   Abstract

   For investigations of concentration profiles around bubbles in millichannels as Taylor flow and in bubble columns two in situ real-time process analysis systems were developed. The first system uses laser Raman spectroscopy combined with real-time digital holography. The Raman part of the system is based on a custom pulsed high-energy laser. With this process analysis system, it is possible to measure concentrations of many chemical compounds selectively, with a spatial resolution in the micrometer range during a 10 µs laser pulse. Due to the two combined principles, the determination of the position of a measured local concentration relative to the gas bubble is possible and has been demonstrated. The second real-time process analysis system is especially suited for colored chemical reactions. The system is based on real-time UV/VIS 2D tomography such that with time the third dimension of a 3D concentration profile in the bubble wake can be determined. It consists of fast line sensors illuminated by a laser light sheet. This light sheet originates from a laser spot moving around one third of the bubble column repeatedly. This system is applicable to freely ascending single bubbles as well as bubbly flows in bubble columns.
