Experimental and numerical studies were conducted on the mass transfer efficiency of new wire gauze structured packing. For serving this purpose, various operational conditions were studied to assess the optimal parameters such as HETP of PACK-2100 in the distillation column. The results indicate that the HETP values are enhanced in comparison to conventional ones. In addition, the HETP slowly increases from 4 to 6 cm as mass flow rates of air and liquid flow are increased. The numerical simulations were also performed to describe the performance of the PACK-2100. The Eulerian-Eulerian multiphase approach is applied to calculate the value of HETP and pressure drop. The computational results confirmed that our experimental results. The average relative error between CFD predictions and the experimental data for the prediction of mass transfer efficiency is 20.45%. [ABSTRACT FROM AUTHOR]

Extensive usage of the structured packings in various industrial applications has led to comprehensive investigations of their properties and performance. Among various methods of modeling, computational fluid dynamics (CFD) is an efficient approach to present full details of fluid behavior inside structured packings. This review focuses on the application of CFD for investigation and development of the structured packings. Applications of the CFD for the simulation of gas–liquid flow behavior, flow distribution, liquid hold-up, and mass transfer are extensively reviewed. Literature survey of the available CFD studies can provide a comprehensive and descriptive insight about governing mechanisms of fluid flow inside packings and reveals qualitative/quantitative effects of the process variables on the packed system.
