▎ 摘　　要

NOVELTY - The heat exchange system has a heat exchanger which is selected from a shell and tube heat exchanger or a plate and frame heat exchanger. A graphene oxide membrane (102) is joined to the porous support within the heat exchanger. The layers have an interlayer spacing of between about 0.7 nm and 1.1 nm. The heat exchanger is configured to receive a first heat exchange fluid stream at a first temperature flowing in contact with a first side and a second heat exchange fluid stream at a second temperature flowing in contact with a second side. The heat exchanger receives a first heat exchanger fluid stream from a cooling loop. A condenser (120) heats the first heat exchanger fluid stream. The first heat exchange fluid stream is comprised of water and contaminant. The graphene oxide membrane is capable of allowing water to permeate through the graphene oxide membrane from the first heat exchange fluid stream to add to the second heat exchange fluid stream. USE - Heat exchange system for cooling using heat exchanger. ADVANTAGE - The strong capillary force is the driving force, rather than vapor pressure, resulting in a greater efficiency in the GO membrane. The primary purpose of the surface condenser in the steam condensation loop is to condense low pressure exhaust steam exiting one or more steam turbines to obtain maximum efficiency and also to convert the turbine exhaust steam into pure water, so as to reuse the steam generator or boiler as boiler feed water. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a heat exchange system. Closed cooling loop (10) Graphene oxide membrane (102) Pump (110) Condenser (120) Blowdown outlet (140)
