Modeling, Simulation and Analysis of Natural Gas Processing Routes Using HYSYS Design Applications

Abstract

This paper focuses on the modeling and simulation of natural gas processing routes using HYSYS design applications, aimed at understanding the performance of gas processing routes. The objective is to simulate and analyze the thermodynamic behavior of the system under different operation. HYSYS, a leading process simulation software, was employed to model various unit operations, including the slug catcher, de-ethanizer, lean gas purifier, and debutanizer, to evaluate the material and energy balances, pressure-temperature relationships, and phase transition points. The results revealed key trends, such as the relationships between pressure, temperature, volume, enthalpy, and entropy, which are crucial for understanding the process dynamics, The study identified the specific conditions under which phase changes occur, including the bubble points, and emphasized the importance of accurate modeling in predicting the performance of each unit operation. The simulation also highlighted potential areas for improvement, such as the reduction of impurities in lean gas, which can enhance product yield and profitability. Overall, this research demonstrates the effectiveness of HYSYS simulation in modeling natural gas processing. The findings serve as a foundation for further studies aimed at improving the economic and environmental sustainability of natural gas processing industries by optimizing key parameters of the system such as pressure, temperature, etc.
