Abstract:

H2 and methane gas are obtained through coke oven gas (COG) purification process.Methane is first compressed to compressed natural gas (CNG),and then further liquefied at -196℃ to liquefied natural gas (LNG).Through economic and technical analysis on the technology of H2 and LNG preparation by COG purification,it can be concluded that comprehensive use of COG is a new development direction.
