW of power during the year. But in the second scenario, due to the consumption of the part of the cycle steam in the MSF unit, the amount of power generation in most months is about 310 MW. In the first and second scenarios of repowering compared to the base steam power plant, the total cost is reduced by an average of 50% and 41%, respectively. The total environmental impacts in the first and second scenarios of the repowering have been reduced by 30% and 22%, respectively, about the steam cycle. The mass flow of freshwater produced in this unit will be 115.4 kg/s. The performance ratio of the MSF unit will be 8.8, and the gain output ratio will be 9.62. The price of freshwater produced in this unit will be $0.21 per cubic meter of desalinated water.

Site utility, without a doubt, is one of the major units in process industries that consumed a lot of fossil fuels and significantly emitted emission pollution. In this paper, a systematic procedure was proposed to optimize the utility system's design and integration based on a targeting approach as process integration technique, exergetic, exergoeconomic, exergoenvironmental analysis associated with life cycle assessment (LCA), and multi-objective optimization through water cycle and genetic algorithms. Total site analysis was performed to provide an essential understanding of the equipment's characteristics and interactions in the site utility system. It also aims for power production and the temperature of the boiler and each steam level with acceptable accuracy. Furthermore, the exergetic, exergoeconomic, and exergoenvironmental analyses were presented to declare the effects of irreversibility, economic, and environmental impacts on the system. In this paper, to show the proposed method's applicability, the optimal design of a site utility associated with a petrochemical complex has been considered. First, the optimal design is performed based on minimization of total annualized costs (TAC) as one-objective function through star software, genetic algorithm (GA), water cycle algorithm (WCA), proposed GA, and proposed WCA method. In the next phase, the optimal design is done based on MOGA, MOWCA, proposed MOGA, and proposed MOWCA methods based on maximum exergetic efficiency, and freshwater production, and minimization of exergetic cost, and total environmental exergetic impact. Results show by using the new procedure, the optimum solution has been achieved by a significant reduction of computational time.

A novel MED-based desalination system for low-grade heat sources with a temperature between 65 °C and 90 °C has been proposed. Low-grade heat-driven desalination systems are of the most important methods for increasing energy efficiency and assisting the environment along with alleviating the water scarcity problem. The new proposed system is known as cascade multi-effect distillation (CMED). It is designed based on multi-step heat extraction from the heat source fluid (HSF). Multi-step heat absorption helps to form two arrays of MED effects and to utilize two boosters to achieve better performance. The advantage of this system is less complexity (for example, lower vapor injection), and improved performance along with reduced electricity consumption in comparison with the most recent MED-based configurations, including flash boosted MED (FB-MED) and distributed boosted MED (DBMED). The results show that the CMED’s production rate is increased on average by 15.5% compared to FB-MED, and up to 7.3% relative to DBMED. The normalized pumping power consumption (NPPC) is dropped by 14.5% and 11.5% on average compared to FB-MED and DBMED, respectively. Also, the specific capital cost is reduced by about 1.15% and 0.80% on average.

The use of solar energy to preheat natural gas before a city gate station (CGS) for reducing fuel consumption and environmental emissions is investigated in a real CGS. All analyses are conducted with a 1-h time-step throughout the entire year so that seasonal climate changes are accounted for precisely. A thermodynamic analysis of the hybrid system is performed with TRNSYS and verified with THERMOFLEX so as to ensure reliability. In addition, dynamic exergetic, exergoeconomic, and exergoenvironmental analyses for the proposed system are carried out. A life cycle assessment (LCA) based on Eco-indicator 99 is performed using SIMA PRO to compute the environmental impacts for each component of the system. The exergetic, exergoeconomic, and environmental analyses are performed in Engineering Equation Solver (EES) software. To perform the transient exergetic, exergoeconomic, and environmental analyses, the results of the thermodynamic analysis from TRNSYS are automatically imported into the EES code. The advanced exergetic, exergoeconomic, and exergoenvironmental analyses are performed to better determine components that have high potentials for improving the system; potentials are considered based on the exergy destruction, exergetic cost of destruction, and environmental impacts associated with exergy destruction.

Reliable production of freshwater and energy is vital for tackling two of the most critical issues the world is facing today: climate change and sustainable development. In this light, a comprehensive review is performed on the foremost renewable energy-driven polygeneration systems for freshwater production using thermal and membrane desalination. Thus, this review is designed to outline the latest developments on integrated polygeneration and desalination systems based on multi-stage flash (MSF), multi-effect distillation (MED), humidification-dehumidification (HDH), and reverse osmosis (RO) technologies. Special attention is paid to innovative approaches for modelling, design, simulation, and optimization to improve energy, exergy, and thermo-economic performance of decentralized polygeneration plants accounting for electricity, space heating and cooling, domestic hot water, and freshwater production, among others. Different integrated renewable energy-driven polygeneration and desalination systems are investigated, including those assisted by solar, biomass, geothermal, ocean, wind, and hybrid renewable energy sources. In addition, recent literature applying energy, exergy, exergoeconomic, and exergoenvironmental analysis is reviewed to establish a comparison between a range of integrated renewable-driven polygeneration and desalination systems.

The present paper simulates and dynamically analyzes a combined heat and power (CHP) system driven by a gas-fueled internal combustion engine. The CHP system uses a heat exchanger to convert the heat loss of the engine to meet heat demand and uses a generator for power generation. Then, the impact of the use or non-use thermal energy storage (TES) is examined on power and heat generation. Given the different demands of different seasons, two smart control strategies are developed concerning time to attain higher efficiency in different seasons. A TES is included in the control strategy for cold and hot seasons, and analyses are performed for a typical week. The gas engine of the CHP system uses time and temperature variables simultaneously to operate smartly by two strategies for a year instead of one single strategy. The results show that when a control strategy with variable partial loads based on temperature and time is employed, the efficiency of the CHP system’s gas engine is improved. Using the results of the new and smart control strategy, the CHP system exhibits an efficiency of 84.2% in the hot season and an efficiency of 87.0% in the cold seasons for a typical week.

The generation of the electric power through magnetohydrodynamic (MHD) is one of the most advanced high-temperature energy conversions as it directly turns the heat into electricity. In this study, a quadruple cycle with a MHD generator was considered as the upstream cycle, a Brayton cycle was taken as the middle cycle through heating, and an organic Rankine cycle and steam cycle were regarded as the downstream cycles using the heat loss of the MHD generator and gas turbine, respectively. Energy, exergy, exergoeconomic, exergoenvironmental, emergoeconomic, and emergoenvironmental (6E) analyses were done in the proposed system simultaneously for the first time. In addition, advanced exergy, exergoeconomic, and exergoenvironmental analyses were performed for the proposed system to show the effect of irreversibility accurately and deeply. Despite the slight difference between the results of the emergoeconomic and emergoenvironmental sector with the exergoeconomic and exergoenvironmental sector, the obtained qualitative results were very similar showing that the emergoeconomic and emergoenvironmental analyses can be proper alternatives to the conventional exergoeconomic and exergoenvironmental analyses. The temperature of the heat source is one of the most important criteria for fluid selection in the organic Rankine cycles. Five organic fluids were selected and evaluated according to the desired hot source temperature for the Rankine organic cycle (262 °C). The results showed that the R141b with energy and efficiency of 15.25 and 58.05%, respectively, had the best thermodynamic and exergy performance with the least amount of total costs using this fluid.

The ever-increasing world population, change in lifestyle, and limited natural water and energy resources have made industrial seawater desalination plants the leading contenders for cost-efficient freshwater production. In this study, the integration of a combined cycle power plant (CCPP) with multi-effect distillation (MED) and reverse osmosis (RO) desalination units is investigated through comprehensive conventional and advanced exergy, exergoeconomic, and exergoenvironmental analyses. Firstly, the thermodynamic modelling of the CCPP is performed by using a mathematical programming procedure. Then, a mathematical model is developed for the integration of the existing CCPP plant with MED and RO desalination units. Finally, conventional and advanced exergy, exergoeconomic, and exergoenvironmental analyses are carried out to assess the main performance parameters of the integrated CCPP and MED-RO desalination system, as well as to identify potential technical, economic, and environmental improvements. A case study is presented based on the Shahid Salimi Neka power plant located at the north of Iran along the Caspian Sea. The mathematical modelling approach for the integrated CCPP and MED-RO desalination system is solved in MATLAB, and the results are validated via Thermoflex software. The results reveal an increase of 3.79% in fuel consumption after the integration of the CCPP with the desalination units. The exergy efficiency of the integrated system is 42.7%, and the highest cost of exergy destruction of the combustion chamber is 1.09 US$ per second. Economic and environmental analyses of the integrated system also show that gas turbines present the highest investment cost of 0.047 US$ per second. At the same time, MED exhibits the highest environmental impact rate of 0.025 points per second.

In this paper, the simultaneous production of power and freshwater by the integration of a gas turbine (GT), a supercritical carbon dioxide (S-CO2) cycle, an organic Rankine cycle (ORC) and a reverse osmosis (RO) desalination unit is proposed. The S-CO2 and the ORC are bottoming cycles that recover the waste heat from the exhaust gases of the GT. A RO seawater desalination unit has been added to this power generation cycle to produce low-cost freshwater. The thermodynamic modelling and the simulation of the integrated cycle are performed. In addition, exergetic, exergoeconomic and exergoenvironmental analyses have been carried out. Cyclopentane has been chosen as working fluid of the ORC. The results show that the total energy generated by the cycles is about 75.1 MW; the compressors and pumps consume 44% and the rest is sent to the electricity grid. The integration of the S-CO2 cycle with the gas turbine increases the total efficiency by 10.9%. Also, the addition of the ORC to this integration, improves the efficiency by about 2%. The cost of power generation in the gas turbine is about 0.604 $/s, in the turbine of the S-CO2 cycle about 0.182 $/s and in the turbine of ORC cycle about 0.036 $/s. The cost of freshwater production in the RO unit with 5 MW of power consumption is 0.88 $/m3. The results show that the proposed combined GT/S-CO2/ORC/RO regenerative system is promising in terms of waste heat recovery from gas turbines. As advantages, deep waste heat recovery, high exergetic efficiency, and low power and freshwater costs have been achieved.

In the recent years, considering aridity problem of the country and high potential of desalinating the seawater in the southern and northern coasts, focusing on the poly-generation cycles of power and distillate with the lowest possible cost and emission of the pollutants has been increased. In this research, the study of the trigeneration system of power, heat and desal water located in the Qeshm island has been conducted. The potentials of the existing unit have been evaluated and the different scenarios have been proposed to improve the performance of the system. Setting the inlet air cooling system up to the gas cycle is one of the schemes proposed to diminish the undesirable effects of the ambient conditions. Also integrating the existing MED desalination unit with RO system and using solar thermal collector field in order to improve the performance of the system and to propose the optimal scheme for the operating unit has been investigated. The conventional and the advanced exergy, exergo-economic and exergo-environmental analyzes based on life cycle assessment have been used to evaluate the existing and the proposed systems. The multi objective optimization process has been performed to maximize the exergetic efficiency and to minimize the cost and environmental impact of the product of the system. Considering the complexity of the problem, using the genetic programming to generate the objective functions has been conducted. In order to apply the optimization process on the existing and the proposed system, multi objective genetic algorithm (MOGA) and multi objective water cycle algorithm (MOWCA) have been used. Multi objective water cycle algorithm has been performed for the first time at the energy problems in this research. The results shows that using the inlet air cooling system has decreased the fuel consumption, total costs and environmental impacts of the system by 1019 tons/year, 914 k$/year and 197 kpts/year, respectively. Also integrating the existing unit with the solar thermal collector field to achieve an increase of 4.77% in efficiency of the system has been investigated. Five different types of STC at two configurations have been evaluated and the thermodynamic, economic and environmental optimal solution has led to calculate 9081 m2 area of required collectors. Using RO desalination unit in the downstream of MED has prevented the energy leakage and increased the distillate production rate by 255.12 tons/h. The optimization processes using two methods shows the capability of the MOWCA and lead to an increase of 12.66% in exergetic efficiency and decreased the total cost and environmental impact rate of the system by 47.4$/h and 49.2pts/h, respectively.

Today, as fossil fuels are depleted, renewable energy must be used to meet the needs of human beings. One of the renewable energy sources is undoubtedly the solar–geothermal power plant. In this paper, the conventional and advanced, exergo-environmental and exergo-economic analysis of a geothermal–solar hybrid power plant (SGHPP) based on an organic Rankin cycle (ORC) cycle is investigated. In this regard, at first, a conventional analysis was conducted on a standalone geothermal cycle (first mode), as well as a hybrid solar–geothermal cycle (second mode). The results of exergy destruction for simulating the standalone geothermal cycle showed that the ORC turbine with 1050 kW had the highest exergy destruction that was 38% of the total share of destruction. Then, the ORC condenser with 26% of the total share of exergy destruction was in second place. In the hybrid geothermal–solar cycle, the solar panel had the highest environmental impact and about 56% of the total share of exergy destruction. The ORC turbine had about 9% of all exergy destruction. The results of the advanced analysis of exergy in the standalone geothermal cycle showed that the avoidable exergy destruction of the condenser was the highest. In the hybrid geothermal–solar cycle, the solar panel, steam economizer and steam evaporator were ranked first to third from an avoidable exergy destruction perspective. The avoidable exergo-economic destruction of the evaporator and pump were higher than the other components. The hybrid geothermal–solar cycle, steam economizer, solar pane and steam evaporator were ranked first to third, respectively, and they could be modified. The avoidable exergo-environmental destruction of the ORC turbine and the ORC pump were the highest, respectively. In the hybrid geothermal–solar cycle, steam economizers, solar panel and steam evaporators had the highest avoidable exergy destruction, respectively. For the standalone geothermal cycle, the total endogenous exergy destruction and exogenous exergy destruction was 83.61% and 16.39%. Moreover, from an exergo-economic perspective, 89% of the total destruction rate was endogenous and 11% was exogenous. From an exergo-environmental perspective, 88.73% of the destruction rate was endogenous and 11.27% was exogenous. For the hybrid geothermal–solar cycle, the total endogenous and exogenous exergy destruction was 75.08% and 24.92%, respectively. Moreover, 81.82% of the exergo-economic destruction rate was endogenous and 18.82% was exogenous. From an exergo-environmental perspective, 81.19% of the exergy destruction was endogenous and 18.81% was exogenous.

In this paper, thermodynamic simulation and analyses of cascade refrigeration and heat recovery cascade refrigeration cycles are investigated. Due to the high heat dissipation in the gas cooler in the cascade refrigeration cycle, the heat recovery cascade refrigeration cycle uses this heat to launch a Rankine cycle. R744 refrigerant for the high-temperature circuit and R744A refrigerant for the low-temperature circuit are used. Energy, exergy analyses for these cycles have been performed. Due to the better performance of the heat recovery cascade refrigeration system, advanced exergy, exergoeconomic, and exergoenvironmental, analyses have been performed for this cycle with Engineering Approach. In this regard, computer code was developed to compute these analyses. Multi-objective optimization of the cycle by the genetic algorithm has been performed with the objective functions of exergy efficiency and total product cost as well as the coefficient of performance and product environmental impact. Exergoeconomic analysis demonstrates that the product cost rate for the cycle is 3.4 $.h-1. Based on exergoenvironmental analysis, the compressor1 has the highest environmental impact. The optimization results reveal that using the heat recovery cascade refrigeration cycle leads to an increasing 7.6% coefficient of performance and 12.5% exergy efficiency.

In this study, an optimal design and analysis of an integrated internal reforming Solid Oxide fuel cell (IRSOFC) - Gas Turbine (GT) – Organic Rankine Cycle (ORC) system are investigated. R407C and R404A as ORC working fluids are used to produce the additional power based on the recovery of the flue gases in the ORC. A thermodynamic simulation of the integrated system has been performed to evaluate the performance of the proposed cycle. In this regard, exergetic, exergoeconomic and exergoenvironmental analyses have been done for a better understanding of the interaction between the components and the overall system. In order to carry out the exergoenvironmental analysis, the environmental impacts obtained by Life Cycle Assessment (LCA) are apportioned to the exergy streams. The analysis of this integrated system has been carried out by using computer code in MATLAB. A Multi-Objective Water Cycle Algorithm based on the maximization of overall exergy efficiency and minimization of total exergetic cost rate and total exergetic environmental impacts was performed to find optimum design variables for the proposed system. The results show that R407C has the best thermodynamic performance and with this organic fluid the overall energy and exergy efficiencies for the proposed optimum system are 49.42% and 46.83% respectively. Furthermore, the exergoeconomic and exergoenvironmental main optimum parameters are comprised and evaluated.

Biogas is the gas produced by the anaerobic degradation of organic matter. In addition to the usual uses in burning, it has widespread applications as a raw material in some industries. The biomass of organic matter decomposition is a good fertilizer for agriculture. Unfortunately, despite such a large potential for reasons such as the cheapness of energy in Iran, the use of this benefical capacity has not been addressed so far. This paper investigates the potential of biogas production from poultry manure sources in Iran and demonstrates the examples of biogas plants in Iran. Also, the information about the capacity of biogas production has been investigated and reported in different provinces in Iran. The results consist of economic analysis as the cost of biogas production, and the environmental analysis as the environmental impact of the biogas production and carbon footprint. Kermanshah, Chaharmahalbakhtiari, Golestan, Bushehr and North Khorasan provinces have the highest capacity for biogas production from poultry manure. The highest cost savings by using the biogas are in Khorasan Razavi and Isfahan provinces and the lowest levels have been found in Ardebil and North Khorasan provinces.

In this paper, full repowering of a 320 MW steam power plant was investigated in Bandar Abbas. Due to unavailability of natural gas in the winter, LNG, Diesel, and Heavy fuel were examined as alternative fuels. The energetic, exergetic, exergoeconomic, and exergoenvironmental (4E) analyses were performed for old and repowered cases. The exergoenvironmental analyses were done based on the Life Cycle Assessment in SimaPro software. The net power, fuel consumption, costs, and environmental impacts were calculated by considering different fuels for each season. To better demonstrate the plant performance, the exergy destruction level (EDL) and the exergy cost destruction level (ECDL) were defined and applied as EDL/ECDL. To perform this analysis, a computer program was developed that could predict the base cycle and repowered cycle behaviors for different operating conditions with relative errors of less than 1.85%. Results demonstrated a 16% increase in the overall cycle efficiency, a 12% decrease in the methane consumption, and a 3% elevation in the net power using the LNG fuel.

Biomass gasification for the production of clean energy and clean technology is a practical alternative to fossil fuels. In this paper, for the first time, a biomass Integrated Gasification Combined Cycle (IGCC) based on olive pits as fuel is investigated by conventional and advanced exergy, exergoeconomic and exergoenvironmental analyses (4E). Environmental impacts, availability, and interest in using olive pits as newly utilized renewable biomass sources have been considered in the present study. With conventional exergy analysis, the primary causes of entropy generation, exergy cost of destruction, and exergoenvironmental impacts in the plant can be indicated. Also, with advanced analysis, the real potential can be determined for improving the system as well as equipment interactions. The exerg environmental analysis has been performed based on Life Cycle Assessment and Eco indicator 99. In this regard, the LCA analysis based on Eco indicator 99 has been done by SIMA Pro software. Furthermore, computer code has been developed for thermodynamic simulation and conventional and advanced 4E analyses of the proposed system. It can predict the plant behavior for different operating conditions with relative errors of less than 2.5% with Thermoflex software. Results show the conventional and advanced 4E analyses and evaluation for considered biomass IGCC systems simultaneously. By the exergetic analysis, the location, values, and sources of entropy generation in the system are identified. By exergoeconomic analysis, the information about the cost in the components has been indicated in terms not only of capital investment but also of the cost of exergy. Through the exergoenvironmental analyses, it can be concluded that improving the efficiency and decreasing fossil fuel consumption are the key factors of promoting environmental characteristics. Splitting the exergy destruction, the capital investment cost, and the component-related environmental impact related to each component into endogenous/exogenous and avoidable/unavoidable parts promotes these analyses and enhances the quality of the conclusions achieved from them.
