METHOD FOR SELECTIVE EXTRACTION OF NATURAL GAS LIQUIDS FROM RICH NATURAL GAS

摘要

A method for selective extraction of natural gas liquids from "rich" natural gas. The method involves the step of effecting a heat exchange between a rich natural gas stream and a refrigerant fluid to lower a temperature of the rich natural gas stream. The heat exchange is controlled to lower the temperature of the rich natural gas stream to a selected hydrocarbon dew point in order to condense at least one selected hydrocarbon liquids carried in the rich natural gas stream.
