Characteristics of mass transfer and pressure drop of a new structured packing
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.
