In distilleries during the process of fermentation, huge quantity of Carbon dioxide (CO2) gas is evolved. Carbon dioxide gas has wide ranging applications in Food, Pharma, Steel and allied industries. The Carbon dioxide which evolved has a foul odor hence it undergoes a process whereby it is passed through Sodium permanganate solution to render it odourless and pure from undesirable constituents. The pure CO2 gas thus obtained is ready for use in various applications.
