Process Modeling, Simulation and Design of Multi Pass Falling Film Desorber

Keyur S. Thaker and Vishal K. Varma

Abstract—Falling film column is a versatile piece of process equipment, which can be used as absorption, desorption, evaporation and distillation. In present work a utility two pass falling film column was used as gas-liquid desorber, operating in continuous mode of operation. Free HCl gas dissolved in 2-EHCF product was stripped/desorbed by using hot water utility. A diffusion based mathematical model was proposed to estimate effect of film thickness and column height on concentration of dissolved gas theoretically. Simulation with MATLAB shows a reasonably good agreement with experimental data. A systematic procedure is also presented for design of various critical process parameters. Work was further extended to study the absorption with chemical reaction for two different products.

Index Terms—Absorption, desorption, falling film, masstransfer.
