We are working on different aspects of the Energy and Water Integration System by using cogeneration approaches that involve systems with renewable energy. Recently, we started to work on the integration of the above-mentioned issues with environmental (carbon trade) and agricultural (nexus) matters (clean technologies). We take advantage of various analyses, such as pinch technology, exergy analysis, and constructional theory to achieve our goals. We are involved in many projects to improve energy and water consumption in the oil & gas industry.
