文章摘要

A regenerative absorption process for removal of SOx from FCC off-gas using LAS/H2SO4 solution as absorbant was studied and pilot-plant experiments were carried out. A mass transferreaction model for the SO2 absorption process was established based on pilot-plant experiments, and the concentration distribution of components in the liquid film, and the partial pressure and mass transfer rate of SO2 along the height of the absorption tower, was calculated from this model. The numerical simulation results were compared with the experimental results and proved that the model can be used for describing the SO2 absorption process.
