Profile:
Coal tar pitch distilled from by-product coal tar, generated by metallurgical coke ovens, has strategic importance for the aluminium industry. The combination of its binding properties with its high carbon content makes pitch an ideal complement to calcined petroleum coke for the production of carbon anode paste.
During the past 20 years, the steel industry has migrated from traditonal points of production in North America and Western Europe to new emerging markets. The availability of coal tar has mirroed this shift and has greatly aided in the development of pitch distillation facilities in the Ukraine and China where Jing Hao has developed local representation and expertise.
Historically, pitch was supplied in solid form. However, the trend to liquid pitch continues to grow. Whether transporting pitch in solid or liquid form, the shipment of pitch requires special handling, equipment and terminals. This is especially the case for liquid pitch which must be kept heated at all times.
Coal tar pitch (CTP) is commonly used in the aluminium smetling and roofing industries. Coal tar pitch is an amorphous residue produced by the distillation or heat treatment of coal tar, which is a by-product of coal when it is carbonized to make coke. This process typically occurs in coke ovens and can be found in steel-making plants world-wode. Exposure to aerosolized coal tar and coal tar products can bring disease for skin and breath system.
