SUBSEA HEAT EXCHANGER, CLEANING TOOL AND APPURTENANT METHOD

摘要

Subsea heat exchanger (1) cooling a hydrocarbon-containing fluid by flowing seawater through it. Cooling pipes (4) are arranged in a convection section (11). The heat exchanger has an inlet (5a) and an outlet (5b) for the hydrocarbon-containing fluid, and an inlet (21) and outlet (22) for seawater. The seawater inlet (21) is connected to the cooling pipes (4). The inlet (5a) and the outlet (5b) of the hydrocarbon-containing fluid are connected to the convection section (11). The seawater can flow through the cooling pipes (4) and the hydrocarbon-containing fluid can flow in the convection section (11) in contact with the outer walls of the cooling pipes (4). The heat exchanger comprises also a cap (6) at at least one end of the cooling pipes (4), wherein the cap (6) comprises one or more receiving arrangements (8) for anodes (7) and/or one or more anodes (7).

主权项

1. A subsea heat exchanger adapted for cooling of a hydrocarbon-containing fluid by through-flow of surrounding seawater through the subsea heat exchanger, the subsea heat exchanger comprising:
a plurality of cooling pipes arranged in a convection section, which heat exchanger has an inlet and an outlet for the hydrocarbon-containing fluid, as well as an inlet and an outlet for the seawater, wherein: the inlet for the seawater is connected to the cooling pipes; and the inlet and outlet for the hydrocarbon-containing fluid is connected to the convection section; so that the seawater can flow through the cooling pipes and the hydrocarbon-containing fluid can flow through the convection section in contact with the outer walls of the cooling pipes, wherein the subsea heat exchanger further comprises a cap at at least one end of the cooling pipes, wherein the cap comprises one or more receiving arrangements for anodes and/or one or more anodes.
