Ultrasonic Oxidation Extraction Desulfurization Unit for Deep Sulfur Removal and Oil Upgrading
The VBOLT-TL desulfurization system is designed for diesel, naphtha, kerosene, pyrolysis oil, base oil, and related feedstocks. It combines ultrasonic mixing, controlled oxidation, extraction, and solvent recovery to reduce selected sulfur compounds and support downstream oil upgrading. Achievable sulfur removal and product properties depend on feedstock analysis, process conditions, and laboratory or pilot validation.
Why Choose the VBOLT-TL Desulfurization System
Built for industrial B2B applications requiring deep desulfurization, process stability, lower operating cost, and sustainable refining performance.
Deep Sulfur Removal
Configured for low sulfur targets. Targets below 10 ppm require feedstock characterization and laboratory or pilot validation and are not a universal outlet guarantee.
Feedstock Flexibility
Suitable for diesel, naphtha, kerosene, pyrolysis oil, base oil, and other sulfur-containing oil streams.
Quality Improvement
Improves viscosity index, color, and oxidation stability to support higher-value downstream products.
Integrated Recovery
Supports solvent regeneration and recovery to improve operating economics and environmental performance.
Application Scenario
A complete desulfurization and oil upgrading solution for refineries, petrochemical plants, waste oil recovery projects, and lubricant refining operations.
Designed for Deep Desulfurization and Feedstock Upgrading
The VBOLT-TL desulfurization unit is engineered to oxidize and separate selected sulfur-containing compounds from a wide range of feedstocks. Depending on the feedstock and configured pretreatment and extraction route, it can also reduce certain nitrogen- and oxygen-containing species, gums, and heavy polar contaminants.
Using an application-specific oxidant, catalyst, and extraction package, the system can improve color and oxidation stability while reducing sulfur. Viscosity-index response and any sulfur target, including below 10 ppm, must be confirmed through feed analysis and laboratory or pilot testing.
It is especially suitable for diesel desulfurization, naphtha desulfurization, kerosene desulfurization, pyrolysis oil refining, and base oil upgrading applications.
Waste Oil Recovery Integration
Can be integrated with waste oil recovery units to convert waste oil into valuable reusable resources and reduce environmental impact.
Lubricating Oil Refining Integration
Can be combined with lubricating oil refining systems to support cleaner production and higher-quality lubricant products.
