Modeling of Equilibrium Water Condensation in Natural Gas Flowing Through Joule Thompson Valve

Natural gas is a hydrocarbon gas mixture that consists mainly of methane and other higher alkanes. However, it may contain some impurities such as carbon dioxide, water, nitrogen, and hydrogen sulphide. The presence of these impurities might cause problems in the pipeline, fittings, valves and the c...
