n-Butane is converted to isobutane in a continuous isomerization reactor that operates isothermally at 149.0°C. The feed to the reactor contains 96.00 mole%n-butane, 2.00% isobutane, and 2.00% HCl at 149.0°C, and a 35.00% conversion of n-butane is achieved. In the following calculations, one should use at least five significant figures. Physical Property Tables Feed and Product Composition Taking a basis of 1 mol of feed gas, calculate the moles of each component of the feed...

A mixture containing 35 mole% n-butane and the balance isobutane at 10°C enters a heat exchanger at a rate of 24.5 kmol/h and at 1.96 bar pressure. The exchanger has been designed to heat and vaporize the liquid and heat the vapor mixture to 180°C. The heating fluid is a high molecular weight liquid with a constant heat capacity (Cp=2.62 kJ/kg C).It enters the exchanger at 215°C and flows countercurrently to the hydrocarbon mixture. According to the heat exchanger design...

Mole fraction of O2 = 571 Correct The mole fraction is the ratio of the number of moles of a given component in a mixture to the total number of moles in the mixture. The mole fractions can be represented in terms of pressures The total pressure PTOTAL = 0.180 atm +0.240 atm = 0.420 atm The mole fraction of CH4 in the mixture PCH 0.180 atm 0.420 atm = 0.429 PTOTAL Since it is the mixture of two gases,...
