Benzene as a saturated liquid at 5,000 mmHg is fed to avaporizer. The product from the vaporizer is a superheat vapor at165°C and 4,550 mmHg.
For a flow rate of 2,500 moles/min of benzene, how much isneeded (kW)?
If steam is available at 500°C and 20 bar and condenses to asaturated liquid at 20 bars, how much steam (kg/hr) is needed tovaporize the benzene?
Know: ΔHv = 30.765 kJ/mol, Tb = 80.10°C, SG = 0.879, Cp (l) =126.5 * 10^-3 + 23.4 * 10^-5 T (°C), Cp (v) = 74.06 * 10^-3 + 32.95* 10^-5T - 25.20 * 10^-8 T^2 + 77.57*10^-12 T^3
