Resumen:
This paper presents a rigorous mixed-integer nonlinear programming (MINLP) model for optimal synthesis and
design of dual-purpose seawater desalination plants. The proposed superstructure considers more alternative configurations
than the model recently proposed by Mussati et al. [1] and all process equipment is modelled in a rigorous
way. The MINLP model introduces binary variables in order to select equipment for the cogeneration plant. The
detailed model for the MSF desalter developed by Mussati et al. [2] was considered. The MSF mathematical model
involves the real-physical constraints for the evaporation process. Nonlinear equations are used to model all plant
equipment rigorously in terms of chemico-physical properties (enthalpies, entropies, vapor pressure) and design
equations (efficiencies, NEA, BPE, heat transfer coefficients, momentum balances, among others). The proposed model
is not only useful for synthesis, but also for analyzing different design alternatives. The model has been implemented
in a general algebraic modelling system [4]. Several study cases were successfully
