First Claim
Patent Images
1. A subsea apparatus for processing a well stream, the apparatus comprising:
- a separator arranged to separate, at least partly, liquid and gas contained in the well stream to produce separated liquid and gas;
a cooler positioned downstream of said separator and arranged to cool said separated gas to produce cooled gas; and
a mixing point positioned downstream of said cooler and arranged to combine said cooled gas with said separated liquid to form a wet gas for supply to a compressor provided downstream from said mixing point.

Abstract
Subsea apparatus (10) for processing a well stream (2) and a method of processing a well stream subsea is described. In an embodiment, liquid (5) and gas (3) contained in the well stream (2) is separated. The separated gas (3) is cooled and the cooled gas (32) is combined with the separated liquid (5) to form a wet gas (52) for a compressor (90). An active cooling arrangement (30) may be used in one example to enhance the cooling effect provided by the cooler (30). Advantageously, the apparatus (10) can be arranged compactly, and may be provided on a subsea retrievable module.

19. A method of processing a well stream subsea, comprising the steps of:
-
separating, at least partly, liquid and gas contained in the well stream to produce separated liquid and gas; after performing said separating step, cooling said separated gas to produce cooled gas; and combining said cooled gas with said separated liquid to form a wet gas for a compressor. - View Dependent Claims (20, 21)
