YJ-SR Base oil Solvent Desulfurization Machine
YJ-SR Base oil Solvent Desulfurization Machine
Deeply purify and refine all distilled oil,improve the oil standard close to API Group II
Why We Develop Solvent Extraction Machine?
With the higher and higher requirement on base oil quality of downstream petrochemical enterprises especially the base oil blending factories, with some old-fashioned technology, the recycled base oil quality is hard to meet the requirement of the downstream user. Before the expensive and technologically complex hydrogenation technology is widely used in oil recycling factory, there are many re-refining technologies, such as fuming sulphuric acid refining technology, lewis acid refining technology, this technology is better than the old fashioned technology, but there’s still a big gap from hydrogenation technology, the environmental pollution problem, the acid sludge, waste white clay disposal are big problems.
Wide Applicantion of YJ-SR Base oil Solvent Desulfurization Machine
- Base oil (distillate,like our YJ-TY series, base oil after the acid process);
- Diesel (cracking diesel from waste oil);
- Black diesel;
- Vacuum cut distillate oil;
- Acid-treated oil/Acid refined oil;
- Lube-cutOther waste mineral oil which doesn’t contain solid particle and water.
Through YJ-SR Base oil Solvent Desulfurization Machine, the purity and quality of base oil can be improved,close to the standard requirements of API Group II base oil classification with water white color, increasing the viscosity index of base oil, reducing sulfur content, increasing saturation, and removing impurities.
How the Solvent React With the Oil?
The solvent and oil are two immiscible solutions, both two immiscible solutions of different densities are pumped into the extractor through two entrances respectively, and then rapidly mixed in the gap between the drum and the shell, and the mixed liquid enters the drum through the inlet at the bottom of the drum, and the accelerated heavy phase is thrown to the lateral side of the drum. the light phase remains on the inside of the heavy phase, the two-phase interface is between the light phase outlet and the heavy phase underflow channel, and the heavy phase underflow channel is in the upper part of the separation zone composed of heavy phase enthalpy.
There is a five-stage separator, the oil and solvent were separated two-layer due to the different densities after heating and reacting, the up layer is oil, and the bottom layer is solvent. five times, the oil becomes to water-white color.
Working Principle of Centrifugal Extractor
Liquid-Liquid centrifugal extractor can separate two different immiscible liquids, it has been used widely in industries such as the oil extraction, pharmaceutical, fine chemical, food products, Environmental protection industry and wastewater treatment, etc. Our company can design and adjust centrifugal speed or inlet quantity of the centrifugal extractor according to the density of the different liquid mediums.
Advantage of Centrifugal Extractor
- The performance of the flexible upper suspension structure is better than that of the rigid structure, and it can be self-aligned. High speed, large aspect ratio, high extraction efficiency and good separation effect.
- Low power consumption.
- Easy operation and maintenance.
- Less space area need.
- Good adaptability: Compared with traditional van and tower extraction equipment, it has short retention time, rapid phase separation, and a wide range of adaptable flow ratios; it can meet liquid materials with different densities and different viscosities by replacing weir plates and frequency conversion speed regulation.
- Low investment cost: The internal volume of the machine is small, and the consumption of solvent is minimal.
- Good airtight performance: it meets the application environment and GMP regulations of explosion-proof,toxic, harmful and volatile media.
Parameter—Base Oil Index
The base oil is treated by YJ-TY&YJ-SR base on used diesel engine oil:
| NO | Item | Unit | Light base oil | Medium/heavy base oil |
| 1 | Viscosity（40℃） | mm2/s | 16~32 | 28~72 |
| 2 | Viscosity index | ≥99 | >110 | |
| 3 | Color index | ≤0.3 | ≤0.5 | |
| 4 | Pour point | ℃ | -15 | -10 |
| 5 | Flash point（open） | ℃ | ≥180 | ≥200 |
| 6 | Ash content | %（W/W） | 0.002 | 0.004 |
| 7 | Carbon residue | %（W/W） | ≤0.05 | ≤0.08 |
| 8 | Saturated hydrocarbon | % | 96 | 98 |
| 9 | Acidity | mgKOH/g | ≤0.01 | ≤0.01 |
Note: The waste oil composition will affect parameter index.
Yangjiang has been committed to solving various waste oil purification problems,in addition to the above waste oil recycling plants, we also provide other used oil re-refining plants, such as Used Oil to Base Oil Plant, Waste Oil to Diesel Oil Distillation Plant,Diesel Desulfurization Machine,Base Oil Blending Plant,Transformer Oil Regeneration Machine.
