Utilizing Equation of State Models
Understand the crucial role of compressibility and its relationship to fluid density in pipeline hydraulics through the application of equation of state models. Starting with the ideal gas law, this content delves into more complex scenarios where natural gas is contaminated by sour gases like carbon dioxide and hydrogen sulfide. The Wichert and Aziz correction method is introduced for adjusting critical pressure and temperature in gas compressibility calculations. Follow along as we illustrate these concepts with a detailed example, demonstrating how to calculate the density of a natural gas mixture using the Standing and Katz chart. This method ensures accurate modeling for real-world pipeline conditions, accounting for the presence of contaminants and the impact of varying pressures and temperatures.
