Formation and release of methanol and hydrogen chloride from DCE recovery boiler systems

The 1990 Amendments to the U.S. Clean Air Act require the regulation of hazardous air pollutants (HAPs). The combined system of air-blow black liquor oxidation and recovery boilers with direct-contact evaporators and wet-bottom precipitators constitutes one of the major sources of HAP emissions in a...

Description
Summary:The 1990 Amendments to the U.S. Clean Air Act require the regulation of hazardous air pollutants (HAPs). The combined system of air-blow black liquor oxidation and recovery boilers with direct-contact evaporators and wet-bottom precipitators constitutes one of the major sources of HAP emissions in a pulp and paper mill. This paper summarizes the results of laboratory studies and field tests to investigate the formation, release, and destruction of HAP compounds, particularly methanol and hydrogen chloride, in recovery boiler systems with direct-contact evaporators.
