Liquefaction provides an efficient approach for better recovery and utilization of CBM(coal bed methane).For CBM with low methane content
methane enrichment has to be considered along with liquefaction
so the liquefaction technology is different from that for the ordinary natural gas.There are mainly two solutions for the liquefaction of CBM with low methane content: one is liquefaction at first and then concentrate methane via a distillation process;the other one is adopting an adsorption process firstly t...
