treatment of Gaseous Emissions

Thermal Combustors

Applications:

Elimination of volatile organic compounds (VOC’s) through high temperature thermal oxidation.

Features:

  • High thermal recovery efficiency, with reduced or eliminated auxiliary fuel consumption
  • Possibility of several chambers according to the volume to be treated

Catalytic Combustors

Applications:

Elimination of volatile organic compounds (VOC’s) using high-performance metal-based or precious metal catalysts. One of the applications of this technology is the elimination of NOx from the emissions of internal combustion engines in cogeneration systems, powered by diesel or biofuels such as biodiesel and vegetable oils.

Features:

  • Use of lower temperatures in the combustion of organic contaminants
  • Different configurations possible. The catalyst material can be installed in pellet or honeycomb form
  • Possibility of integrating a heat exchanger to take advantage of the thermal energy contained in the exhaust stream

Rotoconcentrators

Applications:

Concentration of high flow streams containing low amounts of volatile organic compounds (VOC’s).

Features:

  • Reduction of 10 to 15 times the flow rate to be treated in the thermal oxidation system, proportionally increasing the concentration of volatile organic compounds (VOC’s)

Aluminum Rolling Mill Oil Reclaimers

Applications:

Control of oil mist emissions and recovery of lube oil and coolant.

Features:

  • Combination of treatment of oil mist laden exhaust air from aluminum foil mills with recovery of the oil itself
  • Oil treatment in a scrubber and subsequent feed to a distillation column for separation of lube oil and coolant

Adsorption on Activated Carbon

Applications:

Removal/adsorption of volatile organic compounds (VOC’s) from process gas streams.

Features:

  • Adsorption occurs through surface interaction between the contaminants and the charcoal surface.
  • Systems with or without regeneration
