100 moles/min of a mixture of 40 mol% n-pentane and 60 mol% n-heptane are fed through a valve into a flash tank. The flash tank operates at 600 mmHg. A T-xy diagram is provided on the next page. (a) Determine the bubble point and dew point of the feed mixture at 600 mmHg. (b) If the flash tank is operating at 60 0C determine; a. the compositions of the streams leaving the flash tank b. the flow rate in liters/min of the stream leaving the top of the flash tank.
