ZK Decanters for Eco-friendly Treatment of Oil Sludge Spills

Owned by an environmental protection company, this project focuses on treating challenging land-based oil sludge. The process involves mixing bagged dirty oil sludge with semi-solid material, adding water, and heating in a workshop tank. The mixture then undergoes separation in the ZK three-phase decanter centrifuge. This efficient system recovers oil resources, with effluent water treated separately and mud repurposed in a drying plant for oil well cement. Addressing industry challenges, this centrifuge provides sustainable solutions, aligning with environmental philosophies and social responsibility.

Efficient Oil Sludge Separation with ZK Decanter in Petco

This project for a petrochemical company involves separating oil sludge with 10-15% solids. The process includes a pre-treatment—adding hydrochloric acid for rubber breakdown and emulsification, plus heating to 85°C. The treated material is efficiently processed through a decanter centrifuge, achieving remarkable separation of sludge, water, and oil. Post-separation, oil content in water reduces to 2-3%, water content in oil to 0.8%, with sludge oil content at 1.5%. The impressive 95% liquid oil recovery significantly cuts production costs and environmental impact. The decanter centrifuge, with its superior separation, large capacity, and high automation, proves ideal for oil sludge treatment, enhancing production efficiency and resource utilization.
