4 marks Question 2 Distillation columns are used to components, and make up over 95% industries. A commonly used distillation column is a propylene-propane splitter. The overhead product from this column is used as a feed stock for the production of polypropylene, which is the largest quantity of plastic produced worldwide. The figure below is a propylene-pro splitter (Cs refers to propane and C3 refers to propylene). The steam is used to provide energy and is not involved in the process material balance. Determine the overall and component balances of the system. separate light boiling components from heavier boiling of the separation systems for the chemical process opane 74,000 lbh R. 99.7 wt% CS 0.3 wt% C3 106,000 tbh 70 wt% C 30 wi90 C3 Steam 34.000 Ib/h 10wt % CS 90 wt% C3 Figure 1: Propylene-propane splitter. 7 marks
