3-6 Stages Centrifuge Type Base Oil Refining Machine To API Group II Oil
3-6 Stages Centrifuge Type Base Oil Refining Machine To API Group II Oil
Product Description of Centrifuge Type Base Oil Refining Machine
All kinds of regenerated base oil, vacuum side line, acid refined oil, black diesel oil, waste liquid pressure oil, waste transformer oil and all kinds of waste mineral oil without solid particles can be refined into new oil. The color is water color and the color scale is less than 0.1. The viscosity, viscosity index, acid value, carbon residue, demulsification value, pour point and saturated hydrocarbon of refined base oil can meet or approach API II standards, properties as hydrogenated base oil.

Technical Flow Chart of Centrifuge Type Base Oil Refining Machine
- 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 Centrifuge Type Base Oil Refining Machine
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, 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.
