A gas stream containing n-hexane in nitrogen with a relative saturation of 0.58 (as a fraction, multiply by 100% if you prefer %) is fed to a condenser at 75 deg C and 3.0 atm absolute. The product gas stream and condensed hexane stream emerge at 20 deg C and 3.0 atm absolute. Calculate the amount of heat flow in kJ required per gmol of hexane condensed. Your answer will be negative.
