Volatile Organic Compounds (VOC)

VOC emissions are currently issued into the atmosphere in a large number of production processes that use organic substances in several industries, such as Chemical, Pharmaceutical, Petrochemical, Automotive, Flexoprinting, Oil & Gas, etc. Current EU and national legislations establish maximum VOC emission limits for the various production processes affected.

  • VOC emissions are one of the biggest environmental problems for many Industries nowadays
  • Global warming generated by VOC emissions is 12 times higher than that produced by CO2
  • VOC emissions are regulated by EU Directive 1999/13/CE

VAM (Ventilation Air Methane) Treatment in Coal Mines

Coal extraction requires forced ventilation in mine galleries to evacuate the methane toward the exterior to make air quality healthy for workers. That mine air contains large quantities of methane that must be treated before being issued into the atmosphere.

The best technology to treat VAM (Ventilation Air Methane) is Regenerative Thermal Oxidation (RTO). The oxidation process is used to break down the CH4 into CO2, thus obtaining a performance of 99.9% methane destruction.

RTO technology allows taking advantage of the energy required for methane oxidation to perform cogeneration. Through heat exchangers energy is used to be transformed into steam, electricity or hot water.

Methane Emission in Landfills

Currently, municipal waste landfills have large emissions of methane. The use of torches to burn off methane at each one of the sources is the cheapest technology when the landfill has few sources. When the number of sources of methane emission is greater, the most appropriate technology to treat them all at the same time is Regenerative Thermal Oxidation (RTO). This technology may be adapted to gas flows to be treated from low flow to very high low flow, with a much lower operating cost than conventional torches. It is the methane itself that generates temperature within the oxidiser and thus a full oxidation is achieved.

The great advantage of using RTO on a landfill with several emission sources lies in the acquisition cost being similar to or lower than the cost of torches. It also allows taking advantage of the energy generated by oxidation for subsequent use through heat exchangers. All these benefits are achieved with a very low operating cost.

Active Carbon Filters – “The Solution for Intermittent Processes”

Active carbon filters are suitable for minimising VOC emissions in intermittent processes as well as for odour treatment. This technology works through an absorption process. The absorbent property consists of a physical phenomenon in which a solid, called absorbent, traps certain types of molecules in its pores, called absorbates, that are contained in a liquid or a gas.

Tecam Group offers Active Carbon Filters for VOC emission treatment.
