10ppm S% Low Sulfur Diesel Desulfurization Plant Continuous Distillation
Produce Low Sulfur Content Diesel Continuous Distillation Diesel Desulfurization Process
Product Description of Diesel Desulfurization Process
PPGT oil extraction and desulfurization plant is carried out to efficiently remove poly aromatic hydrocarbons, sulfur-containing compounds, colloids and asphaltenes for diesel from cracking distillation streams or pyrolysis. It adopts PurePath exclusive technology combining with ultrosound and hydrocavitation to enhance the desulfurization oxidation reaction. It's 10-20 times desulfurization ability than ordinary silica gel refining or desulfurization catalyst. It could produce water color diesel from dark or red diesel, meanwhile the desulfurization diesel is with optimal oxidation stability which could even store 6 months without color change.

Highlights of Diesel Desulfurization Process
- 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.
