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.

Pitch is marketed in solid and liquid form. Solid pitch is available in bulk bags and jumbo bags. Liquid pitch is supplied with the help of the Companys dedicated fleet of specialised tanker. Himadri also has bulk liquid pitch terminal to load up to 6,000 MT at Haldia port and is currently constructing a new liquid pitch terminal at Lonkou port in China, capable of loading 12,000 MT of liquid coal tar and pitch.
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.
