YJ-SR 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 water color, 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 50ppm.
the main part of SR is Centrifugal extractor(like following picture),which can react and separate the oil and solvent quickly:
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 threw 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 separation zone that composed of heavy phase enthalpy.
1.What’s the function of solvent extraction machine
It can increase the oil quality,you can only get Group I base oil after distillation, but the solvent extraction machine can make the oil to Group II.
Reduce sulfur to 50-100ppm
2.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 loss rate is only 1-2%.
3.what’s the solvent loss
There is solvent recovery on our machine, which can recycle the used solvent to new and reused again and again, solvent loss is 0.5%-1%.
4.what the difference between our solvent refining equipment and other company`s solvent refining?
5.Compare with hydrogenation system
Normally Hydrogenation system is installed for big project,more than 400-500Ton per day, the investment of hydrogenation is high.
6.Warranted?
-Yangjiang promise the machine is 100% brand new, we will provide 12 months quality guaranty from the time machine starts running at the buyer’s site.
7.Installation and training:
-Yangjiang provide 20-30days free installation and training.we will dispatch 1-2 engineers go to buyer’s factory for installation, testing and commissioning the machine, also train or provide any other technical assistance.all expenses for visa, accommodation, round-trip air ticket and lodging shall be borne by the Buyer
8.What the difference between our solvent refining equipment and other company`s solvent refining?
Other companies use Extraction tower or rotary towers for solvent refining, but we use centrifugal extraction for refining. Our
solvent is Self-developed Composite additive not 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.
