This study determines and presents the capital and operating costs imposed by the use of CO₂ capture technologies in the refining and petrochemical sectors. Depending on the refining process and the CO₂ capture method, CO₂ emissions costs of EUR 30 to 40 per ton of CO₂ can be avoided. Advanced low-temperature CO₂ capture technologies for upgrading oxyfuel reformers may not provide any significant long-term and short-term benefits compared to conventional technologies. For this reason, an analysis was performed to estimate the CO₂ reduction potential for the oil and gas industries using short- and long-term ST/MT technologies, was arriving at a reduction potential of about 0.5–1 Gt/yr. The low cost of CO₂ reduction is a result of the good integration of CO₂ capture into the oil production process. The results show that advanced gasoline fraction recovery with integrated CO₂ capture can reduce the cost of producing petroleum products and reduce CO₂ emissions, while partial CO₂ capture has comparative advantages in some cases.

This paper examines a multistep physicochemical process underlying the recycling of spent cobalt-containing current sources, which comprises an opening step in a shredder, secondary comminution in a rotor knife mill, and mechanical comminution of electrode materials in a ball mill, followed by chemical leaching and extraction, and allows the yield of cobalt compounds to be raised. In describing the combination of mechanical comminution and chemical leaching processes, we rely on results of studies of mechanochemical decomposition processes in the case of alkali metals [1]. To analyze the influence of a combination of mechanical and technological factors on the effectiveness of the preparation of required products, we derive governing dimensionless criteria and criterial relations using similarity and dimension theory methods.
