Question:

In Figure, 150 kmol/h of a saturated liquid, L1, at 758kPa, of molar composition, propane lo%, n-butane 40%, and n-pentane 50%, enters the reboiler from stage 1. What are the compositions and amounts of VB and B? What is QR, the reboiler duty? Use a simulation computer program to find theanswers.
