Diseño de un sistema de control automático para el evaporador doble efecto del laboratorio de ingeniería química de la Universidad de Pamplona.

Abstract

The chemical engineering program of the University of Pamplona has a double effect evaporation pilot plant where the unit operations practices are carried out, which lacks an advanced control system since it only has a basic level control in the evaporators. In order to strengthen the knowledge in the area of process control, it was proposed to study the critical process variables that directly impact the process, in order to design control strategies. In this project, the development of an optimal control system was proposed to improve the yield of the obtained product, the safety of the process and increase the energy efficiency, this was achieved by identifying the critical variables through the development of a mathematical model, with which He described the evaporation process from the balance of matter and energy, once this stage of the project was completed, the verification and calculation of the control strategies that allowed finding the stability of the system was ensured, guaranteeing a better response of the process through the Matlab software. . Subsequently, four control strategies were proposed, taking into account predefined selection criteria, in order to select the best control alternative that would adapt to the conditions of the process.
