Abstract

Cold pilot model experiments have been conducted in a 500mm-diameter plexiglass column packed with 1m four different HX and X700 type structured packings respectively. Data that characterize the hydrodynamic and mass transfer performance of two types of packings were obtained. The experimental results showed that the pressure drop, flooding gas velocity and theoretical stages per meter packing for different kinds of packing followed the same trend as for other structured packings. The HX700 type packing showed lower pressure drop and higher mass transfer efficiency than the X700 packing. Compared with the X700 type packing, the dry tower pressure drop and wet tower pressure drop with the HX700 type packing were reduced by an average of 25% and 40% respectively, while the flooding gas velocity and theoretical stages per meter packing increased by 12% and 30% respectively.
