Title:Application of IR absorption measurement at high pressures for the analysis of the gas composition in a polymerization processAuthor(s):Johannes Kilian Sell, Bernhard JakobyAbstract:We investigate the possibility of online-monitoring of a gas phase polypropylene polymerization by application of infrared absorption measurement. It is demonstrated that, even though the absorption coefficients depend on pressure and gas composition when measuring at typical polymerization conditions, the composition of a gas mixture can be accurately determined by application of modern evaluation algorithms. Furthermore, a potential simplification of the measurement system (by building dedicated systems, which measure at specific wavelengths only) is identified.Booktitle:The 13th Mechatronics Forum International ConferenceEditor(s):Trauner Verlag & Buchservice GmbHPage Reference:page 779-783, 5 page(s)Publishing:9/2012Number:3
