Tank cleaning / tank service

The history of the Rohrer Group began more than 40 years ago with their first contracts in tank cleaning. Since then, the performance has constantly increased by means of innovations and the use of modern technologies. This enabled the company to develop into one of the best known and most competent supplier of tank cleaning in the chemistry and the petrochemistry.

  • Crude oil tanks
  • Heavy oil tanks
  • Fuel and naphtha tanks
  • Tanks for finished products
  • Slop tanks
  • The turbomix procedure which has been used and constantly enhanced by the Rohrer Group is one of the most efficient tank cleaning procedures available on the market. Powerful, hydraulically driven mixers with controllable rotors are installed into the floating roof manholes of the tanks.

  • The oil sludge occurring during the course of the tank cleaning or in the production plants are separated into their components by means of decanter or tricanter® centrifuges from the company Flottweg.

    Decanter separate oil sludge in two phases, a liquid phase (mixture of oil and water) and a dry sediment phase.

    During the separation with the more complex tricanter® centrifuges, there are three phases (oil, water and sediment) with very little portions of the corresponding undesired foreign substances. The resulting separated products can be reused and / or disposed of partly without further treatment.

     

  • The existing plants are available in different sizes and designs with all necessary accessories. The use of the mobile torching facilities allows for the creation and secure maintenance of the limit values for driving into containers, tanks and units.

     

  • The Rohrer Group offers its customers no-man-entry systems for tank cleaning in the module system. For this purpose, both in-house systems and systems available on the market are used as modules in combination.
