Modeling and simulation of vacuum evaporation process through graphical interfaces

Abstract

This article presents the development of a software with graphical interfaces for the simulation of the evaporation process in simple and multiple effects, as part of the construction of a virtual laboratory of unitary operations in distillation and evaporation. The design and construction of the user interfaces was carried out in the QtCreator application, later the coding of the calculation algorithms was developed in the Python programming language, due to the appropriate characteristics that it presents, in Regarding the construction of graphs and methods of solving equations. The calculations carried out in the software allow the determination of temperatures and pressures, the output flows and the corresponding enthalpies; presents in graphic form the dynamic behavior of the variables incorporated in the process model. With the developed system, it is possible to perform simulations of the evaporation process in a nonstationary state for simple and multiple effects, considering solutions of sodium hydroxide, sucrose, milk, sodium chloride and sulfuric acid.
