The catalytic oxidizer in this system is designed to oxidize more than 98% of both standard VOCs and chlorinated compounds. As a result of the oxidation of the chlorinated compound, HCI is formed and must be treated prior to being exhausted to the atmosphere. The formation of HCI in this application facilitates the need for an integrated quench / scrubber system.

While the water quench neutralizes some of the acid from the catalytic oxidizer, its main function is to reduce exiting air temperature from the oxidizer to 140 degrees F prior to entering the scrubber. A sodium hydroxide solution is circulated through the packed bed scrubber to remove and neutralize up to 99.9% of the acid gases. Met-Pro's integrated systems include automated metering of caustic solution and pH monitoring of discharge water. A final mist eliminator removes remaining aerosols.
