Abstract (en)
[origin: US2017350648A1] A process for producing liquefied natural gas and liquid carbon dioxide comprising: Step a): separating a natural gas feed gas into a CO2-enriched gas stream and a CO2-depleted natural gas stream; Step b): liquefying the CO2-depleted natural gas stream in a liquefaction unit comprising at least a main heat exchanger and a system for producing frigories, said liquefaction unit comprising at least one refrigeration cycle fed by a refrigerant stream; Step c): simultaneous liquefying of the CO2-enriched gas stream resulting from step a) in a CO2 liquefaction unit; wherein the refrigeration necessary for the liquefaction of the CO2-enriched gas stream and for the liquefaction of the natural gas is supplied by said frigorie-producing system of the liquefaction unit and in that the refrigeration necessary for the liquefaction of the CO2-enriched gas stream originates from a portion of said refrigerant stream supplying the refrigeration cycle of said liquefaction unit.
