Abstract

Based on the earlier published mathematical model the problem has been solved of the optimum distance between the wall flow deflecting rings. These rings of small width placed near the wall of a packed column provide for the equality of the integral mean densities of irrigation in region near the column wall and in the bulk of the packing. An equation has been derived for the optimum distance between the wall flow deflecting rings convenient for practical calculations. A practical example has been used to show that the wall flow deflecting rings substantially improve the distribution of liquid in the column.
