·However exceedances of Polish soil quality standards applicable until 2016 were determined for PAHs and phenols Numerous authors have pointed to the increased concentrations of phenol and PAHs in soil on the areas of coal tar processing plants [27 28 29 30] Creosote is an additional product of coal tar distillation
·Over 10 million tons of coal tar is produced every year from coal gasification and carbonization [3] As an alternative to petroleum middle and low temperature coal tar MLTCT can be considered as a suitable feedstock to produce transportation fuels via hydroprocessing which has attracted much attention and been commercialized in China
Tar production refers to the process in which organic compounds are converted into gases due to high temperature combustion resulting in negligible tar release Workers at coking plants and coal tar production plants as well as people who live near these plants have a high risk of possible exposure to coke oven emissions Studies have
·The production and processing of coal tar in Poland have a long tradition In the 70s of the last century in Poland five tar processing plants were operating and they had fully met the needs of
Domestic mid to low temperature coal tar hydrogenation technologies are investigated here All the technologies are divided into 6 steps that is coal tar hydrogenation technology of the light fraction the delayed coking tar the suspending bed reactor the full range the extractive wide distillate and the boiling bed reactor
Manufacturing process Coal tar is obtained by cooling the gas that is formed during the destructive distillation of coal to approximately ambient temperature It is a black viscous liquid composed primarily of a complex mixture of condensed ring aromatic hydrocarbons Occupational health surveillance in a German coal tar distillation
