Laser Spectroscopic Multi-component Hydrocarbon Analyzer

摘要

Yokogawa has developed a prototype of a laser spectroscopic multi-component hydrocarbon analyzer, which can measure the components simultaneously, precisely and rapidly. This analyzer uses a semiconductor laser with a widely tunable wavelength range called micro electro mechanical systems-vertical cavity surface emitting laser (MEMS-VCSEL), and a newly developed spectrum analysis algorithm. This can be applied to the real-time process control. Yokogawa has conducted a field test for measuring the calorific value of the process gas in a calorie adjustment process of town gas as one of its applications. This report outlines this analyzer and introduces the results of the field test.
