EFFECTIVE AND WETTED AREAS FOR ABSORPTION IN PACKED COLUMNS

simulation of packed columns for multicomponent adsorption

the dynamics of multicomponent adsorption in a fixed bed adsorber is examined numerically. the dynamic model of adsorption in the packed column included axial dispersion and variable space velocity along the bed for the multicomponent adsorption adsorption the pore fluid and the solid phase are in equilibrium with a nonlinear isotherm. the numerical solution is based upon the modified lax-wendr...

Photopolymerized sol-gel frits for packed columns in capillary electrochromatography.

Porous sol-gel frits are fabricated in a capillary column by filling it with a solution of 3-(trimethoxysilyl)propyl methacrylate, hydrochloric acid, water, toluene (porogen), and a photoinitiator (Irgacure 1800) and exposing it to UV light at 365 nm for 5 min. The separation column (30 cm x 75 microm I.D.) contains between the inlet and outlet frits a 15-cm packed segment filled with 5-microm ...

A Numerical Case Study of Packed Columns

This paper presents results concerning the validation of a recently developed packing algorithm. The basic ethos of this algorithm, known as DigiPac, is to use threedimensional methods to digitise particle shapes, and to use this digital information directly in computations of how particles pack together without further conversion or the need for modelling. A variety of simulations of packed co...
