Oil-Contaminated Soil Treatment: Advanced Thermal Washing Solutions
Learn how Desen Environment's oil-contaminated soil washing equipment uses thermal washing technology to recover oil, reduce waste, and restore polluted land. Explore our proven remediation system.
The Growing Challenge of Oil-Contaminated Soil
Oil spills, drilling operations, and petroleum storage leaks generate vast quantities of oil-contaminated soil that require professional treatment. Crude oil, diesel, and other petroleum hydrocarbons bind tightly to soil particles, creating a complex remediation challenge. Without proper treatment, these contaminants can leach into groundwater and cause long-term environmental damage.
Desen's Thermal Washing Approach
Desen Environment has developed a specialized oil-contaminated soil washing equipment (DSLX series) that employs thermal washing technology combined with chemical extraction. The process begins with pre-screening and crushing of contaminated soil, followed by high-intensity scrubbing in a rotary drum washer where heated water and specialized washing agents break down the oil-soil bonds.
The complete treatment chain includes: high-efficiency rotary drum scrubbing, multi-stage classification at 2mm and 0.15mm thresholds, integrated oil-water separation, plate-frame filter press dewatering, and advanced oxidation water treatment with over 90% recycling.
Proven Performance Across Oil Sites
Desen's oil washing system has demonstrated exceptional results treating soils with petroleum hydrocarbon concentrations up to 50,000 mg/kg. The equipment has been deployed at oilfield drilling sites, abandoned gas stations, petrochemical plant legacy sites, and storage tank leakage areas. With 15-100 tons per hour capacity and modular configuration, the system adapts to projects of any scale.
Sustainable Remediation with Measurable Results
By combining thermal oil-contaminated soil washing with intelligent DCS control and 5G remote monitoring, Desen Environment delivers remediation projects that are both environmentally responsible and operationally efficient\u2014making it the trusted partner for oilfield service companies and environmental agencies worldwide.
