Abstract: The initialization of process models for chemical engineering systems is often a challenge. While dedicated strategies exist for state of the art column models, novel models need to be initialized manually. In this contribution, we present a first application of these decomposition methods for supporting the initialization and solution of equilibrium- and non-equilibrium-type column models for distillation and compare them to well-known sequential solution methods for each. We show that these methods can supply viable solution procedures for nonlinear systems and are especially helpful in deriving new initialization techniques for novel process equipment.
