The advantages of deep cold air separation

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...

The liquid air separation plant uses circulating nitrogen to absorb the cold end of LNG, thus replacing the traditional hot and cold end expanders of the liquid air separation plant. The liquid air separation plant energy consumption is reduced by using glycol aqueous solution closed circuit to absorb the cold at the high temperature end of LNG, thus replacing the traditional cool water tower with lower cooling water temperature and less water consumption. The key of the liquid air separation pl...
