Company File
PurePath Green Technology designs and manufactures complete, turnkey, skid mounted systems which is used to upgrade lubricants, fuel oils and other hydrocarbon compounds to premium. PPGT-UC-SDS as the Purepath's main oil desulfurization &refining equipment, it combines a variety of leading edge technologies such as hydraulic cavitation enhancing reaction effect, ultrasonic oxidation increasing desulfurization ratio, complexing centrifugal extraction and packing type distillation column ensuring solvent recovery accuracy and efficiency etc..
PPGT-UC-SDS is carried out to efficiently remove poly aromatic hydrocarbons, sulfur-containing compounds, colloids and asphaltenes from the feed stock to improve viscosity index, color, oxidation stability through the action of PPGT provided composite extracting agent. Especially for the refining of base oil and diesel oil, refined base oil will be closed to API II standard with water color; refined diesel will be API standard commercial diesel fuel with less than 50ppm of sulphur content and water color which could be used for high speed diesel engines/vehicles directly.

Highlights of Diesel Fuel Polishing System
- PurePath exclusive technology ultrosound and cavitation desulfurization process could remove as high as 97.5~98.5% sulfur content for diesel.
- No secondary pollutes for environment: no waste generated during desulfurization process.
- Low cost of manpower: Siemens PLC/SCADA control to ensure the automation and continuously operation.
- Fractional distillation make sure 98~99% used solvent could be recycling use.
- Polished oil is less than 0.5 ASTM color scale like water color.
- US$12~US$20 of solvent consumption to desulfurization for 1 ton feed oil.
