Regenerative thermal oxidation allows you to destroy the voc’s with a high degree of thermal efficiency by using ceramic media to accumulate and release heat rapidly. The plant usually comprises three canisters containing ceramic media but, in the cases of high airflow multiple canisters, (5 or more), can be used. A hot side, high solvent bypasses can be used when high voc concentrations are present to dispose of any excess heat. However, we have also developed specific solutions which are ideal for treating emissions with low voc concentrations such as two canisters with storage or buffer tank system where appropriate.
Solvent recovery occurs as the pollutant contained in the gaseous emission is transferred to an adsorbing material such as activated carbon, (adsorption), and then removed from it by means of a hot fluid (regeneration). Where solvents are not soluble in water, steam regeneration is actually preferred, because it can be condensed, cooled and separated from the solvent to be recovered more easily. In case of water soluble or partially soluble pollutants regeneration occurs using an inert gas (usually nitrogen) which is cooled by condensing the solvent to be recovered. Plants are equipped with auxiliary systems for: The treatment of condensate; The reduction of steam consumption (economizer); The dehydration of recovered solvent; The distillation of recovered solvents.
BROFIND plays a leading role in the environmental industry, offering a comprehensive range of technologies for air purification to a wide range of industries, with special attention to the problems of gaseous emissions containing Volatile Organic Compounds (VOC).
BROFIND was founded in 1993 by a group of professional engineers with over twenty five years experience in the field of pollution control and atmospheric emission treatment.
