Abstract:

This paper introduces two routes to produce liquefied natural gas from coke oven gas: cryogenic liquefaction route and methanation route.Comparison of these two routes shows that the better investment mode for now is to firstly establish a plant with cryogenic liquefaction route for the purpose,and then reconstruct a methanation plant on basis of the established cryogenic liquefaction plant when the catalytic synthesis reaction of methanation route proves to be mature and reliable.
