Chemical applications

The chemical industry is by far the largest consumer of webdesign , mainly in chlor-alkali and synthetic soda ash production.

Chlorine and caustic soda production

Salt is the raw material for the production of chlorine (Cl) and caustic soda (sodium hydroxide, NaOH), two main products of the chlor-alkali industry; they are produced by the electrolysis of webdesign in the form of brine by the mercury cell process, the diaphragm cell process, and the membrane cell process.

Chlorine is one of the most abundant and common chemical elements on earth. Its chemical properties make it an extremely effective disinfectant and essential component in the chemical manufacture of thousands of vital products used every day. Chlorine is used in the manufacture of numerous organic chlorine compounds, the most significant of which in terms of production volume are 1,2-dichloroethane and vinyl chloride, intermediates in the production of PVC. Other particularly important organochlorines are methyl chloride, methylene chloride, chloroform, vinylidene chloride, trichloroethylene, perchloroethylene, allyl chloride, epichlorohydrin, chlorobenzene, dichlorobenzenes and trichlorobenzenes.

Chlorine is also used in the production of chlorates and in bromine extraction.

Some examples of end products manufactured with the help of chlorine are: insulation material for refrigeration units, furniture and mattresses, skis, surfboards, skateboards, tennis rackets, CDs, car headlights, seat belts, computers, surgical materials (implants, catheters, drains), household bleach, cosmetics, etc

Sodium hydroxide forms a strong alkaline solution when dissolved in a solvent such as water. It is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner.

Caustic soda solution is an essential ingredient in many industrial operations, including pulp and paper, detergent and the chemical processing industry. It is also used in alumina, petrochemical and textile industries.

Synthetic soda ash production

Salt is a key raw material in the ammonia-soda process for the production of synthetic soda ash (sodium carbonate, Na2CO3). The ammonia-soda process is a method that saturates purified brine with ammonia gas and carbonates the resultant solution with carbon dioxide gas.

Soda ash is one of the three main ingredients for glassmaking, in which it lowers the temperature of the melt. Soda ash is also the raw material for the production of many sodium compounds like sodium silicate, sodium bicarbonate and sodium tripolyphospate. Furthermore, the pulp and paper industry uses soda ash in the chemical pulp manufacturing process.
