Is geothermal energy usable to produce salt from sea water?

Question

please give details of process..

Answer 1

First why is it necessary to produce salt? Salt is readily available from salt pans (salt drying beds) and requires no energy other than sunlight. Secondly, if geothermal heat is available close to shore installations, then it should be used for desalination of sea water for human consumption with the concomittent production of a slurry of concentrated brine. Energy is energy...no matter what source and can be channeled to whatever purpose needed. It matters not whether power is geothermal, nuclear or fossil-fueled. Your question is simplistic.

Answer 2

You are asking about two different concepts here. Geothermal energy is not used for salt production. It is for the production of steam which drives a turbine producing electricity. The confusion might come have arisen from the fact that geothermal plants have saline water as a by product. This is mineral saltiness not table salt, quite the opposite. Geothermal energy gets its name from its process. Pipes are driven into areas of geological instability that are allows very hot magma to come close to the surface (not too close like volcanoes - too unstable) and heat water in these pipes to steam. Hence geo - earth + therma - heat. The Earth's natural heat heats the water to steam which drives the turbine = electricity.

Salt from seawater is simply produced by the natural process of evaporation. The seawater is pumped into evaporation dams which are large and shallow and cover a very large area. The seawater evaporates and leaves behind the salt crystals which are then harvested and processed (refined and iodised). Avery simple non-technologically advanced process.

Answer 3

Could be.

The heat can be used to turn water into steam, which can then drive turbines that generates electricity to power a machine which dries sea water to extract the salt.
