Faced with meeting the needs of their Pharmaceutical Industry MACT Standards, one Fortune 100 Pharmaceutical Manufacturer called on CPI for assistance. The challenge for Catalytic Products International was to design a system that was able to process the ultra-high LEL (high concentration of VOC’s) and deal with corrosive acids produced in the process off gas and the post-combustion gases. Adding to the challenge, there were many more sources that use halogenated VOC’s in the process. A halogenated VOC is an organic hydro-carbon that contains chlorine (Cl). The post combustion gases will contain Hydrochloric Acid. In order to meet the needs of local regulations and the industry MACT, the HCl also has to be removed from the exhaust stream prior to atmospheric release.
