PASSIVE LOW PRESSURE FLASH GAS COMPRESSION SYSTEM

摘要

A subsea passive flash gas compression system that includes a first separator (16) that removes high pressure flash gas from a hydrocarbon product, a second separator (18) that removes low pressure flash gas from the hydrocarbon product after the high pressure flash gas has been removed, and an ejector (14). The ejector (14) includes a high pressure input that is coupled to a high pressure flash gas output (26) of the first separator. The ejector also includes a low pressure input that is coupled to a low pressure flash gas output (28) of the second separator. An output of the ejector is coupled to an outlet pipeline that extends from proximate the sea bottom to the sea surface.
