Chemical connections

Caustic soda
TCL is able to deliver low-cost caustic soda to the market due to its adoption of energy-efficient, membrane-cell technology and the captive availability of salt and of power at the Mithapur facility. As a versatile alkali, caustic soda is used in a variety of industries, the major ones being rayon, cellophane, soap, pulp and paper.

Chlorine based products
TCL produces hydrochloric acid and liquid chlorine at its Mithapur facility.

Tata Chemcials Europe makes and sells calcium chloride in its UK facilities.

Bromine based products
TCL manufactures several variants of bromine and bromine-based compounds, such as liquid bromine technical, hydrobromic acid and sodium bromide (photographic grade).

Bromine is used primarily in the manufacture of organic and inorganic bromides. It is also used as a crucial reagent in preparing several organic compounds requiring bromination. Other variants are used in the preparation of photographic emulsions, for processing photographic films and paper, in lithography, as an analytical reagent, as a soil fumigant , and in the making of flame retardants, drilling fluids, water treatment, dyes, and brominated pesticides.

Gypsum
Gypsum, formed in crystalline lumps or powder form, is yet another product from the Tata Chemicals stable.

Gypsum is used as an ingredient for Portland cement, for soil treatment, and to stabilise volatile compounds and dissolve nitrogenous ones. It also finds use as an inert filler in paints, paper, pharmaceuticals, insecticide dusts, etc.

Phosphoric and sulphuric acids
TCL's Haldia plant produces industrial grade phosphoric and sulphuric acids; these are inputs to the manufacturing of phosphatic fertilisers at the plant, and are also a part of TCL's product portfolio.

Uses: Phosphoric acid is a key input to the manufacture of phosphatic fertilisers. Sulphuric acid's uses include ore processing, fertiliser manufacturing, oil refining, wastewater processing and chemical synthesis. The major use of sulphuric acid globally is in the wet process for manufacture of phosphoric acid.
