Obtaining Clorine from SEAWATER

[otc]

Hello to you
if it is posible for you ,Show me the best method and existed method for producing CHLORINE from seawater also
If you know about related references or textbooks, please show us,
In last , IF YOU KNOW BOUT THE EXISTANT EQUIPMENT IN MARKETS FOR PRODUCING CHLOR OF SEAWATER ,please INFORM US.

Thank you.

Its Very simple process but involves costly equipment (initial investment is higher but operating cost is extremly low).Sea water is nothing but brine solution in natural form.

I know of a company manufacturing such equipments and you can contact them in INDIA :at wape14@hotmail.com

Checking existing industrial processes used by the chlor-alkali industry will provide insight. Brine solutions used in industry are quite concentrated, and purer NaCl, compared to seawater. Chlorine plants usually sit on salt deposits which are often solution mined. Solution mining an old dried seabed is likely more competitive than "mining one that isn't dried and concentrated yet"...ie - seawater...
Good luck...

Otc,

You going for the latest technology with very very very very high invesment.

Good Luck

You don't say how much chlorine you need to produce, and that will impact the process design and equipment selection. The unit operations involved are generally; 1. Concentration, usually by membrane, but can be evaporation; 2. Purification, usually a combination of chemical treatment and sludge removal followed by ion exchange; 3. Electrolysis ; 4. Cooling; 5. Compression. Then you must deal with by-products of hydrogen gas and sodium hydroxide.

Some of the most knowledgeable people are Chlorine Engineers in Japan. Here is a link to their web site.
