UNDERWATER INSTALLATION AND PROCESS FOR COOLING A FLUID IN A HEAT EXCHANGER BY CIRCULATION OF SEA WATER.

摘要

The present invention relates to a method and an underwater plant for cooling (10) production fluid comprising the use of a heat exchanger (1) at the bottom of the sea (12), connected to transfer pipes. said production fluid (11a, 11b) comprising an external cooling circuit (2) capable of circulating cooling seawater, using a circulation pump (3), comprising: - supply devices (4, 4a) and discharge devices (5, 5a) of sea water from said external cooling circuit (2) and control and command devices (3a, 6-6a, 7- 7a) the variation of an identical flow rate (d2) of the discharge and the seawater supply.
