Mercury Waste Plants for Oil & Gas Industry - Oil, Gas & Refineries

Mercury-contaminated wastes are a major challenge for many industries including the chlorine industry, oil & gas drilling, oil & gas refineries (catalysts) and fluorescent lamps recycling. 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.

  • 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

  • Sources: By-products from industrial processes, mercury as a catalyst e.g. chlor-alkali electrolysis, contaminated sludge from natural gas drilling, oil and gas NORM waste, residues from fungicidal production, wood impregnation, amalgamation, recycled fluorescent tubes, contaminated production sites and building rubble, oil and gas refineries (catalysts)
  • Input material: Sludges with varying viscosities, powders, soil, adsorbents, catalysts, sediments, building rubble
  • Output material: Pure liquid mercury (> 97 %, 99.999 % possible), water, solid output with Hg concentrations below 10 ppm, 1 ppm possible
  • Plant design: Fixed or mobile execution 0.5 … > 10 t/h throughput capacity
  • Heating system fired by: Fuel oil, diesel, natural gas, electricity, biofuels, recovered mineral oil fraction
