Controle do consumo de energia em uma plataforma de detecção de incrustações.

Abstract

One of the problems faced on the oil, food, chemistry and pharmaceutical industries is the appearance of fouling into the equipaments, wich gradually reduces the overall efficiency of the process and degrade the lifecycle of the equipments. The existence of fouling can significantly affect the efficient use of energy supplied to the system, which in this case comes from an electric machine. Focusing on energy efficiency, this work proposes an improvement for fluidic transport systems. The objective of this study is to find the best operating point regarding the use of the energy supplied to a fluid transportation system, and also establish the relationship between the power supply and the presence of fouling in the ducts. For this purpose, an interface was developed using LabVIEW software in order to group the information provided by the sensors, monitor the physical quantities associated with the process in question and send commands to the actuators to modify these quantities. With the data’s acquisition it was possible to identify the dynamic open loop system and thereafter applying controller tuning techniques in order to choose one to produce satisfactory responses to the closed loop behavior of the platform. It was also possible to find a relationship between the increase in the power supplied to the system as the increased of fouling inside the pipes.
