MASS SPECTROMETER-BASED CONTINUOUS EMISSIONS MONITORING SYSTEM FOR HAZARDOUS WASTE STACK GAS MEASUREMENTS

摘要

Disclosed is a continuous emissions monitoring system for exhaust gas emissions containing HCl comprising a sampling subsystem with a sample probe in the effluent to collect effluent samples that are transmitted through heated conduits through one or more filters and pumps to a mass spectrometer. The sampling subsystem is maintained at a temperature no less than about 190 DEG C. and the flow rate through the-system is greater than about 10 liters per minute. The process for continuous monitoring of exhaust emissions containing HCl extracts an exhaust gas sample and maintains the temperature and physical state of the exhaust gas throughout transport of the sample from the exhaust effluent to a mass spectrometer.
