✦ Synopsis

The relaxation procedure is used for solution of two interlinked distillation columns. Both approaches-sequential iterative method and the block relaxation technique are compared. A new algorithm making use of simultaneous solution of all equations is proposed.

## Abstract A mathematical model and iterative correction algorithm are described for the exact solution of separation systems which contain interlinked columns in which some stages have two liquid phases and others have a vapor and liquid phase. The correction algorithm is based on Newton's method

The relaxation method used for solution of problems arising in design of multicomponent separation processes is discussed and new modifications are proposed. The use of certain techniques for convergence acceleration is studied. The number of iterations is then substantially reduced and effectivenes
