Abstract
AbstractNew data are presented for the system carbon dioxide—sodium hydroxide. The effect of CO3= build‐up upon KGa values was investigated first and the data were then used to construct a curve by means of which all data were corrected to an arbitrarily chosen reference state of 25% CO3= concentration. KGa values increased with increasing liquid rate but were not dependent on gas rate if the packings were operated below loading. For some packings examined in the loading range, however, KGa values increased with increasing gas rate.KGa values examined in relation to specific surface area were found to be very irregular in connection with rings. The surface‐area utilization pattern of the saddles was considerably more uniform. The ring and saddle data for the carbon dioxide‐sodium hydroxide system were in good qualitative agreement with the ammonia absorption data of Fellinger and the water‐water vapor data of Mehta and Parekh.
