Chlorine dioxide gas is used in the paper industry to bleach pulp produced in a Kraft mill. The gas is produced by reacting sodium chlorate, sulfuric acid and methanol in lead-lined reactors: 6NaClO3 + 6H2SO4 + CH3OH → 6ClO2 + 6NaHSO4 + CO2 + 5H2O Suppose 14 moles of an equimolar mixture of NaClO3 and H2SO4 are used per mole of CH3OH as shown in the figure: a. Determine the limiting reagent. b. Calculate the reagent flows required to produce 10 metric tons per hour of ClO2, assuming a 90% conversion is obtained.
