Industrial Network for The Control and Supervision of The Acetic Acid Dispatch Process, and Its Influence on The Reduction of Chemical Contaminants for Operators

Abstract

This article develops the design and implementation of an industrial network for the control and supervision of the process of dispatching acetic acid, which aims to reduce the presence of this chemical in the environment, since the process is activated manually by the operators; what generates a lack of precision in several stages of the process, that brings in many occasions, spill of the acetic acid that is highly flammable and harmful for the health of the operators; For this reason, an industrial network controlled by a Siemens S71200 Programmable Logic Controller (PLC) was developed using the SIMATIC STEP 7 Software, and a Siemens S410 Distributed Control System (DCS), using the PCS7 V 8.1 Software; where the control logic was programmed and the distributed periphery was implemented. Once the industrial network is implemented, the result is a 19.44% decrease in the presence of acetic acid in the environment; this value is complying with what is established in the regulation of “Permissible Limit Values of Chemical Agents in the Work Environment”.
