SYNTHESIS OF REACTIVE MASS-EXCHANGE NETWORKS WITH GENERAL NONLINEAR EQUILIBRIUM FUNCTIONS Academic Article uri icon

abstract

  • AbstractThe problem of synthesizing reactive massexchange networks (REAMENs) is addressed for which the equilibrium relations governing the transfer of a certain species from rich streams to reactive massseparating agents are nonlinear (convex and/or nonconvex). Previously developed synthesis procedures for REAMENs are not applicable to such cases, since they were developed for cases of linear and/or convex equilibria. Two peculiar phenomena are associated with REAMENs with general nonlinear equilibria: the location of a massexchangers may straddle the pinch point even for networks featuring the minimum cost of massseparating agents. To account for such intriguing characteristics, a systematic procedure is developed to synthesize costeffective REAMENs with general nonlinear equilibria. In addition, a robust solution procedure is devised to guarantee the identification of the global solution of the developed optimization programs. Applicability and usefulness of the proposed synthesis procedure are demonstrated via a case study on the desulfurization of gaseous wastes from a coaltomethanol plant.
