“…Production of liquefied natural gas (LNG) from landfill gas (LFG) has been one of the recent efforts to utilize the renewable energy and reduce the greenhouse gas [1][2][3][4]. Since the major components of LFG are methane (CH 4 : 50~70% by volume) and carbon dioxide (CO 2 : 20~40% by volume), CO 2 should be removed to avoid the serious increase of flow resistance or even a blockage of passage due to its deposition as solid or frost.…”

An integrated cryogenic system to separate carbon dioxide (CO 2 ) and produce LNG from landfill gas is investigated and designed. The main objective of this design is to eliminate the requirement of a standard CO 2 removal process in the liquefaction system such distillation or (temperature or pressure) swing adsorption, and to directly separate carbon dioxide as frost at the liquefying channel of methane. Two identical sets of heat exchangers are installed in parallel and switched alternatively with a time period so that one is in separation-liquefaction mode while the other is in CO 2 clean-up mode. A thermal regeneration scheme is presented for the purpose of saving energy and avoiding the stoppage of LNG production followed by the flow switching. The switching period is determined from results of a combined heat and mass transfer analysis on the CO 2 freeze-out process.
