Abstract
Absorption towers packed with split metal Raschig rings have a higher void content than towers packed with ceramic Raschig rings of the same nominal size. This increased void volume is due to the thinner wall of the metal ring. This higher void space should also result in lower pressure drops than would be encountered with ceramic rings. The purpose of this research program was to determine the pressure drop-flow characteristics of this packing, and to develop suitable correlations for design of packed absorption towers.
Split metal Raschig rings of one-half and one inch nominal sizes were tested to determine their pressure drop characteristics in a twelve inch packed tower designed by the author at water feed rates of 0 - 10,000 lb/hr ft2 and at air feed rates of 100 - 1500 lb/hr - ft2. Similar data were obtained for one inch ceramic Raschig rings.
It was found that lower pressure drops at equal flow rates were obtained with the metal Raschig rings. Empirical equations were developed for all data below the loading points as well as a method for predicting the loading points for varying liquid-gas rates.
