Sistema de controle de temperatura para produção de biodiesel.

Abstract

Diesel is going extinct, with estimates for 2067, to avoid an energy crisis an ecologically sustainable substitute, the biodiesel, is needed. To optimize its production, it is necessary to carry out a temperature control, improving the yield and accelerating the production process. In this work, a PID temperature control system was developed, through a Labview-Arduíno integration, to act in a biodiesel reactor prototype. Three sets of PID parameters were found, one through the methods of Ziegler and Nichols and Cohen and Coon, another through empirical tests with and without the performance of a precontrol. The Ziegler and Nichols and Cohen and Coon parameters were obtained through the reaction curve, obtained by applying a step sign to the system and then following the method tables. At the end of the study, the performance of the parameters was compared. The experimental unit and the control system will be made available to the institution in order to enable experiments to students to visualize the performance of the control system and produce biodiesel on a small scale.
