NATURAL GAS LIQUIDS RECOVERY DEVICE AND METHOD

摘要

A natural gas liquids (NGL) recovery system and method for separating NGLs from a feed gas is provided. The method includes receiving the feed gas; increasing a pressure of the feed gas by running the feed gas through a compressor connected to a gas turbine; diverting part of the feed gas from an output of the compressor and feeding the diverted part to a dryer; drying the diverted part to remove water and produce a dry gas; expanding the dry gas in a turbo-expander; separating the expanded gas into the NGL and fuel gas; and providing the fuel gas to the gas turbine as fuel without contamination.
