G. Computer Simulation Problems

G1. Use a process simulator to completely solve Example 6-1. Do not assume CMO. Compare temperature and mole fractions on each stage to the values obtained in Example 6-1 after one trial.

G2. You have an ordinary distillation column separating ethane, propane, and n-butane. The feed rate is 100 kmol/h and is a saturated liquid at 10.0 atm. The mole fractions in the feed are ethane = 0.2, propane = 0.35, and n-butane = 0.45. The column has 28 equilibrium stages and the feed is input on stage 8 in the column (counting from the top down). The feed is input above the stage. The column pressure is 10.0 atm. and can be considered to be constant. The column has a total condenser and a kettle type reboiler. The external ...
