White oils are highly refined mineral oils that are extremely pure, stable, colorless, odorless, non-toxic and chemically inert.The term “white oil” is a misnomer, in that they are not white at all, but crystal clear. White oils can be produced from a variety of feedstocks, depending on the process used. These starting materials include conventional base stocks for the older acid treatment process to Vacuum Gas Oils (VGO) for the more currently widely used two stage hydrotreating method.but acid treatment has serious environmental pollution, and hydrotreating with high cost, so now our company provide a new method,which refine the oil to white oil by adding catalyst solvent, it can produce colorless, odorless, tasteless oils where all components that might have any detrimental effects on their end usage, such as aromatics, sulphur or other impurities, have essentially been removed, resulting in a pure and thermally stable product. 

Question and answer

What our YJ-SR solvent extration plant can do?

The YJ-SR series solvent refining 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 hydrogenated base oil, also this machine can remove sulfur from diesel oil to 50-100ppm

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%.

what the difference between our solvent refining equipment and other company`s solvent refining?


  1. Other companies use Extraction tower or rotary towers for solvent refining,but We use centrifugal extraction for refining.
  2. Our solvent is Self-developed Composite additive not Single additive
  3. 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.
