Abstract
Liquid mixed refrigerant is flashed in a vapor-liquid separator from which a portion of the liquid is pumped to an evaporator. The liquid refrigerant boils and partially vaporizes in the evaporator, thereby cooling a process stream. Partially vaporized refrigerant is returned to the separator for separation of vapor from liquid. Separator vapor is countercurrently contacted with a further portion of the separator liquid in a packed section in the upper part of the separator to assure that exiting vapor passing to recompression is saturated with the heavier refrigerant component(s).
