Abstract

The purpose of this study was to measure the temperature profile, to determine the mean temperature and to investigate the interaction between fluid temperatures and hydrodynamic behaviour of a 0.1 m diameter 1 m height absorption column packed with 0.012 m Raschig-rings. The values of measured parameters were chosen in the good operating domain of the packed tower and below that using the practical loads and temperatures of SO2 absorption from low concentration gases by sodium-citrate buffer solution. To determine the temperature, profile electric semiconductor sensors were placed into the packing along the vertical axis of the column. The data recording and processing were aided by a personal computer. The measured data supported our consideration, that in the lower 10 cm of the column height the gas phase becomes saturated with the vapour of the liquid phase which causes a fast cooling of both fluids, while above that the column works as counter-current heat exchanger.
