IGLESIAS, Omar A; SOTO, Juan D  y  PANIAGUA, Carmen N. Significant Variables of Optimum Design in Process Simulators. Inf. tecnol. [online]. 2012, vol.23, n.1, pp. 13-18. ISSN 0718-0764.  doi: 10.4067/S0718-07642012000100003.

Some modules have been developed for an open code process simulator, Sim42, accessible through the Web. The objective is the consideration of the design variables in the optimum structuring of industrial processes, in the teaching of Chemical Engineering. The simulator must be able to: a) estimating the investment in equipments, the costs of services and inputs and the revenues for sale and b) managing an optimization method for non lineal restricted problems. Since both facilities do not exist in Sim42 new modules were added to the available code, as well as others ones that complete the analysis. The developments are applied to the simulation, analysis and optimization of a Linde cycle to liquefy a methane stream. It is conclude that having an open-source simulator that allows adapting its performance to the requirements of the concepts to be conveyed is highly convenient.
