  • Method and system for producing a liquefied natural gas product
    Patent number: 12710225
    Abstract: A method for producing liquefied natural gas (LNG), wherein a feed natural gas (NG) containing methane and higher hydrocarbons, including benzene, is cooled to a first temperature level in a first cooling step using a first mixed refrigerant (WMR) and is subsequently subjected to counter-current absorption using an absorption liquid, wherein a gas fraction depleted in the higher hydrocarbons is formed, at least a portion of the gas fraction is cooled to a second temperature level in a second cooling step using a second mixed refrigerant (CMR) and is liquefied to form the liquefied natural gas (LNG), characterized in that the absorption liquid is formed from another portion of the gas fraction, which portion preferably condenses above the counter-current absorption and is returned to the counter-current absorption, in particular without a pump.
