Abstract
A subsea heat exchanger for cooling or heating a hydrocarbon-containing fluid includes a convection section enclosed by a shell or enclosure comprising, one or more heat exchanging fluid inlet(s) and outlet(s), one or more hydrocarbon-containing fluid inlet(s) and outlet(s), and one or more fluid carrying convection tube(s) adapted for heat transfer between the hydrocarbon-containing fluid on the inside of the tube(s) and a surrounding heat exchanging fluid on the opposite side of the tube(s). The heat exchanger also includes one or more flow regulating device(s) for controlling the hydrocarbon-containing fluid outlet temperature. The heat exchanging fluid circulates in a closed circuit for heat transfer both with said hydrocarbon-containing fluid and with surrounding sea water on the outside of the enclosure.
