Oil containing sludge separation and treatment system

Due to the adsorption of the same charge on the surface of oily sludge particles, which repel each other, and coupled with sufficient emulsification, it is extremely difficult to destabilize, making the separation of oil, water, and sludge quite challenging. Further conditioning agents need to be added to separate crude oil from solid particles, polymerize oil droplets, and allow the added chemical agents to settle with solid impurities, achieving further separation of oil, water, and slag. For different types of oily sludge, it is necessary to determine the optimized flocculant, demulsifier type, and centrifuge operating parameters. This type of treatment method has a wide range of applications in oil field landing crude oil, oil sludge at the bottom of oil fields and tanks, as well as the dewatering of gelatinous sludge (water content ≤ 15%) generated during the treatment of oily wastewater in oil fields. This technology is easy to operate, with a high recovery rate of dirty oil and a de oiling rate of over 80%.
