Coal Tar Dewatering and Recovery

As a by-product of coke and gas produced by coking plants, coal tar has absolute practical value in industrial and medical industries. In the tar extraction process, dehydration and solid removal effects will directly affect the purity of tar. The purity of tar will directly affect its market value.

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
  1. 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.
  2. Tar quality after separation: aqueous ammonia content: <2.5%; tar content: ≥97%; solid content (> 100 μm): <0.3%.
  3. After separation, the tar in the aqueous ammonia: ≤ 4g/L.

Why Choose ZK Decanter Centrifuge ?

  • ease to use decanter
    Easy Operation

    ZK decanter can run continuously and automatically. The control of the decanter centrifuge is completed through the touch screen of the control panel, and the one-key start and stop of the decanter can be realized through the control panel. The control panel interface is simple and easy to be understood, and operators can easily monitor the working status and understand the operating parameters.

  • durable
    Durable

    All wear-prone areas of ZK centrifuges (separation liquid outlet, solids discharge output, screw conveyor and solids discharge section) are made of abrasion resistant material, and the rotating parts are made of high-strength centrifugally cast stainless steel. For the wear-resistant requirements of special industries, replaceable hard alloy wear-resistant pieces are added to the spiral blades.

  • lubrication
    Lubrication Ways

    In order to meet the actual needs of different customers, ZK decanter centrifuge provide three different lubrication ways (grease pump grease lubrication, lubricating oil circulating lubrication and oil mist lubrication) for customers to choose. All lubrication systems can re-lubricate the rotor bearings during centrifuge operation.

  • security
    Safety and Security

    ZK decanter differential speed automatic control technology can automatically adjust the screw conveyor differential speed, to prevent overload and blockage. At the same time, ZK decanter centrifuge has vibration protection, bearing temperature protection and overload protection system. This can avoid critical operating conditions and prevent damage to centrifuge components and bearings.
