Cumene production generally involves irreversible and exothermic reactions that leads to an increase in product temperature and needs to be cooled for further processes. The high temperature of reactor product can be utilized as a heat transfer fluid in heat exchanger. This modification process is essential for improving energy efficiency by recycling the reactor output with high temperature as a heat transfer fluid, so that the implementation of replacing the heater with a heat exchanger can be carried out for the process of increasing the initial feed temperature. In an effort to enhance energy efficiency in the cumene production process, simulations were conducted using HYSYS and the comparison of energy efficiency for both basic and modified processes can be evidenced by comparing the total amount of energy required during the process. The results shows that the total amount of energy required for the modified process is 39,814,003.7 kJ/h, while for the basic process is 40,588,937.4 kJ/h, with a difference of 774,933.7299 kJ/h. Since the total amount of energy required in the modified process is smaller than the basic process, then the modification process will increase the energy efficiency of cumene production.

Thermoregulators are devices or applications which control temperatures. Examples of such devices are air conditioners for the everyday use of people, or heat exchangers for use in industrial purposes like chemical power plants. These kinds of devices most of the time, if not all, require a feedback system for precise and accurate observation and monitoring of data and in turn maintain or manipulate the temperature to a more favorable value to lessen or mitigate damages and prevent such possible disasters. The paper aims to simulate a feedback-controlled heat exchanger system to lessen the errors done upon the physical execution. A program called MATLAB is required to show computations and calculations of possible outcomes with the user's inputs as a simulation with ideally precise outcomes. A program for calculation runs through MATLAB while the simulation is shown for monitoring and observing on SIMULINK.

The paper presents an automated system for the temperature control using a PIC microcontroller, a digital temperature sensor with I2C and a MOSFET as actuator. The control strategy is a proportional-integrative one, preceded by an on-off algorithm. The most important data is presented on a graphical interface. In order to send the parameters of the process and the command states to the computer, the serial communication is used.
