CFD Simulation of Pressure Drop, Mass Transfer Efficiency and Temperature Distribution in a Structured Packing

摘要

This paper describes the results of computational fluid dynamic modeling of hydrodynamics, heat and mass transfer simultaneously in Flexipac 1Y operated under counter-current gas-liquid flow condition. The simulation was performed for binary mixture of Methanol-Isopropanol distillation. The pressure drop, the Height of Equivalent to Theoretical Plate (HETP) and temperature distribution across the column were calculated and compared with experimental data. The mean absolute relative error (MARE) between CFD predictions and experimental data for the pressure drop, HETP and temperature profile are 20.7%, 12.9% and 2.8%, respectively.
