In this article, a control strategy for a production process will be developed, consisting of a heated reactor acquired through a steam coil. Besides the controlled variable that is the concentration of the product, CB , the level and the temperature are additionally controlled. The PID controllers were tuned using the procedure of the first order model plus dead time (FOPDT). Finally, several simulations were carried out under different operating conditions. The first test carried out consisted of operating the system under nominal conditions, making CB(set)= 0.4. An overshoot of 0.55% for the concentration of B, which is considered quite low, in terms of the establishment time a considerable reduction was observed, it went from 30 min in an open loop to 15 min in a closed loop; additionally, a null steady state flaw is achieved with which the effectiveness of the control loop is verified.
