570 SCFH (standard cubic feet per hour) of a mixture of 70% propylene (C3H6) and 30% cyclopropane (also C3H6 ) is fed to a compressor where cyclopropane is separated by condensation. Two streams leave the compressor, a pure gaseous propylene stream, and a liquid cyclopropane stream. The system operates at 150Â°F. The outlet gas stream is at 600 psia and the inlet stream at 263 psia.

a)What is the ideal volumetric flowrate of the inlet stream in ft3/h?

b) Is ideal gas law a good approximation for the inlet stream? If not, which equation of state would you use to calculate the molar flowrate of the inlet stream?

c)You are trying identify the critical temperature and pressure of cyclopropane, but can only find the critical pressure in an old handbook (Pc=803.5 psia). Given that the molar flowrate of the feed gas mixture is 1.92 lb.moles/h, estimate the critical temperature of cyclopropane in Â°R.

d)How could you estimate the density of (i) the propylene outlet stream, and (ii) the liquid cyclopropane stream, after they are brought to standard temperature and pressure? (write down equations you would use, do not calculate values)

A 831.0 g/hr stream of liquid methyl alcohol, also called methanol, (CH3OH) at 5.80 atm and 18.0Â°C was held at constant pressure, vaporized and brought to 236.0Â°C. Assume that methyl alcohol vapor behaves ideally for the temperature range and pressure given. FIND: The rate heat must be supplied to this system, Because this is an open system and there is no change in kinetic energy, potential energy, or shaft work, the rate of heat supplied to the system is equal to the rate of change in enthalpy of the process.

The change in enthalpy is a state property, meaning that it is path independent. Since table values for the specific enthalpy of methyl alcohol at the starting and final conditions are not available, you will have to calculate the change in enthalpy as the sum of a series of steps. Because the methyl alcohol is going from a liquid to a vapor, you know that you will need to utilize the heat of vaporization at some temperature, and the heat capacity equations of the liquid, the vapor, or both. You will also need the molar mass of methyl alcohol and its specific gravity. Choose the path that will allow you to calculate the total enthalpy change given these physical constants. Calculate the sum of each step\'s specific enthalpy, and multiply this value by the molar flow rate of methyl alcohol into the process.

STRATEGY: 1. Look up the relevant physical constants of methanol. 2. Determine the proper path to take. 3. Find ?H1. 4. Find ?H2. 5. Find ?H3. 6. Find ?Htot. 7. Find ?H. 8. Find Q.
