In the natural gas industry the amount of water contained in gas streams is given in Ib of water per MMSCF of dry gas ( lb/MMSCF). Consider a gas mixture containing 50mol% methane, 30mol% ethane, 15mol% propane and 5mol%n-butane. What is the maximum amount of water in Ib/MMSCF that it can hold at pressure P=5 bar and temperature T=10C. Assume that the Peng-Robinson equation can be used for the calculation of thermodynamic properties of the gas stream and liquid water. Round your numerical result to a whole number. Note: The maximum amount of water at a given temperature and pressure, is the quantity of water in the gas that if exceeded a drop of pure liquid water will be formed at the prevailing temperature and pressure. Unit Conversions: 1 MMSCF= 1195.3kmol, 1kg=2.2046lb
