Mercury-contaminated waste is a major challenge for many industries including the chlorine, oil & gas refineries (catalysts) and oil & gas (drilling) industries. Due to strict legal restrictions and HSE requirements, mercury-contaminated waste is required to be handled with special care. We at econ industries have the best solution for each specific mercury waste stream, with plants that are recognised as being state of the art from approval authorities worldwide.
Benefits of VacuDry® mercury waste plants:
- Environmentally friendly recovery of reusable mercury
- Separately recovered contaminants by fractional condensation
- High temperatures and low vacuum ensure an thorough cleaning process
- Low energy consumption
- Small off-gas stream – no expensive downstream exhaust gas treatment required
- Emission and dust-free system; encapsulated treatment of exhaust vapours and solids
- Suitable for treatment of NORM (Natural Occurring Radioactive Material) waste
