Carl L Elmore: Carrier gas apparatus for evaporation and condensation. Kamyr, Nixon & Vanderhye, March 17, 1992: US05096543 (10 worldwide citation)

The waste heat from a steam turbine is condensed and used to desalinate sea water at the same time. The waste steam from a turbine is fed to a condenser through which cold sea water passes. As the cold sea water condenses the waste steam, it is warmed. It is then introduced into a first chamber whic ...
