# Sulfur dioxide is oxidized to sulfur trioxide Essay

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)
