A mixture of propane and n-hexane at 43.5 psi is to be separated.
a) Generate xy-plot for propane for this mixture at the given pressure. Use data in the DePriester charts.
b) If 40% of the 30 mol% feed is vaporized, what are the liquid and vapor mole fractions. Also, what is the drum temperature?
c) If the feed 60 mol% propane and the vapor stream is 80 mol% propane, what is the value of V/F?

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only
