Manufacture of chlorinated hydrocarbon (RCI) based products includes treating the associated waste streams. On the basis of “Best-Available-Technology, ”waste disposal is generally accomplished using vent incinerators (thermal oxidizers). Vent incineration may lead to the formation of undesirable Products of Incomplete Combustion (PIC's). The recent Boiler & Industrial Furnace (BIF) regulations have required that companies certify the ability of their Thermal Oxidizers (TOXs) to meet these new emissions* regulations.
