Introduction
Dew point calculations are of great importance in various engineering applications, particularly in chemical engineering, environmental science, and HVAC systems. These calculations determine the temperature at which a gas mixture begins to condense into a liquid, and this information is crucial for assessing humidity levels and designing efficient systems. MATLAB, with its robust computational capabilities, provides an excellent platform for performing these calculations.
To determine the dew point, two different algorithms can be utilized: the Antoine equation method and the statistical regression method. The Antoine equation method uses empirical correlations for vapor pressure and easily performs dew point calculations based on the known properties of the components.
The bubble and dew point temperature of a mixture is one of its thermodynamic properties, which is a function of pressure and percentage composition of the mixture components. This property is the basis of separation in distillation operations. Due to the non-linear nature of Antoine’s equation, the bubble and dew points must be obtained through trial and error.
Process Description
The process of dew point calculations in MATLAB begins with the collection of necessary data, including temperature, pressure, and gas composition. Next, using various algorithms like the Antoine equation method or statistical regression, calculations related to vapor pressure and the thermophysical properties of the mixtures are performed. In the Antoine method, the vapor pressure of each component is extracted using defined empirical relationships, and then the dew point temperature is calculated.
In the statistical regression method, experimental data is used to fit an appropriate model, making the relationship between different parameters clear. This process not only aids in a better understanding of temperature and humidity levels but also contributes to improving the performance of industrial systems and reducing energy consumption.
In this project, dew point calculations are written with MATLAB coding for multi-component mixtures. A full explanation of the algorithm will also be sent after purchase.

Conclusion
In conclusion, dew point calculations using MATLAB and various algorithms such as the Antoine equation and statistical regression serve as powerful tools for analyzing the behavior of gas mixtures and managing humidity in engineering systems. Each of these methods has its unique characteristics and advantages; the Antoine method offers speed and simplicity in calculations, while the statistical regression method provides greater accuracy in more complex conditions.
The choice of the most suitable algorithm depends on the specific needs of the project, the type of data, and the environmental conditions. These analyses not only assist engineers in designing more efficient systems but also lead to optimized energy consumption and cost reductions. Furthermore, a better understanding of dew points contributes to more accurate predictions regarding climate and operating conditions, significantly enhancing the sustainability and performance of systems.
