Treatment of NORM waste from Oil and Gas industry for final disposal
In 2022 econ industries had taken the responsibility of manufacturing a VacuDry® 1 500 for a client in Saudi Arabia, specially designed for the treatment of various oily NORM waste. The VacuDry® process has been successfully used for the treatment of NORM Waste. The VacuDry® 1 500 is designed to treat ~ 5 t/day of oily soils and sludges contaminated with NORM (Natural Occurring Radioactive Material).
The VacuDry® process recovers oil and water from the NORM waste, leaving the radioactivity in the solid residue. The recovered clean water and clean oil are free of any radioactivity and can be reused. As the remaining solids are free of hydrocarbons, the material can be immobilized using cement or geopolymer and is ready for safe long-term storage in dedicated landfills. Alternatively, the dry solid residue can be transferred into a suspension and pumped back into the wells.
Design characteristics
- Mass & volume reduction of NORM waste
- Separating non-NORM contaminated water, oil and mercury
- Closed system & dust-free operations
- Input flexibility: liquid, pasty, solid—no limitations
- Simplified feeding and discharge system—minimizers residues inside the plant
- Trough chain conveyor for feeding of solids and sludges
- Highest safetty level—due to vacuum process
- Lowest emissions and carbon footprint—due to no use of fossil fuels, vacuum system, and activated carbon filter
