A flash vessel is used to separate a mixture that consists of ethane, propane, n - butane, n - pentane and n - hexane. Component
A flash vessel is used to separate a mixture that consists of ethane, propane,
butane, pentane and hexane. Component flowrates and Antoine
coefficients are shown in Table Q Antoine equation may be used to estimate
the vapour pressure of component and is given in Equation
where is given in and temperature in Kelvin. Determine the
following:
a Find the components molar flowrates and fractions in its overhead and
bottom streams if the vessel is operated at and atm note: atm
Use butane as key component.

b If recovery of pentane is to be reduced to with vessel operated at
atm, determine the operating temperature that can achieve this
separation task.
