Desulfurization Refinery Machine By Solvent Extraction and Centrifuge Extraction Technology​

Product Description of Engine Oil Re-Refining 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 Engine Oil Re-Refining 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 Engine Oil Re-Refining Plant

The principle of high-speed centrifugal contactor is: two immiscible solutions with different densities are pumped into the extractor through two inlets respectively, and then quickly mixed in the gap between the cylinder and the shell. The mixed liquid enters the cylinder through the inlet at the bottom of the cylinder, accelerating the heavy phase to be thrown to the side of the drum. The light phase is located inside the heavy phase, the two-phase interface is located between the light phase outlet and the heavy phase underflow channel, and the heavy phase underflow channel is located in the upper part of the separation zone composed of heavy phase enthalpy.

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.
