What are the types of distillation columns for producing pure oxygen and pure nitrogen products

Biogas purification is the removal of impurity components from biogas to make high quality CH4 with high methane content, calorific value and impurity gas components that meet the requirements of natural gas standards. The biogas produced by the anaerobic fermentation process contains approximately 55% CH4 and 45% CO2, as well as small amounts of H2S, H2O and other gaseous components, which can be increased to over 95% by separation and purificat...
