3. Propylene is reacted with oxygen to form acrylic acid by: C3H6 + 1.5 O2 → C3H4O2 + H2O Propylene is fed to the reactor with 50% excess oxygen where the oxygen flow rate is 260 kmol/hr. Acrylic acid exits the reactor at 90 kmol/hr.
(a) Determine the entering flow rate of propylene in kmol/hr. (1 XP)
(b) Determine the extent of reaction (with units), then write the expression for the molar flow rate of oxygen exiting the reactor in terms of the extent of reaction (assuming no side reaction) and solve for this flow rate. (1 XP)
(c) Find the fractional conversions of oxygen and propylene assuming no side reactions are present. (1 XP)
There is a side reaction to form acetic acid by: C3H6 + 2.5 O2 → C2H4O2 + CO2 + H2O and the selectivity of acrylic acid to acetic acid is 13.8.
(d) Determine the total amount of oxygen that reacts due to the two reactions. (1 XP)
(e) Determine the yield of acrylic acid. (1 XP)
(a) Determine the entering flow rate of propylene in kmol/hr. The ratio of propylene and oxygen as per the equation is 1... View the full answer
