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...

please help me solving this step by step... thank you :)
8.25 Sulfur dioxide is converted to sulfur trioxide by oxidation over a V20, catalyst at atmospheric pressure. In the reactor configuration shown in Figure P8.25, SO2 and O2 avalable at 300°C and 25°C, respectively, are preheated to 425°C and fed in stoichiometric ratio to the reactor. Conversion is 96% and, to keep the reactor temperature from rising too much, 10 kcal/g-mol of com bined feed is removed by external...
