SR Solvent Extraction Refining Machine
Yangjiang's solvent extraction refining machine can reduce sulfur and change color for base oil and diesel oil, It also can refine vacuum side streams, acid-refined oil, black diesel oil, waste hydraulic oil, waste transformer oil and the oil from crude oil refinery machine to new oil, with water-white color, the color is less than No.0.1. The viscosity, viscosity index, acid value, carbon residue, demulsification value, pour point, saturated hydrocarbon of refined base oil can reach or close to the API II standard, like hydrogenated base oil. Also, SR can reduce sulfur from diesel oil to less than 50-100ppm.
If you already installed a oil distillation machine, thin-film evaporation machine, if your oil color is easy to change back to brown, and if you want to reduce sulfur, you can choose Yangjiang's SR solvent extraction refining machine. Solvent extraction is the term used for the removal of most of the aromatics and undesirable constituents of oil distillates by liquid extraction. Commonly used solvents contain phenol, furfural and sulfur dioxide. The resulting base stocks are raffinates (referred to as neutral oils) and an extract that is rich in aromatic content, which is highly sought after as a process oil or fuel oil.
We adopt a complex solvent, which can exact the oil color to white, reduce sulfur to 50ppm. what's important, this machine contains a solvent recovery system, which can recover the used solvent and can be reused directly.
Yangjiang's Solvent Extraction Machine can refine all kinds of recycled base oil, vacuum side streams，acid-refined oil, black diesel oil, waste hydraulic oil, waste transformer oil and all kinds of waste mineral oil which don’t contain solid particle to new oil, with watercolor, the color is less than 0.1. The viscosity, viscosity index, acid value, carbon residue, demulsification value, pour point, saturated hydrocarbon of refined base oil can reach or close to the API II standard, like hydrogenated base oil. Also, SR can reduce sulfur from diesel oil to less than 100ppm.
Working Process:
1. Preheating process: heat the feedstock oil in the pre-heating tank to working temperature, keep stirring.
2. First-stage treatment: after preheating, feed the raw material and working solvent to the reactor at the same time, in the reactor, with the special structure, most of the sulfides, oxides, nitrides, colloid, asphalt, arene, unsaturated hydrocarbon can be absorbed by the solvent, then the semi-finished product oil will separate from the solvent and go to the next stage.
3. Recycling of working solvent: working solvent will be recycled by the recycling module (distillation kettle), the adsorptive constituents are distilled out and become sludge oil. The working solvent will be vaporized and go into the condenser as the fluid. At last, the recycled solvent will become the new solvent, in the whole processing, the solvent loss is 0.5%-1%, the cost of solvent for recycling 1000Liters oil is less than USD25.
4. Thin-film evaporator: the SR machine contains a thin-film evaporator, which function is to separate the tiny solvent from oil, it will keep about 2% solvent after five reactors, so we use the thin film evaporator to separate them.

Liquid-Liquid Centrifugal Extractor:
The key step of SR is to separate the solvent from the oil by using the centrifugal extractor
Centrifugal extractor is a new, fast and efficient liquid-liquid extraction and separation equipment. The YJ-SR series solvent refining machine is aimed at the drawbacks of the traditional centrifugal extractor at present. The centrifugal extractor stage has the advantage of short retention time, rapid phase separation, high extraction efficiency, saving investment costs and solvent and regeneration costs.
FAQ:
What our YJ-SR series can do?
It can refine all kind of mineral oil which don’t contain solid particle, such as recycled base oil no matter what color, vacuum side streams, acid-refined oil, diesel oil, black diesel oil, waste hydraulic oil, waste transformer oil, etc.
What quality of oil we can get from YJ-SR?
Refined oil out from YJ-SR with watercolor, the color is less than 0.1. The viscosity, viscosity index, acid value, carbon residue, demulsification value, pour point, saturated hydrocarbon of refined base oil can reach or close to the API II hydrogenated base oil.
How much oil we can get after our YJ-SR solvent refining equipment?
We can get 98-99% refined oil after our YJ-SR; the oil loss rate is only 0.5-1%.
What the difference between our solvent refining equipment and other company`s solvent refining?
Other companies use extraction towers or rotary towers for solvent refining, but we use centrifugal extraction for refining. Our solvent is a Self-developed Composite additive, not a Single additive the general solvent refining only can get the oil with the color standard of 1.0. Our solvent refining can get the oil with the color standard of 0.1.
