Formaldehyde FTIR Measurement

Reciprocating internal combustion engines burning natural gas are a source of formaldehyde emissions. There are strict tolerances imposed on operators of engines to ensure that formaldehyde is removed effectively and that formaldehyde emissions are below published limits.

The only instrumental method for formaldehyde monitoring is FTIR, following procedures such as US EPA Method 320 and Environment Agency TGN M22. Protea’s FTIR gas analysers have been specifically designed to follow these methods and our FTIR analyser have been proven in formaldehyde emission measurements over many years.

FTIR formaldehyde monitoring requires extreme care and quality assurance at the calibration stage. Traceable formaldehyde standards are as easily available as other gases and Protea has done a lot of work in proving our calibrations are valid, with technical studies completed on theoretical spectra from the HITRAN database as well as comparative testing against manual methods for aldehyde analysis.

Accurate formaldehyde monitoring can be carried out on both our transportable FTIR as well as fixed continuous emissions systems (CEMs) for formaldehyde. With Protea advanced data processing software, data collected in the field can be re-processed for formaldehyde months or years after the data has been collected.
