METHOD AND APPARATUS FOR SEPARATING AND RECOVERING LIQUID COMPONENTS FROM THE EFFLUENT FROM A NATURAL GAS PIPELINE CONTAINING BOTH GASEOUS AND LIQUID COMPONENTS

摘要

Liquids in natural gas pipelines are separated, accumulated and distributed in a system wherein the pipeline contents are introduced into a vertical separation zone, the separated gaseous components are withdrawn from the upper portion of the separation zone and reintroduced into the pipeline at a downstream point, a stream of liquid components is withdrawn from a bottom portion of the separation zone, excess liquid components are introduced into an accumulation zone having a gradually rising slope and extending from the bottom portion of the separation zone to the upper portion of the separation zone, and gas displaced by and disengaged from the liquid in the accumulation zone is introduced into the upper portion of the separation zone, while the liquid is withdrawn and removed at a predetermined rate.
