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.

a. A mixture of 60 mol % n-proplycyclohexane and 40 mol % n-propylbenzene is distilled through a simple distillation apparatus; assume that no fractionation occurs during the distillation. The boiling temperature is found to be 157 °C (760 torr) as the first small amount of distillate is collected. The standard vapor pressures of n-propylcyclohexane and n-propylbenzene are known to be 769 torr and 725 torr, respectively, at 157.3 °C. Calculate the percentage of each of the two components in the...

A distillation column receives a feed that is 40 mole % n-pentane and 60 mole % n-hexane. The feed is saturated liquid at 2,500 lbmol/hr. The column is at 1 atm. A distillate that is 97 mole % n-pentane is desired. A total condenser is used. The reflux is a saturated liquid. The external reflux ratio is L0/D = 3. The bottoms from the partial reboiler is 2 mole % n-pentane. Determine the intersection (xq, yq) of the q-line with...

Calculate the vapor pressure at 80 C of a mixture of 35 mol % hexane and 65 mol % heptane.

Calculate the vapor pressure at 80 C of a mixture of 35 mol % hexane and 65 mol % heptane. Calculate the mol fraction of each compound in the vapor in equilibrium with the mixture in (1). If a simple distillation were to be performed on this mixture( from question 1 ), what would be the composition of the initial distillate? Suppose the mixture was to be distilled using a very efficient fractional distillation column. what would the composition of...
