Field evaluation of a multi-component FTIR CEMS against PS-15, PS-18, and procedure 6

A major U.S. cement manufacturing facility completed a five month field trial of a hot/wet extractive FTIR CEMS in August 2015. The system was evaluated on the basis of its capabilities to satisfy HCI emission monitoring requirements under 40CFR63 Subpart LLL (also known as "PC MACT") as well as monitoring other pollutants and parameters (SO

). A fundamental objective was to determine if the system could meet the initial CEMS certification and on-going QA requirements in both Performanc Specification 15 and Appendix F, Procedure 1 and Performance Specification 18 and Procedure 6. Of particular interest was the ability to use optical filters and internal gas cells for automated daily calibration checks of criteria pollutants, and potentially for HCI measurements, as this may greatly reduce the need to rely on external compressed gas standards, except for periodic audits.
