Abstract

An implementation of the Infinite DimEnsionAl State-space (IDEAS) based Shrink–Wrap algorithm for attainable region (AR) construction is developed, which identifies the multi-feed AR in reduced dimension (ARrd). The proof of the validity of the method is based on the stoichiometric characteristics of the reaction system and the properties of well-connected reactor networks, which allow the establishment of necessary and sufficient conditions for a point in mass fraction space to be in the multi-feed AR. The two-feed AR for methane steam reforming at isothermal and isobaric conditions is identified in the three-dimensional mass fraction space, and it is shown that for feeds consisting of pure methane and pure water, the equilibrium curves define the boundaries of the projections of the two-feed AR.
