Title:
METHOD AND APPARATUS FOR TREATING A HYDROCARBON STREAM AND METHOD OF COOLING A HYDROCARBON STREAM
Document Type and Number:
WIPO Patent Application WO/2010/012560
Kind Code:
A3
Abstract:
Method and apparatus for treating a mixed hydrocarbon feed stream (10), such as a natural gas stream. The mixed hydrocarbon feed stream (10) is expanded into a mixed-phase hydrocarbon stream (20), which is separated the to provide at least a light overhead stream (30) and a heavy bottom stream (50). The light overhead stream (30) is compressed in one or more first compressors (16) to provide one or more first compressed light streams (40) and further compressed in one or more second compressors (22) to provide one or more further compressed light streams (60). One or more first compressor recycle lines (42) extend around the or each first compressor (16), and one or more second compressor recycle lines (32) having one or more in-line coolers (34) extend around the or each second compressor (22). The method and apparatus may be used in a method of cooling an initial hydrocarbon stream (100).
