A METHOD AND SYSTEM FOR CONTROLLING THE TEMPERATURE OF LIQUEFIED NATURAL GAS IN A LIQUEFACTION PROCESS

摘要

Disclosed herein is a method for controlling the temperature of a liquefied natural gas (LNG) produced from a chiller in a liquefaction process, the method comprising the step of varying the composition of a refrigerant stream in thermal communication with natural gas undergoing liquefaction in said chiller to thereby control the temperature of the LNG produced from the chiller.
