The phenomena of physical absorption of a concentrated gas component in a wetted-wall column operated in laminar regime were simulated by solving the Navier-Stokes and diffusion equations with a finite difference technique. For simultaneous analyses of gas and liquid phases, which have quite different Schmidt numbers, a finer-mesh width was used in the gas phase adjacent to the gas-liquid interface. In this way, the computation time was significantly reduced.
Experimental study of the absorption of acetone vapor into pure water was carried out to check the theoretical analysis.
It was found that the method of analysis used in this study can express the experimental results accurately and allows us to study various factors affecting the absorption rate, such as feed gas concentration, variation of flow rate of gas and liquid phases and gravitational acceleration.
