Sulfur dioxide is oxidized to sulfur trioxide in a small pilot-plant reactor. SO2 and 100% excess air are fed to the reactor at 450°C. The reaction proceeds to a 65% SO2 conversion, and the products emerge from the reactor at 550°C. The production rate of SO3 is 1.00 x 102 kg/min. The reactor is surrounded by a water jacket into which water at 25°C is fed.
(c) Calculate the minimum flow rate of the cooling water if its temperature rise is to be kept below 15°C.
(d) Briefly state what would have been different in your calculations and results if you had taken elemental species as references in part (b)
