Service Case

In coal tar separation, ZK centrifuge equipment offers customers efficient and reliable solutions, garnering favorable feedback. Years of practical experience and technological innovation empower our equipment to effectively handle complex coal tar mixtures, ensuring efficient separation. If you are seeking the optimal coal tar separation solution, ZK equipment stands as your reliable choice.

ZK Decanter Applied to Coal Tar Separation Project

The project aimed at the three-phase separation of coal tar. Prior to treatment, the coal tar had a toluene-insoluble matter content of approximately 3.5% and an ammonia content of around 10%. Following the three-phase separation treatment using the ZK decanter centrifuge, the discharged tar exhibited a reduced ammonia content of no more than 2.5%, while the tar content reached ≥97%. The data above illustrates the ZK decanter centrifuge's efficiency in removing impurities and impurity components from coal tar, enhancing the tar's purity and quality. Currently, the ZK decanter centrifuge is widely employed in the three-phase separation process of coal tar, significantly improving tar quality and yield, and contributing to the advancement of related industries.
