Optimizing VOC Combustion - Case Study


Volatile Organic Compounds (VOCs) are pre-cursors to Ozone pollution and subject to EPA regulations. Thermal and catalytic oxidizers are routinely used to destroy VOC emissions from a variety of industrial sources.

NOx and CO are common byproducts created in the burning of natural gas.  All of these pollutants can be effectively minimized, but the challenge is engineering a solution that has to work within constraints of an existing system while remaining cost effective to operate.

We wanted to share the story of how we were able to help one of our clients find a cost effective solution to new emission regulations:

Case Study

A tape manufacturer in California contacted us when challenging low emission standards were put into place by the South Coast Air Quality Management District (SCAQMD).  

In this client’s case, their thermal oxidizer had been in service for almost 10 years with great success. New emission regulations enacted by SCAQMD required the client to lower the emissions byproducts in order to obtain the appropriate operating permits. 

After evaluating the system, CPI's engineers determined that the oxidizer could be retrofitted with a new low NOx combustion system that operated at a higher temperature, which would result in greater destruction of CO.

The Results

  • The client saved nearly one million dollars by avoiding the purchase and installation of a new thermal oxidizer.
  • A Reduction in lead time for compliance from 8 months to 3 months.
  • VOC destruction was increased from 98% DRE to 99.3% DRE.
  • NOx emissions were certified to less than 60 ppmv.
  • CO emissions were certified to less than 20 ppmv.
