Siemens PLC Control Base Oil Extraction Plants To Water Color and Odorless Base Oil

Siemens PLC Control Base Oil Extraction Plants To Water Color and Odorless Base Oil

Product Description of PLC Control Base Oil Extraction Plants

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.

Features and Advantages of PLC Control Base Oil Polishing Plant

1. Separation of Oil phase and solvent mixture with high efficiency and large treatment capacity- Maximum 2000ML/min;
2. As the improvement alternative of expensive transfer storage tanks and pumps to save cost and land occupation;
3. Two inputs of light and heavy phases Suitable for proportion, flow adjustment - Easy control the flow of oil and solvent mixing dose;
4. Adjustable weir plate size and speed - suitable for different viscosity of base oil refining;
5. Full set of explosion-proof and materials suitable for toxic and harmful media;
6. Operation in a closed system, have no pollution for environment.

 
Efficient Centrifugal Extractor of PLC Control Base Oil Extraction Plants

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.
