A mixture comprised propane (I) and n-hexane (2) are separated in

A mixture comprised propane (I) and n-hexane (2) are separated in flash drum. The system produce phases at equilibrium compositions of x1=0.30 and y1=0.75 of propane leaving the separator. (a) Determine the separator's temperature and pressure. (b) Using the temperature in (a), what is the pressure if y1=0.8. (c) Determine the vapour and liquid compositions leaving the separator in (b). (d) Using the temperature in (a), what is the pressure if x1=0.2. [3 marks] [8 marks] (e) Determine the vapour and liquid compositions leaving the separator in (d). [ 3 marks] [8 marks] [3 marks]
