As the full effect of the Federal Clean Air Act (CAA) Amendments continue to impact today’s industry, many different companies will be required to install air pollution control equipment. With more than twenty-five years of proven success, catalytic oxidation continues to be a popular method for controlling volatile organic compound (VOC) emissions. According to the Clean Air Act, any organic compound that contains the element carbon(excluding carbon monoxide, carbon dioxide, carbonic acid and methane) is a VOC, and at various emission levels,must be controlled.VOCs consist of a variety of organic compounds such as aliphatic and aromatic hydrocarbons, alcohols, ketones, esters, ethers, formaldehyde and many others. Emissions from stationary sources containing VOCs contribute to the air quality problems that adversely affect the public health and welfare. Uncontrolled VOC emissions combine with NOx and in the presence of ultraviolet radiation, produce ground-level ozone. Certain VOCs are now also classified as air toxics or Hazardous Air Pollutants (HAPs) that pose special health risks.
