In our previous work, an approximate analytic solution for the composition distribution through a packed column for non-ideal multicomponent systems was derived by applying the perturbation method and the method of successive approximations to the fundamental equations for the column and was evaluated.
In this work, to improve the accuracy of the solution, concise general expressions for the known terms of the perturbation, i. e., terms consisting mainly of deviations of parameters calculated at the previous stage of successive approximations, have been derived. Moreover, to improve the accuracy of the solution to a design-type problem with the iterative use of these equations, a method of calculation is proposed to determine the optimum feed location so as to make the total packed heights for a given separation minimum.
It is found that the solution obtained by the proposed method coincides with that by an exact numerical method.
