Parameters Identification of a Mathematical Model for Liquid Distribution in Packed-Bed Columns.

Original language description

A complex identification method for determination of parameters of a mathematical model describing the liquid distribution in packed columns with biparametric boundary condition at the column wall is proposed. One of the parameters is directly determinedfrom experimental data for two cases of innitial irrigation: uniformly distributed initial flow and wall-introduced one. The other parameter is derived by consequent nonlinear optimization for itself and for the liquid spreading minimizing the residualvariance. The method is tested with three types of packing - Pall rings 25 mm, Intalox saddles 25x50 mm and Minirings 17x50 mm. The experiments are carried out in a packed column 188.6 mm in diameter, with both uniformly distributed and wall initial liquid flow, according to the method's requirements. For Pall rings and Intalox saddles, the parameters of boundary conditions, as well as the coefficient of liquid spreading are obtained. The existence of conditions under which the method in
