An important part of the development of process engineering is the calculation of the material balance, which is often very time consuming, especially when dealing with complex problems, because it involves analyzing a population of input variables and multiple simultaneous equations. This article presents a solution methodology through a computer program to facilitate calculations.

El presente trabajo está orientado a la creación de un programa que permita simular el comportamiento dinámico de un reactor de tanque con reacción continua cuyas siglas en inglés es CSTR (Continuous Stirred Tank Reactor), y se considera como una mezcla completa y, por lo tanto, se asume que sus propiedades son uniformes en todo el interior del reactor en el cual se desarrolla la reacción exotérmica de la saponificación de acetato de etilo con hidróxido de sodio. En la construcción del programa se emplea el software MATLAB Y Simulink. Para la simulación de la reacción de saponificación se introducen las concentraciones iníciales del acetato de etilo y el hidróxido de sodio, así como la temperatura constante del sistema de enchaquetado del reactor CSTR. Seguidamente, a consideración del usuario, se cambia los datos de las variables enunciadas para simular y observar, medi...

An important part of the development of process engineering is the calculation of the material balance, which is often very time consuming, especially when dealing with complex problems, because it involves analyzing a population of input variables and multiple simultaneous equations. This article presents a solution methodology through a computer program to facilitate calculations.

This paper is focused on creation a program to simulate the dynamic behavior of a reactor of tank with constant reaction which initials in English it is CSTR (Continuous Stirred Tank Reactor), and is considered as a complete mixture and, therefore, it is assumed that their properties are uniform throughout the reactor in which the exothermic reaction takes place of the ethyl acetate saponification with sodium hydroxide. In building the software program used MATLAB and Simulink. For the simulation of the saponification reaction are introduced initial concentrations of ethyl acetate and sodium hydroxide, and the constant temperature jacketing system of CSTR reactor. Next, consideration of the user, changes the data set of variables to simulate and observe, through graphs, the concentrations of ethyl acetate, sodium hydroxide, sodium acetate and ethyl alcohol function of time of the process...
