Abstract
The Super Mini Ring (SMR), a novel random packing, has found wide application in liquefied petroleum gas purification and carbon dioxide absorption as it has particularly good performance at high liquid loads. In this study, the hydrodynamic and mass transfer models for this type of packing were studied and compared over a wide range of liquid loads (LW = 0-220 m3·m-2·h-1). The modified Billet and Schultes pressure equation was found to be superior to other models presented in the literature. Models used to calculate the flooding gas velocity and the height of the mass transfer unit for the SMR have also been presented.
