The Quality of Coal Tar and Technology of Its Preparation for Processing

摘要

In Russian byproduct coke plants the principal method of preparation of coal tar for processing is gravitational settling. This method is successfully used in the Altai-Koks plant There are four coke-oven batteries in the plant with a useful chamber volume of 41.6 m~3. The first battery was put into operation in December 4, 1981. The coke-oven gas produced in these batteries is transferred, according to the flowsheet of condensation sections Nos. 1 and 2, to the separator of coke-oven batteries Nos. 1-4. Here the gas and liquid phases are separated. The liquid phase from the separators of batteries Nos. 1-3 is carried to mechanized clarifying settlers of condensation section No. 1, and after the separator of battery No. 4 it is sent to mechanized clarifiers of condensation section No.2. The flowsheet provides for the transfer of coal tar and liquor after the separator KB-3 to mechanized clarifiers of section No. 3.
