ZK SEPARATION Centrifuge for Tank Bottom Oil Recovery Process
The ZK centrifuge can not only separate the oil, water, and solid components in tank bottoms. More importantly, it can also realize the recovery of high-quality oil in tank bottoms. Simultaneously, the design of our centrifuge is easy to deploy and use in the remote field. We can provide a complete system of recovery solutions for oil refining sludge, aging sludge, and slope sludge. Simultaneously, it has an automatic control system and realizes automatic continuous operation, which reduces the operating cost of personnel.
