A mixture of furan(1) CCI4(2) with initial overall molar composition of zi2-0.5 and total flow rate F-200 mol/h is fed into a flash drum (drum 1) that operates at T-30 C (a) What is the bubble point of this mixture? What would the bubble point be if the mixture behaved ideally? (b) Using the Pxy diagram for this binary mixture (Fig. 2A) find the pressure and vapour molar compositions inside drum 1 when the mole fraction of furan in the vapour is yi-0.65 (c) What are the flow rates of the vapour (V) and liquid (L) streams leaving flash drum 1? (d) [See Fig. 2B] In order to further improve the separation of this binary mixture, the vapour stream leaving drum 1 is fed into a second flash drum (drum 2), which also operates at T 30°C. (i What would the pressure and compositions of streams L' and V' be if we desired to operate drum 2 at a pressure that causes 50% of the feed to vaporise (Le, (ii) What is the overall fractional recovery of furan in stream V' (ie., [furan in V'/[furan in F)? Note: To save time, perform as many of the above calculations as possible using a graphical method. Although graphical calculations must be performed with relative precision, there is no need to strain your eyes. Please make sure that you demonstrate clearly how you use the graph for solving the problems
