LCDRI is seeing the core problems. After a lot of research, it has compared various separation methods to determine the best separation process route (this separation process has obtained national patent). At the same time, the main equipment was industrialized and tested, and satisfactory results were achieved. The predetermined technical indicators were achieved and officially put into operation in 2015.
LCDRI’s sludge extraction equipment is mainly used to deal with oil sludge generated during the process of crude oil exploitation due to drilling, workover, oil recovery, gathering, storage, etc. Its function is to separate the waste sludge and extract the refined oil in the sludge, which not only solves the environmental pollution, but also realizes considerable economic value.
The equipment is armored for easy transportation, small footprint, modular device, low operating cost, good cleaning effect and easy operation. There is a mature sludge pretreatment device, which has rich experience in sludge pretreatment, automatic feeding and unloading, and automation. The oil content after solid-liquid separation treatment is three thousandths, and the treated solid phase can be used for paving, well site, brick making and other comprehensive utilization. Advanced sludge, cuttings, oil-bearing soil follow-up treatment technology, to achieve standard discharge. The utilization rate of refined oil has been improved, which not only produces good economic benefits, but also solves the problem of sludge and sand polluting the environment.
The three-phase horizontal centrifuge is used for separation. The liquid-liquid-solid three-phase separation principle is adopted, and the oil, water and mud are separately separated by centrifugal force, and the oil phase oil content after separation by the three-phase horizontal screw centrifuge is greatly reduced. The three-phase decanter centrifuge is a fully automatic, fully enclosed, continuous treatment process when the sludge is separated. The equipment has a small footprint, high automation, low labor intensity and clean working environment.
The system maximizes separation efficiency with low-cost pharmaceuticals and innovative high-automation machinery. The equipment abandons the old and imperfect production process of crude oil. For the first time, it adopts the domestic advanced physical, ultrasonic, separation and tri-integration treatment methods to fully decompose the sludge, and achieve complete separation of oil, water and mud sand.
