The paper discusses a simple method of using the parametric continuation method to designate complex diagrams of steady states generated by systems and apparatuses used in chemical engineering. The main advantage of the discussed approach is the fact that it does not require the installation of huge professional IT systems. The deliberations are illustrated by examples of a tank reactor model described by the algebraic equations and of a tubular reactor model with longitudinal dispersion, described by the differential equations of the second order. Both models render solutions in the form of the so called multiple steady states. (C) 2010 Elsevier Ltd. All rights reserved.
