"Regulatory and analyzer update for USEPA's new formaldehyde emissions limit for combustion turbines"

Spectrum's technical team has demonstrated a <27 ppbvd Formaldehyde detection limit (DL) on its extractive FTIR equipped using a 5-meter cell pathlength. This formaldehyde detection is well below USEPA's 91 ppbvd emission threshold for Combustion Turbines now subject to regulation under NESHAP Subpart YYYY. A future field study using a 10-meter cell pathlength and a new detector configuration is anticipated to provide detection limit results on the order of 5 ppbvd or less. Of important note is that all the data, and presented DLs, were collected in a synthetically-generated turbine exhaust gas matrix.
