SERVOTOUGH SpectraScan 2400 - A tunable filter optical system for on-line and real-time hydrocarbon gas composition analysis

Abstract

An all-optical sensor platform has been developed for hydrocarbon gas composition analysis enabling speciation and quantification of the individual hydrocarbon components in multi-component matrices of alkanes, alkynes, alkenes and/or alcohols. It performs such speciation without requiring physical separation of the compounds as performed in chromatography. The flow-through optical sensor provides unattended, real-time and consumable-free analysis suitable for on-line fuel gas analysis, combustion control, pipeline gas quality monitoring, BTU/heating value measurement and various hydrocarbon processing applications.
