Abstract
An energy study has been conducted on the process of making sulphuric acid (in two ways: by one-stage and two-stage conversion) and the process of making sulphur from SO2-containing gases resulting from the pyrometallurgical production of copper. The exergy method of thermodynamic analysis has been used as a method of investigation. The general and relative exergy characteristics of the processes have been determined. The results of the investigation show higher exergy efficiency of the processes of making sulphuric acid (in both ways) than that of the process of making sulphur from SO2-containing metallurgy gases.
