Pitch and tar oils
Tar pitch
Tar pitch is a term for distilled remnants of a distillation process of coal tar. Coal tar is a byproduct of coke production. Consequently coke can be used during crude iron production. Due to high content of carbon and the ability to maintain liquid consistency in high temperatures tar pitch plays a key role in manufacture of special carbon-based materials. The principal application of tar pitch is to serve as a coke binding agent during carbon and graphite electrodes during production of steel and aluminium. Tar pitch is produced in different specifications based on customers' requests.
Tar Oil
Various tar oils and tar pitch are the result of distillation of tar. Some tar oils are used for production of cleaning agents, e.g. naphthalene, anthracene and carbazole. Other tar oils are used as compounds, primarily creosote oil and carbon black oil and wash oil. Creosote oil is used for pressure impregnation of railroad timber ties and timber posts. The most common use of carbon black, which is made from carbon black oil, is as hardening agents in tires and other rubber-derived products. Wash oil is used in coke plants for separating crude benzol from coke gas and other special purposes.
