Oily wastes

The integrated solution for oily wastes

Oil contaminated soil
Oil sludges
Oily wastes
Oil & hydrocarbons
Cleaned solids

Wherever oil is produced, processed, transported or stored, our clients face large amounts of oily waste in many different forms. Our VacuDry® technology allows efficient and environmentally friendly treatment of all oily waste streams within a single plant. Due to the conditions under which the waste is treated (low temperature, vacuum and nitrogen blanketing), the recovered oil can then be reused after treatment.

Benefits of VacuDry® oily waste plants

  • Turn-key, skid-mounted, mobile or stationary custom-made solutions
  • Defined separation of reusable hydrocarbons through gradual heating
  • High operational availability due to self-cleaning dryer
  • High quality recovered oil due to indirect heating under vacuum, no cracking processes
  • Reuse of the condensed, clean water for the re-moistening of treated mineral solid output
  • Emission and dust-free system by encapsulated treatment of exhaust vapours and solids
  • Optional engineering service for mechanical pre-treatment by centrifugation
  • econ VacuDry® system fully meets EN HSE standards
  • Optional: Utilisation of recovered mineral oil fraction for burning inside the thermal oil unit
