2TPD To 200TPD Capacity Solvent Extraction Base Oil Plant To Good Performance Base Oil
2TPD To 200TPD Capacity Solvent Extraction Base Oil Plant To Good Performance Base Oil
Product Description of Solvent Extraction Base Oil Plant
PPGT-SE water white oil refining system, which is applicable for refining the following oil into good color and properties.
Base oil
Diesel oil
Waste transformer oil
Acid refined oil
Vacuum side flow oil
Black diesel
Hydraulic oil, gear oil, etc.
The refined color is less than 0.5. The viscosity, viscosity index, acid value, residual carbon, demulsification value, pour point and saturated hydrocarbon of refined base oil can reach API II or API II+ equivalent hydrogenated base oil.

Technical Flow Chart of Solvent Extraction Base Oil Plant
- Multiple stages centrifuge solvent extractor finishing times liquid-liquid extraction and separation with input base oil. Capture and separate the the aromatics and undesirable components.
- Used solvent will be sent to fractional distillation tower for recycling. Recovery rate is as higher as 99.9%.
- Extracted base oil makes its way to residual solvent stripping tower for further polishing.
- Gas generated during whole process will be collected and discharge after gas purification system.
Efficient Centrifugal Extractor of Solvent Extraction Base Oil Plant
PPGT-SE designes with many stanges centrifugal extractors, each centrifugal extractor represents once liquid-liquid extraction and separation. As higher as 2000mL/min immiscible solutions extraction and separaion, the new advanced centrifuge extraction machine optimal alternative traditional refining method or low efficient ones. The input and output rate is precisely calculated with Apsen/Pro II processing simulation by engineers from National Design Institute to ensure the oil and solvent reaction and separation well.

FAQ
1, How much oil we can get after PPGT-SE solvent extraction plant?
We can get 98%-99% polished oil from PPGT-SE; The oil loss is only 0.5%-1%.
2, What the difference between our solvent refining plant and other company`s refining plant?
Competitors adopts clay refining, acid treatment, to use solvent extraction towers or blending tank instead. It's with high chemcial consumbles and will generate secondary pollutes bad for environment. Compared with blending tank and solvent tower, PurePath adotps centrifuge extraction refining plant which is with higher efficnent, zero emissions and without secondary pollutes.
