Popis: A rigorous method for solving the modified MESH equations for reactive distillation is elaborated. The equations were formulated as a problem-dependent homotopy in such a way that the homotopy path to a solution is continuous in the prescribed domain of distillation problems and rarely has turning points. This allowed us to develop a fast homotopy continuation solving method. The solution is found without any need for manual iteration, and no initial guess needs to be given by the user. The method has been tested extensively for highly non-ideal distillation. In this paper, similar success with reactive distillation will be reported and several examples of MTBE reactive distillation will be given. The robustness of the method makes it a valuable tool in the early design considerations of multicomponent ordinary and reactive distillation.
