A Sequencing Method Applied to the Solution of a Linear Model of an Adsorption Column

Abstract

This paper discusses the application of a new transient simulation method, called the sequencing method, to solve a model representing a fixed bed adsorption column. In each time step, convection and mass transfer are applied successively on the column's mesh. Numerical simulations are given for linear adsorption isotherms. These results are compared with the traditional finite difference method. The results show that the sequencing method yields excellent fluid and solid concentration profiles along the column's length and a more accurate prediction of breakthrough time than the finite difference method.
