Base oil solvent extraction equipment
Base oil extraction equipment primarily utilizes the difference in solubility of different substances in specific solvents to achieve the separation and extraction of base oil. Its working principle is as follows:
1. Solvent Selection
Using organic solvents with different solubility characteristics of ideal and non ideal components to purify base oil for better sulfur content, antioxidant
2. Mixing and Dissolution
Thoroughly mix the base oil with the solvent. Under certain temperature and pressure conditions,the non-ideal components in the base oil dissolve in the solvent and then.
3. Separation Stage
After synchronous high-speed rotation of the mixed liquid and the drum, centrifugal force is generated.The high-density liquid(solvent)approaches the drum wall,while the low-density liquid(base oil) gradually moves towards the center. Finally, the two liquids come out through their respective channels,achieving liquid separation.
4. Solvent Recovery
Treat the solvent phase containing the base oil by changing the temperature and pressure to evaporate or volatilize the solvent, thereby separating the base oil. The recovered solvent can be recycled to reduce costs.

Comparison Of Parameters
VBT-SE solvent extraction plant is specifically designed to upgrade and purify base oils recovered from waste lubricant and motor oil recycling. Its primary function is to convert mid-grade feedstock into high-value base stocks.
Refineries use this plant to process distilled base oil, effectively removing residual aromatics, sulfur, and unstable compounds that simple distillation cannot eliminate.
In addition, the plant enables dual revenue streams:
The main output—purified raffinate—offers enhanced viscosity index and stability, making it ideal for blending top-tier engine oils and industrial lubricants.
The separated aromatic extract can be directly used as a high-quality component in process oils for the rubber and tire industry, or as a valuable blend stock for fuel oils.

technology introduction
Group I&II base oil can be obtained by the following technology:
（1）Pretreatment to remove particle and impurities from oil, Filter/Flocculant Precipitation/Centrifuge are optional.
（2）Adopt independent operating system of flash distillation technology for dewatering primarily.
（3）Oil vapor will evaporate at different boiling points to produce base oil in the fractionating distilation column. Then combined with large area condensers to improve oil gasification efficiency.
（4）Refining process: can choose clay, silicone sand, solvent extraction according to the market demand.
The whole process is environmental- friendly ,the colloid and asphaltene in the waste engine oil are all into sludge, can be used as asphalt/bitumen.

Concept and Overview
"Our company’s multi-stage base oil solvent extraction and refining equipment utilizes a targeted solvent blending process and a closed-loop solvent regeneration system to produce API VI ultra-high viscosity index base oils, achieving a solvent recovery rate of about 98%, meeting the strict requirements for high-end lubricants, synthetic materials, and specialty chemicals."
Base oil extraction equipment has the following advantages:
1. High-efficiency separation
(1) It can accurately separate different components in the base oil, effectively removing impurities and improving the purity of the base oil.
(2) Compared with traditional methods, the separation efficiency is higher, and a large amount of raw materials can be processed in a shorter time.
2. High product quality
(1) The extracted base oil has stable quality and good performance. It can meet the production needs of various high-end lubricating oil products.
(2) Effectively removes undesirable components such as resin and asphalt, giving the base oil better oxidation resistance, low-temperature fluidity, and other performance indicators.
3. Environmentally friendly and energy-saving
(1) The solvent solution is coloress and non-toxic, and the entire operation process is also environmentally friendly and harmless.
(2) Some extraction processes have relatively low energy consumption, and the solvent can be recycled and reused, reducing energy consumption and production costs.
4. Flexible operation
(1) According to different raw material properties and product requirements, process parameters and solvent selection can be adjusted to adapt to various types of base oil extraction needs.
(2) The equipment can be operated continuously or intermittently to meet the production requirements of different scales.
5. Good economic benefits
(1)The process of extraction is thoroughly separated, which can greatly reduce the amount of extraction solution used and thus reduce the cost of processing.
(2) The high-quality base oil produced has high market value and can bring good economic benefits to the enterprise.
