Consider a stream of the following chemical species: Hydrogen - 7 mol %, Methane - 85 mol %, Propane - 5mol%, i-Butane - 2.2 mol %, n-Hexane-0.8 mol %. K = SRK, H = SRK. a. What is the dew point temperature at 25 bar? b. What is the gas phase viscosity at saturation and 25 bar? What do you find when you try to determine the bubble point pressure at 40 °C? d. Can you explain why part (c) does not work by using the "Phase Envelope Plot" function in CHEMCAD? e. Can you determine the critical temperature and pressure using the plot in part (d)?
