Title:

METHOD FOR TREATING A MULTI-PHASE HYDROCARBON STREAM AND AN APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2011/009832

Kind Code:

A3

Abstract:

A multi-phase hydrocarbon stream (145) is treated to provide a treated liquid hydrocarbon stream (165), such as a liquefied natural gas (LNG) stream. The multi-phase hydrocarbon stream (145) is passed to a first gas/liquid separator (150), wherein it is separated at a first pressure to provide a first separator hydrocarbon vapour stream (205) and a first separator bottoms stream (155). The first separator bottoms stream (155) is then separated in a second gas/liquid separator (160) at a second pressure that is lower than the first pressure, to provide a second separator hydrocarbon vapour stream (175) and a treated liquid hydrocarbon stream (165). The second separator hydrocarbon vapour stream (175) is compressed in an overhead stream compressor (180) to provide a stripping vapour stream (185) which is passed to the first gas/liquid separator (150).
