Treatment of hydrocarbon contaminated soils and wastes

A waste management company from Australia was looking for an environmentally friendly solution for oily waste with low emissions and a low carbon foot print. To save installation and commissioning time econ realized a pre-installed modular VacuDry® plant. The plant is designed for maximum flexibility and it is able to treat different types of refinery waste ranging from dry soil to wet centrifuge cake.

The VacuDry®plant is equipped with two VacuDry®12 000 evaporators. The input material mainly contains diverse hydrocarbon fractions from various sources. After separation the recovered oil can be sold to the refinery or it can be reused. The cleaned mineral residues have a hydrocarbon concentration (C6-C36) of less than 0.5 percent.

Design Characteristics

  • Designed for hydrocarbon contaminated soil and sludge
  • Separation of hydrocarbons for reutilisation
  • Specially designed high temperature discharge system for accelerated batch times
  • Redundant vacuum and cooling water system for highest plant availability
  • Emission and dust free system through encapsulated treatment of exhaust vapours and solid material
  • Plant fulfills ATEX requirements for Zone 2 operation
