摘要

Abstract: The objective of the work presented here was to develop a technology for continuous measurement of stack gas emissions for compounds such as HCl, SO$-2$/, and NO$-x$/ that was also capable of monitoring toxic hydrocarbons. The goal was to assure operators and local communities that the emission source is routinely operating in compliance with and well within the U.S. Environmental Protection Agency guidelines. A mass spectrometer-based continuous emissions monitoring system (CEMS) and its sample extraction system developed as a result of this work are described. Results of calibration drift, linearity, and accuracy tests for HCl, SO$-2$/, and NO$-x$/ are presented. Results of CEMS tests are described that show the system has the performance capabilities necessary for a relatively inexpensive and frequent DRE demonstration. !8
