An Optical Hydrocarbon Analyzer for Real-Time Hydrocarbon Gas Speciation and Measurement

摘要

A unique all-optical, real-time, unattended sensor platform has been developed for hydrocarbon gas composition analysis enabling speciation and quantification of the individual light hydrocarbon components such as C1 - nC6 of alkanes, high- range hydrogen sulfide, and carbon dioxide. This all-optical sensor performs real-time speciation without requiring physical separation of the compounds as performed in traditional chromatography. Moreover the ability to offer fast, accurate and repeatable C1 - C6 total BTU/HHV for natural gas pipeline energy content monitoring can be proven side-by-side with traditional gas chromatograph methods.
