ABSTRACT:
A process and system for removing condensable vapors contained within the gas stream in accordance with the process and system, condensable vapors contained within the gas stream are condensed within one or more condensers through indirect heat exchange of the gas stream with a refrigerant stream. This produces a refrigerated gas stream and a heated refrigerant gas stream. Further heat is exchanged from at least part of the heated refrigerant stream to the refrigerated gas stream and in economizing heat exchanger to form a cooled refrigerant stream from the heated refrigerant stream. The refrigeration stream is produced by combining a cryogenic stream with the at least part of the cooled refrigerant stream in a mixing chamber of an ejector or analogous equipment.
