Wipe Film Evaporator Distillation Base Oil Refining Machine For Decolorization
Product Description of WFE Base Oil Solvent Extraction Plant
Solvent extraction function as removal of majority of the aromatics and undesirable components of oil distillates by liquid extraction. For those waste oil without solid particle, variety of recycled or crude base oil, vacuum side streams, acid-refined oil, black diesel oil, waste hydraulic oil, waste transformer oil and waste mineral oil are able to be refined to new oil in water color and outstanding performance. Particularly in application of base oil, the refined base oil can meet or approach to the API II standard in parameter of viscosity, viscosity index, acid value, carbon residue, demulsification value, pour point, saturated hydrocarbon, similar to hydrofinishing base oil.

Technical Flow Chart of WFE Base Oil Solvent Extraction Plant
Efficient Centrifugal Extractor of WFE Base Oil Solvent Extraction 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.
Successful Project Show
1, What‘s the main purpose of PPGT-SE?
It's mainly used to upgrade base oil from vacuum distillation which is without good performance could be improved to water color, increase the viscosity and viscosity index, reduce the acid value and carbon residue; aromatics could be stripped to increase the content of saturated hydrocarbon above 90% to ensure the API group II standard base oil product.
2, Could we use PPGT-SE to others oil refining?
It could also be used for improving all kinds of mineral oil like used transformer oil, hydraulic oil, turbine oil, gear oil, all vacuum side streams, traditional distillation recycled red base oil, acid and alkali treatment base oil, TEPA and clay treated base oil.
