Complete upstream planning – from reception and separation to dewatering, feeding into our VacuDry® – indirect heated vacuum distillation process.
The treatment of oily waste and sludge is a complex task that requires precise coordination of mechanical and sustainable thermal processes. At econ industries, we not only supply the VacuDry® system, but also plan and integrate the surrounding process steps – such as waste handling, classification, and dewatering – to ensure a complete and efficient plant design.
Our upstream solution starts with reception, classification, mechanical dewatering, typically using a high-performance centrifuge or other suitable separation technologies. Effective dewatering removes free water and oil, significantly reducing the treatment volume of the VacuDry® plant. This step not only lowers the energy demand in the following thermal process but also increases the total capacity of the facility.
Smart facility planning – built around your needs
Each project begins with a detailed assessment of the waste streams, followed by the creation of a modular layout. Our team of experts specializes in integrating advanced recycling technologies into full facilities to create optimal hazardous waste management concepts.
This Facility allows for maximum flexibility depending on the client’s site conditions, waste characteristics, and recovery goals.
Our dynamic planning approach allows for:
- Efficient layout integration in limited spaces
- Adaptable capacity – from small mobile systems to large-scale installations
- Future expansion possibilities (e.g. adding mercury waste treatment or NORM handling)
- Optimized flow between process steps to reduce manual handling and increase automation
Process steps in a typical econ industries plant:
- Reception of oily sludge
Trucks or pipelines unload into feed tanks, buffer containers or pits. - Centrifuge dewatering
Solids and water are separated to reduce moisture content before thermal processing. - VacuDry® – vacuum thermal desorption process
At 50 mbar(abs) and moderate temperatures up to 400 °C, hydrocarbons are evaporated and later condensed in the highest quality. - Oil and water recovery
Valuable oils and clean water are separated and can be reused. - Safe handling of solids
Clean, dry mineral residues are discharged – free from hydrocarbons with a TPH content of below 0.5 %. - Optional modules
Wastewater treatment, Mercury stabilization by MMCU, or other packaging units can be integrated depending on project needs.
Thanks to the synergy of centrifugal dewatering and VacuDry® vacuum-based thermal separation, our concept approaches offer a robust and sustainable solution for refinery sludge, tank bottom sludge, drill cuttings and more.
With econ industries hazardous waste management competence team, you can ensure that your oily wastes is transformed into valuable outputs, safely and efficiently. We are accelerating project realizations and ensure successful implementations.
