Abstract
A closed loop single mixed refrigerant process and system wherein the process efficiency is increased by increasing the temperature of liquefied material produced in a heat exchange refrigeration zone and thereafter cooling the liquefied material by flashing a portion of the liquefied material to produce a cooler liquefied material and a flash gas a portion of which is recycled to the heat exchange refrigerator. The process and system provide increased process efficiency and flexibility.
