Full Continuous Automatic Base Oil Extraction Plants With Fractional Distillation Column
 
 
Product Description of Full Automatic Base Oil Extraction Plant
 
With PurePath further treatment centrifuge solvent extraction plant, it could upgrade the API group I base oil into API group II base oil with less than 0.5 ASTM color scale. The machine adopts four stages centrifuge extractors with PLC/SCADA automatic control to ensure the completely continuous operation. As the optimal alternative of acid refining or clay refining, solvent extraction is without any chemical consumption and without waste generated to bring secondary pollution.
 
 
Highlights of Full Automatic Base Oil Extraction Plant
 

1. Multiple feeds: to refine all kinds of recycled base oil, vacuum side streams,acid-refined oil, black/red diesel oil, waste hydraulic oil, waste transformer oil and other kinds of waste mineral oil.
2. Multistage centrifugal extractors could be stable and high efficient refining different feeds with different viscosity.
3. No secondary pollutes for environment: no waste generated during solvent extraction.
4. Low cost of manpower: Siemens PLC/SCADA control to ensure the automation and continuously operation.
5. Thin film evaporator and wiped film evaporator to strip the solvent from polished oil.
6. High efficient solvent regeneration fractional distillation tower to produce much pure recovery solvent.
7. Polished oil is less than 0.5 ASTM color scale almost water color.
8. Less than US$12 of solvent consumption to refine 1 ton feed oil.

Technical Flow Chart of Full Automatic Base Oil Extraction Plant

 

1. 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.
2. Used solvent will be sent to fractional distillation tower for recycling. Recovery rate is as higher as 99.9%.
3. Extracted base oil makes its way to residual solvent stripping tower for further polishing.
4. Gas generated during whole process will be collected and discharge after gas purification system.

 
Efficient Centrifugal Extractor of Full Automatic Base Oil Extraction Plant

 
PPGT-SE designes with multiple stange 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.
 
3, 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%.
