CAUSTIC SODA
Caustic Soda, chemically called Sodium Hydroxide (NaOH), is a basic product widely used in diverse industrial sectors, either as a raw material or as an auxiliary chemical. It is produced along with chlorine and is produced in two forms – lye and solids. Solid Caustic Soda can be in the form of flakes or granules.
DCW produces Caustic Soda using the latest energy efficient and environment friendly Mercury free state-of-art Membrane Cell Technology.
Capacity: 100,000 TPA
Application: Caustic Soda is mainly used in the manufacture of pulp and paper, newsprint, viscose yarn, staple fibre, Aluminium, cotton, textiles, toilet and laundry soaps, detergents, dyestuffs, drugs and pharmaceuticals, vanaspati and in petroleum refining.
LIQUID CHLORINE
Chlorine is a by-product in the production of caustic soda. Being a gas and due to its hazardous nature, it cannot be transported over long distances. Therefore, DCW produces other chlorine products from Chlorine in its complex. Internationally, Chlorine is a main product and caustic soda is the by-product but in India, caustic Soda is a main product and chlorine a by- product as development of chlorine-based products has not occurred
Capacity: 36,000 TPA
Application: Chlorine is used in the manufacture of products like vinyl, pharmaceuticals, water disinfectants, agrochemicals, additives in oil and detergents, refrigerants, photographic chemicals, adhesives, inks and coatings. It also finds application in multiple industries such as electronics and semi-conductors, food processing, automotive, and public health. Chlorine is also used in the manufacture of Trichloro & Perchloro Ethylene
HYDROCHLORIC ACID
Hydrochloric Acid (HCl) is a colourless and odourless solution of hydrogen chloride and water. Once commonly referred to as muriatic acid or spirit of salt, this acid is a highly corrosive chemical compound with several applications in industry. It is also found in diluted amounts in the stomach of humans and animals as gastric acid.
DCW’s Hydrochloric Acid is a guaranteed Mercury Free acid with minimum 30% concentration.
Capacity: 90,000 TPA
Application: Hydrochloric Acid is used in the pickling of steel to remove rust or iron oxide scale from iron ore before processing, production of organic and inorganic compounds, pH control & neutralization and regeneration of ion exchangers. Hydrochloric Acid is used in a number of small-scale applications such as leather processing, purification of common salt, household cleaning and building construction.
SYNTHETIC RUTILE
Synthetic Rutile is a product containing min. 94% TiO2 of golden yellow colour and without specific odour. It is a multi-stage manufacturing process employing controlled reduction, oxidation and acid leaching
Capacity: 42,000 TPA
Application: Synthetic Rutile is used in pigments (for paints, coatings, Plastics etc) and welding electrodes
TRICHLOROETHYLENE
Trichloroethylene (TCE) is a non-flammable, colourless liquid with a somewhat sweet odour and a sweet, burning taste.
Capacity: 7,200 TPA
Application: Metal de-greasing, dry cleaning, drying electronic parts; as extraction solvent for oils, fats, waxes, refrigerant and as fumigant.
YELLOW IRON OXIDE
Yellow Iron Oxide (Fe203H2O), also known as Hydrated Ferric Oxide, is a yellow odourless powder and insoluble in water. It is manufactured by the precipitation process using leach liquor – a waste from Ilmenite production.
Capacity: 450 TPA
Application: Yellow Iron Oxide is used primarily as a pigment.
FERRIC CHLORIDE
Ferric chloride is an industrial scale commodity chemical compound. The color of Ferric Chloride crystals depends on the viewing angle: by reflected light the crystals appear dark green, but reflected light they appear purple-red. Anhydrous Ferric Chloride is deliquescent, forming hydrated hydrogen chloride mists in moist air.
Capacity: 6,000 TPA
Application: Industrially Ferric Chloride is used in sewage treatment and production of drinking water. Amongst other unconventional uses, it is also used as a drying reagent in certain reactions, used in making print circuit boards and test pitting and crevice corrosion resistance of stainless steel and other alloys
UTOX (UPGRADED ILMENITE)
Utox is a pigment with 89-92% Titanium Dioxide (TiO2) content. It is pale yellow in colour and odourless. Utox is manufactured by recovering the fine particles of Titanium Dioxide from the liquor blown down during the leaching process of Ilmenite.
Capacity: 1,800 TPA
Application: Utox is mainly used in industrial paints and power coatings.
PVC
DCW produces Poly Vinyl (PVC), a white powder from vinyl Chloride Monomer by suspension polymerization process. PVC is a thermoplastic resin, which in versality of processing and application surpasses all other thermoplastic materials. This unique polymer is one of the oldest established plastics.
Capacity: 90,000 TPA
Application: PVC finds applications in insulation of cables, in pipes and hoses, agricultural products, windows and profiles, flooring tiles used in the building industry, blister packaging, films and sheets, foamed leather cloth, curtains, tarpaulins, and also for medical use – for IV, blood bags, etc. The versality of its properties is such that new areas of application are being continuously developed.
SODA ASH
Soda Ash, also known as Washing Soda or Sodium Carbonate (Na2CO3), is a sodium salt of carbonic acid. It most widely occurs as a crystalline heptahydrate, which readily effloresces to form a white powder, the monohydrate. It is synthetically produced in large quantities from salt and limestone in a process known as the Standard Solvay Process. As a Chemical Manufacturer, DCW produces premium quality Soda Ash enabling our customers to produce high-quality products.
Capacity: 96,000 TPA
Application: Soda Ash is primarily used for manufacture of detergent powder, cake and glass. It is also used in oil well drilling, in hygiene and cleaning products. Soda Ash is also used in effluent treatment, water treatment, in pulp and paper manufacture, in dyes, dye intermediates, brine purification, ore refining, cooling agents, pesticides, drug intermediaries, paper, chemicals etc.
Soda Ash is widely used in the production of other chemicals such as Sodium Silicate, Sodium Chromate, Sodium Bichromate, Sodium Bicarbonate and other Sodium Salts.
It is also used as a relatively strong base in various settings. For example, sodium carbonate is used as a pH regulator to maintain stable alkaline conditions necessary for the action of the majority of developing agents. It is a common additive in swimming pools used to neutralize the acidic effects of chlorine and raise pH.
SODIUM BICARBONATE
Sodium Bicarbonate (NaHCO3) is a white, extremely pure substance. It is not only non-toxic and biodegradable, but also human and environment friendly. Since it has long been known and is widely used, the salt has many related names such as Baking Soda, Bread Soda, Cooking Soda, Bicarbonate of Soda. Colloquially, its name is shortened to Sodium Bicarb, Bicarb Soda, or simply Bicarb.
Capacity: 100,000 TPA
Application: Sodium Bicarbonate is an all-purpose product that can be used in a variety of sectors, such as Foods and Animal Feeds, Domestic Applications, Personal Hygiene and many others. It is mainly used for cooking (baking), neutralization of acids and bases, medical applications and personal hygiene products. Since Sodium Bicarbonate acts as a neutralizing agent, is soluble and is slightly abrasive, it is the ideal product to safely remove persistent odours and stubborn stains.
AMMONIUM BICARBONATE
Ammonium Bicarbonate (NH4HCO3) is a white, crystalline powder with a slight odour of Ammonia that can dissolve in water to give a mildly alkaline solution.
Capacity: 5,000 TPA
Application: Ammonium Bicarbonate is used in the food industry as a raising agent for flat-baked goods (e.g., gingerbread).
