Abstract:
On-line process measurement of the composition of gas streams in refining, ammonia, and methanol plants is essential for the optimal operation of different process units within these facilities. Process analyzers based on gas chromatography, mass spectrometry, and electrochemical technologies are commonly used in these facilities. However, process conditions for certain streams present major challenges for these traditional technologies. Techniques based on optical spectroscopy, including near-infrared (NIR), infrared (dispersive and Fourier transform), and Raman spectroscopy, can provide analysis solutions for these challenging stream conditions. Raman spectroscopy is particularly useful for streams containing homonuclear diatomic gases, such as H2 and N2. The simpleness of the gas Raman technology gas methods verses model based chemometrics analysis will be shown. The end user can change stream compositions easily, change measurement cycle times, and recalibrate the system as needed if the process changes.
