Coal Tar Separation Centrifuge

Ask for quote

Coal tar – is a dark brown, viscous liquid produced during the dry distillation of coal, referred to as tar; dark brown produced during the process of coal dry distillation, has a pungent odor, a viscous liquid, and the yield accounts for about dry coal. 3 to 4%; the tar obtained by different coking temperatures can be divided into high temperature tar, medium temperature tar and low temperature tar. According to different pyrolysis temperatures, it can be divided into low temperature (450 ° C ~ 650 ° C) dry distillation tar, low temperature and medium temperature (600 ° C ~ 800 ° C) furnace tar
Medium temperature (900 ° C ~ 1000 ° C) vertical coal tar, high temperature (1000 ° C) coking tar;
The crude tar is recovered by circulating ammonia water sprayed in the coking process and condensing and cooling in the primary cooler to contain a large amount of water, containing about 4% water, sometimes reaching 8-10%;

Coaltartypicalseparation

The centrifuge has high separation efficiency and compact structure, continuous operation, the diameter of the separated particles can be reduced to 2 μm, and the treated sludge contains more than 60% solids. The clarification of the liquid and the dryness of the solid phase can be easily optimized.

The difference between low temperature and high temperature coal tar:

Component

Low Temp.
Coal Tar

Brown-black

Smaller (density is usually less than 1)

Alkanes, olefins and aromatic hydrocarbons account for 50%;Phenols: 30% High mechanical impurities, high metal impurities and high aromatic hydrocarbon content

High Temp.
Coal Tar

Black

Larger (relative density greater than 1)

It is a product of secondary decomposition of low temperature tar at high temperature, which is fundamentally different from low temperature coal tar.

The centrifuge has high separation efficiency and compact structure, continuous operation, the diameter of the separated particles can be reduced to 2 μm, and the treated sludge contains more than 60% solids. The clarification of the liquid and the dryness of the solid phase can be easily optimized.
