A Midwest candy manufacturer will utilize a catalytic oxidizer for the abatement of volatile organic compounds (VOCs). The 2,000-scfm unit, supplied by Catalytic Products International (CPI), will control the VOC emissions from the application of an alcohol-based confectioners glaze from an extrusion line, dip bath and flash-off area. It will destroy VOC emissions from the process with 98 percent destruction efficiency.
Coating edible products such as candy often utilizes a dip-bath process in which the edible product is coated with an alcohol-based confectioner’s glaze. During the application and drying of this glaze, significant emissions of VOCs are released into the environment.
Catalytic treatment of VOCs and other air pollutants works by reacting the harmful air pollutants over a specially designed catalyst where VOCs are converted to CO2, water vapor (H2O) and usable heat. The byproducts are passed through a heat exchanger, where the gas stream’s energy is transferred to the incoming exhaust. CPI’s system can deliver the highest temperature uniformity before the catalyst bed and ensure that all of the catalyst is efficiently oxidizing the VOCs, says the company.
