Larger Capacity Customized Diesel And Fuel Oil Desulfurization System For FFC
Product Description of Diesel And Fuel Oil Desulfurization System
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 UC technology 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.

Features of PurePath Diesel And Fuel Oil Desulfurization System
PPGT UODS as an alternative Hydrogenation Treatment fuel oil desulfurization process offers significant advantages. Thiophene, substituted benzo- and dibenzothiophene are oxidized at low temperature and low pressure. Therefore, expensive hydrogen is not required, making the process more suitable for small and medium-sized Refineries or isolated refineries not close to hydrogen pipelines. The increased reaction rate and mild reaction temperature and pressure avoid the use of expensive anhydrous or aprotic solvents. Ultrasonic assisted oxidative desulfurization (UAODS) unit can produce low sulfur and / or ultra-low sulfur diesel. This technology can be used to reduce sulfur content before or after FFC fuel oil or atmos distillation diesel and pyrolysis oil. Compared with the new high-pressure hydrotreating unit, the UAODS process can reduce the estimated capital cost by more than half and get the same result for end product.
Company Profile
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.
