Modelling and Simulation of The Processes of A Working Fuel Gas Conditioning Unit for A Gas Turbine
Abstract
This research examines the design and simulation of a fuel gas conditioning unit (FGCU) for gas turbines using Aspen HYSYS. Gas turbines demand high-quality, contaminant-free fuel gas for optimal performance and longevity. The study focuses on developing a comprehensive model to remove impurities, regulate pressure, and control the dew point of natural gas to meet turbine specifications. The methodology involves modelling FGCU components, including separators, chillers, and dew point control units, to process a mixed feed containing hydrocarbons and contaminants. Simulations in Aspen HYSYS captured the behavior of these units under various operating conditions. Critical performance metrics such as gas purity, temperature, and pressure were optimized during the simulation. Results indicate that the FGCU effectively removes liquid hydrocarbons and moisture, achieving a 99.5% purity level in the processed gas. The final gas stream was delivered at a temperature of 15.57°F and a pressure of 800 psia, meeting stringent gas turbine requirements. The simulation also highlighted areas for energy optimization and operational efficiency. The study concludes that FGCUs significantly enhance gas turbine efficiency by ensuring fuel gas quality. Challenges such as energy consumption during conditioning and potential system inefficiencies were addressed, providing actionable insights for improvement. It is recommended to integrate advanced monitoring systems and optimize heat exchange processes to enhance system efficiency further. This research offers a robust framework for implementing FGCUs in industrial applications, contributing to cleaner and more reliable power generation
