Abstract A flow dynamics and mass transfer CFD model was established based on non-intrusive surface reaction gas mass transfer experiments which were carried out to measure the distribution of mass transfer coefficient on the surface of structured packings. A new type of packing was developed using the CFD model and orthogonal experiments. The channel shape of the new packing is modified from the traditional triangle to a quadrangle to increase the hydraulic radius. The CFD simulation results show that the new packing with optimized geometry can reduce the pressure drop by 22.22%~23.03% while maintaining good mass transfer performance.
