ZK SEPARATION Decanters for Coal Tar Recovery Process
ZK decanter centrifuge has huge technical advantages in the recovery process of coal tar. Because we have more than 20 years of experience and technology precipitation in industrial centrifuges, ZK coal tar decanter can be used in the dehydration and solid separation process in the tar recovery process of the coking plant. It can effectively separate solid impurities and water from the tar and extract high-purity tar. Simultaneously, our equipment has the characteristics of anti-wear protection and continuous operation and is equipped with an automated control unit, which can significantly reduce the labor operation cost and save the company the most considerable degree of production and operation costs.

Tar Decanter Separation Performance
- The centrifuge features high separation efficiency, compact structure, and continuous operation. The diameter of the separated particles can be reduced to 2 μm. The solid content (toluene insoluble matter) in the treated coke button is more than 45%, which can easily optimize the clarification of liquid and the dryness of solids.
- Tar quality after separation: aqueous ammonia content: <2.5%; tar content: ≥97%; solid content (> 100 μm): <0.3%.
- After separation, the tar in the aqueous ammonia: ≤ 4g/L.
