Water-Free Sand Treatment Technology for Fuel Oil Removal
A solvent-based sand treatment technology enables efficient removal of fuel oil contamination without the use of water. The process is designed to achieve residual petroleum product content of 5 mg/kg ±40%, meeting environmental and regulatory requirements.
Technology Overview
The solution is based on treating fuel oil–contaminated sand using organic solvents, ensuring effective separation of hydrocarbons from solid particles.
Key objective
- Reduce fuel oil content in sand to 5 mg/kg ±40%
Core principles
- Water-free process
- Controlled solvent treatment
- Analytical verification before and after treatment
- Additional post-treatment if required to reach target values
The treatment process includes the following steps
Collection of contaminated sand samples
Laboratory analysis of untreated material
Preparation of sand and uniform distribution of fuel oil
Treatment with organic solvents
Removal of solvent after processing
Post-treatment sampling and analysis
Additional treatment cycles if required
Storage of treated samples until results are confirmed
- ↓ From 6800 ppm to <5 ppmPetroleum products
- ↓ From 6 to <1Benzo[a]pyrene
The treatment technology is validated as effective based on achieving residual petroleum content within 5 mg/kg (ppm) ±40%.
This enables its application for environmental remediation of oil-contaminated sand in industrial and coastal areas.
