Desenvolvimento de um sistema SCADA para planta de troca de calor.

Abstract

Data acquisition systems have been increasingly intensively applied at many industries, these systems provide a series of social, economic and safety benefits on the industrial environment. Analytics can be incorporated to the process allowing significantly improvements. This work presents the development of supervision system for a Shell-to-Tube heat exchange plant in which information is obtained from six sensors and through modification of the parameters of 4 actuators. In combining sensors and actuators it is possible to develop a series of control loops. In this system 7 control loops were implemented; therefore, it is possible to monitor and act on these control loops and in the plant operation without any active control loop. For the SCADA development it was selected the software Elipse E3 due to its credibility on the market, being used by many important companies such as Sadia, WEG and Mercedes-Benz. The software also is certified by the OPC Foundation. Communication protocol used at the plant, together with devices that operate with WirelessHART technology.
