This paper presents a tunable laser analyzer that has the capability to analyze several components in a gas sample stream. More specifically, a multi-gas system for simultaneous detection of C1-iC5 hydrocarbons, using a room temperature distributed feedback (DFB) inter-band cascade laser (ICL) array, emitting in the 3.3-micron band has been realized. It combines all the advantages of the tunable laser spectroscopy method for a fast, sensitive and selective in-line multicomponent tunable laser analyzer. Capable of continuous monitoring of C1-iC5 hydrocarbon compositions in a process stream, the analyzer requires no consumables (e.g., purging, carrier gas) and no in-field calibration, bringing the overall cost of ownership down.
The system was built on an industrial GasEye series platform and deployed for a first time in field at Preem refinery in Lysekil, Sweden in autumn 2018. Results of the measurement campaign and comparison with gas chromatography instrumentation is presented.
Pawel Kluczynski obtained his Master degree in 1997 in Physics and his Ph.D. degree in 2002 in a field of laser spectroscopy. He started his research with tunable laser spectroscopy methods in 1997 developing algorithms for data processing. He is an author of more than 20 scientific papers and inventor of 14 granted patents in the field of tunable laser gas analyzers. In 2001-2010 he has been working with design and arcgitecture of tunable laser gas analyzers at Siemens. He founded Airoptic in 2010. He has been the CEO of the company since 2010.
