Show C O N C L U S I ON The Clean air Act Amendments of 1990 made several significant changes in the Clean Air program which will impact operation of chemical and petrochemical facilities. In general, those sources which emit 100 tons per year of any air pollutant, 10 tons per year of any individual hazardous air pollutant, or 25 tons per year of any combination of hazardous air pollutants, or any source subject to the non-attainment provisions will be affected by the new law. Those sources which fall into this category will be required to demonstrate at least 9 0 % control for hazardous air pollutants or demonstrate that "maximum achievable control technologies" ( M A C T ) as defined by the U.S. E P A are being utilized (8). For non-attainment areas, the new law contains provisions to regulate sources of NOi,, VOCs, CO, and particulate matter that have previously escaped emission controls. Under the Clean Air Act Amendments of 1990, the E P A must determine and classify into five discreet categories areas which do not meet National Ambient Air Quality Standards for ozone. Depending on the severity of the ozone problem, each category will have a series of progressive and more restrictive set of emission controls. This provision of the Clean Air Act Amendments will require offsets for new or expanded sources in addition to control technologies that meet lowest achievable emission rate (LAER). The new law will have a severe impact on sources that emit hazardous air pollutants that are compounds which contain bound nitrogen. Control technologies for these applications must achieve maximum destruction efficiencies with minimum N O, formation. The Hybrid Low NO, Process can achieve both objectives. By combining thermal and catalytic treatment steps, this technology can achieve destruction efficiencies in excess of 99.9%, while controlling N O , emissions to levels below 25 ppmv and C O emissions below 50 ppmv. This represents a substantial improvement over current technologies that use staged combustion techniques. 8 HI-16 |
