Abstract
A gas analysis system and method using a spectrometer, such as a Fourier transform infrared spectrometer, utilizes a reactor, such as a catalytic reactor, for providing interference spectra. The gas is pressurized and chilled to remove water prior to the spectrometer.
Claims21
A gas analysis system, comprising:
- a spectrometer configured to analyze gas;
- a reaction device configured to selectively provide a sample stream or a reacted sample stream to the spectrometer, wherein the reacted sample is stream is provided by removing at least an analyte of interest from the sample stream;
- a system configured to provide the sample stream by reducing water in the gas upstream of the reaction device, wherein reducing water in the gas includes pressuring and then cooling the gas, and wherein providing the sample stream further comprising reducing a pressure of the gas after reducing water in the gas;
- and
- a controller configured to use the reacted sample stream to create spectra for analyzing the sample stream.
