Abstract
A submerged offshore reverse osmosis desalination apparatus and method uses desalinated product water from the apparatus and an onshore cooler or heat exchanger to provide or improve the cooling of an onshore Rankine Cycle heat engine.
Claims18
A desalination and cooling system comprising a submerged offshore reverse osmosis desalination apparatus having:
- a) one or more submerged osmotic membranes each having an inlet surface supplied with seawater at least partially under hydrostatic pressure and an outlet surface that provides desalinated product water containing less than 0.5 parts per thousand (ppt) dissolved inorganic salts by weight to a submerged product water collector in fluid communication with the outlet surface(s),
- b) an at least partially submerged water discharge conduit in fluid communication with the collector and providing a pipeline that delivers the desalinated product water to shore;
- and
- an onshore cooler or heat exchanger in fluid communication with the water discharge conduit,
- wherein the desalinated product water and onshore cooler or heat exchanger provide or improve the cooling of an onshore Rankine Cycle heat engine.

A method for desalination and cooling, the method comprising operating a submerged reverse osmosis desalination apparatus having:
- a) one or more submerged osmotic membranes each having an inlet surface supplied with saltwater at least partially under hydrostatic pressure and an outlet surface that provides desalinated product water containing less than 0.5 parts per thousand (ppt) dissolved inorganic salts by weight to a submerged product water collector in fluid communication with the outlet surface(s),
- b) an at least partially submerged water discharge conduit in fluid communication with the collector and providing a pipeline that delivers the desalinated product water to shore;
- and
- using the desalinated product water in an onshore cooler or heat exchanger in fluid communication with the water discharge conduit to provide or improve the cooling of an onshore Rankine Cycle heat engine.
