Determining the saturation water content of a gas (the dew point) is a standard
but complex problem in thermodynamics, and excellent discussions of phase
equilibria calculations are given in many thermodynamics texts (e.g., Smith
mercial grades of propane require lower water contents (see Chapter 1).
concentration should be 0.1 ppmv or less. Chapter 7 discusses hydroprocesses
slightly. Chapter 10 discusses dehydration of liquids.

present a commonly used engineering correlation on the basis of experimental
measurements
