✦ Synopsis
Numerical solutions of the dimensionless equations describing multicolumn adsorption processes are presented. The columns are operated in series and move periodically countercurrent to a continuous fluid flow. Results are given for intraparticle mass transfer resistance separately and in combination with lilm resistance assuming a linear adsorption isotherm. Comparisons are made with columns in periodic operation and in continuous countercurrent operation. The utilization of the particles in a multicolumn arrangement, or equivalently in a pulsed bed system, compared to that in a column in continuous countercurrent operation is commonly about 80% for two columns in series and more than 90% for four columns in series, when the total column lengths and the fluid tlowrates are the same.
