Abstract

The non-stoichiometric thermodynamic equilibrium simulation program for the biomass gasification process was developed using the Python programming language. It is featured with a GUI (Graphical Users Interface), to facilitate user interaction. The program is designed to calculate the composition of gas producer with 6 components involved, they are CH4, CO, CO2, H2, N2, and H2O. The design of computational algorithms for calculating non-stoichiometric thermochemical equilibrium models is converted into Python code. The GUI consists of input and output facilities in form of tables and graphs of calculation results. The input facility is designed in such a way that the user can vary the gasification temperature and the equivalent ratio. The calculation results of the simulation program are verified with the calculated data manually to ensure that there are no errors in the algorithm or writing program code. It is also compared with the experimental data from previous studies to see the accuracy of the thermodynamic model in predicting the composition of gas producer. The non-stoichiometric thermodynamic equilibrium simulation program for the biomass gasification process can predict the composition of producer gas with a fairly good level of accuracy and can be used as a learning medium in studying thermodynamic equilibrium.

Abstract

Research was conducted to develop a data acquisition and control system using Arduino on a Windows operating system based on a Graphical User Interface (GUI). The data acquisition system can store measurement results data which can be used for analysis of the control system. The devices used are an Arduino type Mega 2560 microcontroller and a K type thermocouple using the MAX6675 driver. The GUI was created in the C# programming language using the WinForms application. Data acquisition is carried out using an Arduino device connected to a computer via a USB connection. The control system works by regulating the water heater connected to the relay by Arduino using the setpoint value on the GUI. The data acquisition and control system is designed using PID control mode with parameters Kp = 1.189159, Ki = 2.038558, and Kd = 0.173419. Based on the experimental results, the PID control mode has the smallest error value, namely 871.7 using the IAE method and 402,457 using the ITAE method.
