Condensation and Exhaust Air Treatment Systems
topic
Stenter exhaust air treatment systems remove textile finishing chemical vapours, aerosols, and oligomers from hot exhaust air through thermal oxidation at 700 to 800 degrees Celsius, condensation filters, or electrostatic precipitators before atmospheric discharge, meeting industrial VOC emission limit values and preventing stenter exhaust deposits on surrounding building surfaces that create environmental and fire hazard risks from accumulated condensed finishing chemical residues.
Role
Addresses the air quality and environmental compliance obligations of textile finishing operations by treating stenter exhaust air before atmospheric discharge to remove organic compounds and aerosols that would violate ambient air quality regulations and cause nuisance odour to surrounding residential areas, with thermal oxidation being the most effective but energy-intensive treatment method and condensation systems offering lower energy consumption for facilities with lower VOC emission levels.
