COALTAR DISTILLATION Occupational exposures during coaltar distillation were considered by a previous Working Group in 2005 (IARC, 2010). Since that time new data have become available, which have been incorporated in ths i Monograph, and taken into consdi eratoi n in the present evaul atoi n. 1. Exposure Data Manufacturing process
Moreover, China is a major further processor of coal tar in the world, boasting onefourth of global coal tar deepprocessing capacity in 2016. China was capable of intensively processing million tons of coal tar in 2016, down % from 2015, mainly due to decapacity after years of rapid expansion which caused massive overcapacity and then dramatic decline in utilization.
· COAL TAR. 1. The definition of the term, is also known as coking coal tar industrial coal pyrolysis gas production of the crude product, its yield coal furnace installed about 3% 4% in the ambient temperature and pressure their products black viscous liquid, /cm3 density usually between the flash point of 100 ° C has a special ...
The coal tars are complex combinations of polycyclic aromatic hydrocarbons, phenols, heterocyclic oxygen, sulfur, and nitrogen compounds. By comparison, coal tar creosotes are distillation products of coal tar. They have an oily liquid consistency and range in color from yellowishdark green to brown.
· Coal tar represents a mixture of condensable volatile products formed during the destructive distillation of bituminous coal. Composition is variable, but generally consists of 0 % to 2 % of light oils (chiefly benzene, toluene, and xylene), 16 % to 18 % of middle oils (chiefly phenols, cresols, and naphthalene), 8 % to 10 % heavy oils (naphthalene and derivatives), 16 % to 20 % anthracene ...
· China is rich in coal resources, and the production of mid‐to‐low‐temperature coal tar is increasing gradually. Due to containing more aliphatic hydrocarbons and less aromatic hydrocarbons, mid‐to‐low‐temperature coal tar is suitable for hydrogenation to produce fuel oil.

Manufacturing process Coal tar is the basic raw material for HSCL, which is obtained as a byproduct while manufacturing metallurgical coke in steel making process (blast furnace route). HSCL is the largest procurer of coal tar from steel plants in India. Coal tar is then distilled at high temperature and pressure
Established in 2005 Qinhuangdao Huarui Coal chemicals Co., LTD is a tar deep processing enterprise using internationally advanced distillation process, and it is wholly owned by the famous private entrepreneur Mr. Guoshenghua. The company is one of the key enterprises in Hebei province.
Process of destructive distillation: In this process, coal is taken in a test tube and heated. Coal breaks down to produce coke, coal tar, ammonia and coal gas. Coal tar is collected at the bottom of the other test tube and coal gas escapes out of it. Ammonia is absorbed in .

We have three plants in Hebei Province. By the end of 2006, our annual capacity of coke was about 3,200,000MT, coal tar was about 130,000MT, crude benzene was about 50,000MT, and coal tar pitch was about 72,000MT. Currently, a new coal tar distillation plant with an annual capacity of 300,000MT is under construction.
Coal tar pitch, distilled from coal tar, is used as a binder for aluminum industry carbon anodes, graphite electrodes, specialty graphite and refractory materials. RAIN, through its whollyowned subsidiaries, operates four coal tar distillation facilities in Belgium, Canada and Germany.
