Hydrodynamics and Mass Transfer Behavior of a Novel Structured Packing with Diversion Windows

Abstract:

A novel structured packing with diversion windows is developed with the objective of achieving comparable pressure drop, high capacity and preferable mass transfer efficiency. The hydrodynamics and mass transfer performance of the packing have been investigated using a 384 mm diameter column. Carbon dioxide desorption process for mass transfer experiments at room temperatures and atmospheric pressures were conducted. Compared with the traditional Mellapak 350X, both the liquid holdup and mass transfer efficiency of the novel structured packing (350X with diversion windows) are increased by 15% or so; additionally, the pressure drop presented a slight growth trend, about 20% higher. It is concluded that the novel structured packing with adding diversion windows can change the flow pattern of the liquid film on the packing sheet and increase the effective mass transfer area, as well as the gas-liquid mass transfer efficiency.
