Heat exchanger with integrated liquid knockout drum for a system and method of cooling hot gas using a compressed refrigerant

摘要

A heat exchanger for cooling gas between compression stages using a compressed refrigerant. The heat exchanger has a pressure vessel with an integrated liquid knockout drum. A finned tube is contained within the pressure vessel. A gas passageway is defined as the volume between the finned tube and the pressure vessel. Refrigerant from a cooling circuit passes through the interior of the finned tube and cools the gas in the gas passageway. Condensate from the cooled gas is removed in the knockout drum. The heat exchangers may also be used in a triple pass cooler.

1. A heat exchanger for cooling gas and liquids between compression stages, said heat exchanger comprising:
a pressure vessel having a gas inlet located on a first end and a gas outlet located on a second end; a knockout drum perpendicular to the pressure vessel and in fluid communication with the pressure vessel; a finned tube with an interior, the finned tube located inside the pressure vessel and defining a gas passageway between the finned tube and the pressure vessel; a cooling circuit in fluid communication with the interior of the finned tube; a gas located in the gas passageway; and refrigerant located in the cooling circuit and the interior of the finned tube.
