Question 1 A flash tank is used to separate a liquid mixture of n-pentane and n-hexane. The liquid mixture contains 40 mol% n-pentane and is fed to the flash tank at 95C and at a rate of 100 mol/s. The pressure in the flash tank is 1 atm. For these calculations, use the following heat capacities: n-pentane: Coliquid) = 0.195 kJ/mol C) Cp (vapour) = [0.115 + 3.41E-4 T(C)] kJ/(mol C) If the temperature in the flash tank is 55C, can the tank be operated adiabatically? If not, how much heat must be added or removed? As part of your solution, complete the enthalpy table below.
