Abstract Information :
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.
