Abstract
A method and apparatus for desalinating water combined with power generation, wherein a desalination system is used for desalinating coastal seawater and is operationally related to a power generation system, wherein such dual purpose co-generation facility captures the heat vapor exhausted or a steam turbine generator's condenser is replaced by the desalination plant's heat exchanger enabling such captured heat energy to reduce the energy requirements of the desalination plant, and wherein brine solution being utilized by the desalination plant is circulated from and to the substrata sea water table via supply and return wells.
Claims9
A process for improving the thermal and energy efficiency of a desalination process, comprising the steps of:
- providing at least one power generation turbine for generating electricity for a power grid, wherein said turbine has a heat source;
- providing at least one desalinating train having one or more distillation stages coupled to said heat source for removing salt from seawater to make potable water;
- drilling at least one brine supply well for pumping brine from a substrata sea water table for processing by said desalinating train;
- and
- drilling at least one brine discharge well for injecting a brine by-product from said desalinating train into said substrata sea water table.
