Multicomponent Flash [ 40 points]\ A binary mixture with a relative volatility of 2 is to be separated in process that has two flash drums hooked\ together. The feed is an

100kmo(l)/(h)

of an equimolar mixture. In the first flash drum,

50%

of the feed\ entering the unit is vapourized. The liquid from this flash drum is heated and flashed in a second drum.\ The vapour product from flash drum 2 contains

50%

of the more volatile component. Based on this\ information and answer the following:\ (a) Draw a sketch of the process.\ (b) Write down the operating line equations of both the flash drums and show them on the y-x\ diagram.\ (c) Calculate the flow rates and compositions of all the product streams and list them in a\ stream table.
