Coal tar distillation

Pitch

Features

Coal tar is a by-product generated while processing coking coal into low ash metallurgical coke in a recovery-type coke oven plant. Coal tar accounts for around 3.5-4% of coke produced. Coal tar pitch is a complex chemical with 22 chemical and physical properties obtained through coal tar distillation, which involves the conversion of coal tar into a variety of intermediate chemical products. The residue is coal tar pitch, which is further processed into quality coal tar pitch of desired chemical and physical properties. At, Himadri, coal tar pitch is derived from the processing of high temperature coal tar using state-of-art technologies.

Naphthalene

Features

Naphthalene is used in the manufacture of SNF, beta naphthol, phthalic anhydride, tanning agents, moth balls and domestic disinfectants. During the distillation process, approximately 8-9% naphthalene is recovered for use dye and organic compound intermediates in fine chemicals and pharmaceuticals. Globally, coal tar is the major source of naphthalene.

Aluminium Industry

Aluminium is the metal of the future, combining lightness with strength, electrical conductivity and corrosion resistance. The widespread use of aluminium extends to the aerospace, automobile white goods, food and beverage packaging. Owing to the many applications for this metal, primary aluminium production throughout the world has been rising steadily for many years. Coal tar pitch is used as binder for production of carbon anodes which in turn is used in the electrolysis process of extracting aluminium from alumina by the aluminium industry. Aluminium plants can only be successful with binders of constantly high quality. Himadri is a preferred vendor, delivering high quality binder pitch (solid and liquid) just in time to aluminium plants.

Graphite industry

Coal tar pitch is used in the production of graphite electrodes (used in steel production) as a binder, and impregnating agent, increasing electrode density and strength. After the aluminium industry, the second largest consumer of coal tar pitch is graphite electrodes (which are used in electric arc furnaces). CTP constitutes around 40-42 percent of a graphite electrode by volume, with a large part of the balance being accounted for by needle coke/CPC (calcinised petroleum coke). CTP is used as a binder and impregnating material in electrodes at a high temperature to fill and cover pores, enhancing electrode life.

Infrastructure Sector

Concrete is one of the most important and versatile building materials of recent times. Himadri produces naphthalene-based super plasticisers that have revolutionised the use of concrete. Super plasticisers improves cement mix by dispersing cement particles, improving its flowing properties and making it easier to handle and feed to even the most remote corners of a building. These substances also reduce processing times and increase the strength of the concrete. With the construction sector booming, Himadri therefore plans to boost its super plasticiser production capacity and expects annual growth rates in excess of 25%.

Tyre sector

Global carbon black consumption is growing at 3-5% annually. Southeast Asian countries are growing at a pace of more than 6% annually. Carbon black is one of the main raw material for tyre industry and increases tyre grip on road. Its low resistance and minimum abrasion loss makes the highest safety possible. Himadri, with its latest state-of-the-art technology, is ensuring rubber compound with minimum grit and top ranging modulus.

Lithium-ion Batteries

Himadri is one of the few companies in the world to develop the technology to manufacture high-quality advanced carbon material which enjoys downstream applications in the manufacture of lithium-ion batteries. Lithium-ion batteries are used across all portable electronic devices like mobile phones, video cameras, notebook computer and palmtops; they also find application in hybrid vehicles and electric vehicles. The primary batteries are replaced by high energy lithium-ion batteries. Toyota including many other car manufacturers has already begun to test the lithium-ion batteries for car start-up applications. Lithium-ion is a low maintenance battery, an advantage over peers. The self- discharge is less than half compared with nickel-cadmium, making lithium-ion well suited for modern fuel-gauge applications.

Power sector

Power has been universally recognised as one of the most important inputs for economic growth and human development. There is a strong two-way relationship between economic development and energy consumption. India has been traditionally dependent on thermal power, which constitutes about 63% of the current capacity. The balance is contributed by hydroelectric (25%), nuclear (3%), and renewable (9%) energy sources. The overall power generation in the country increased from 704.469 billion units in 2007-08 to around 723.794 billion units in 2008-09 (2.74% growth).The growth was significant for the hydro (8.38%) and thermal (5.57%) sectors while nuclear power generation declined 12.3%. Himadri is emerging as separate power division. A power plant of 15 MW is being set up with green and clean energy. The power plants are eligible to carbon credits.

Paints and coatings

Carbon black is a key raw material that enhances the performance of rubber, inks and paints. Himadri produces carbon black engineered to meet the needs of these end-market applications. Himadri’s carbon black can be used in a wide variety of coating applications. Although its definition is simple, a coating can be sophisticated in terms of composition, curing chemistry and application performance. Industrial carbon blacks are used in a variety of applications, including printing inks, toners, coatings, paper and building products. Purposes for using industrial carbon black include pigmentary, electrical, UV absorption and theological properties.

Plastics

The Company has designed different carbon black varieties for various plastics applications. The range of applications is diverse but it is not limited to basic colour concentrates for pigmentation, electrostatic dissipation, fibres, film, pipe, UV protection/stabilisation and wire and cable compounds.

Dyestuff Sector

Himadri produces naphthalene which is used in products of dye intermediates such as H-Acid, Beta Napthol and reactive dispersing dyes. We use these dyes as colours in our everyday life.
