Title:
NATURAL GAS LIQUEFACTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2011/136543
Kind Code:
A2
Abstract:
The present invention relates to a natural gas liquefaction process which is simple because of comprising one freezing cycle, thereby enabling compactness of a system and easy operation of a liquefaction system, and has excellent natural gas liquefaction efficiency by precisely separating a refrigerant into a heavy key portion and a light key portion in the required composition through a separation means, precooling natural gas with one refrigerant flow in a first heat exchange area, and liquefying natural gas with the other refrigerant flow in a second heat exchange area.
