Comparison of HAPs and hydrocarbon emissions

摘要

The proposed hazardous waste combustor (HWC) maximum achievable control technology (MACT) rule published in the April 19, 1996, Federal Register requested data and information on monitoring carbon monoxide (CO) or hydrocarbon (HC) emissions to control organic hazardous air pollutants (HAPs) emissions. The preamble of the proposed rule further states that monitoring HC emissions can also ensure that sources operate under "good combustion conditions." As a result, the proposed rule is attempting to monitor organic HAP emissions as well as emissions from incomplete combustion (PICs). Because a large fraction of HAPs are organic compounds, using HC as an indicator for HAP emissions warrants further investigation. However, using HC as an indicator of PICs or good combustion is inconceivable bacause HC and PIC compound emission depend on other process variables not related to hazardous waste fuel combustion completeness. The available database of HC, and volatile and semi-volatile organic HAP emissions indicates that HC-HAP correlations are difficult to make and HC-PIC emissions are non-existen.
