The abatement of carbon monoxide (CO) and the oxidation of organic substances (TOC and VOC) can be thermal or catalytic. Area Impianti can supply modern catalytic methods, integrated in processes with DeNOx – DeDIOX modules or, if required, thermal oxidisers.
These systems are used in the chemical industry, in incinerators, in diesel engines (including vegetable oil) and in any process where the conditions for complete combustion are not optimal.
The process for the abatement of CO and organic substances is an exothermic oxidation that converts these compounds into CO2 and water. This process can also improve the efficiency of unburned dust removal. Thermal combustion takes place at minimum 700°C for CO and 800-900°C for more complex compounds. However, with the use of catalysts, these temperatures can be reduced to 200°C for CO and 200-400°C for more complex compounds.
Operating temperatures are achieved with:
- Self-support, thanks to the heat generated by the exothermic reaction.
- Heat exchangers, recuperators and burners.
- Thermal capacity of two or more catalytic modules in a regenerative thermal oxidiser.
