Question 1 Consider the combustion reaction of butene. a. Write balanced stoichiometric equations for partial and complete combustion process. [2 marks]
b. Write the stoichiometric ratio of water (H2O) to oxygen (O2)? (Include the units).[4 marks]
c. Determine the theoretical amount of O2 (in lb-moles) to form 550 lb-moles of carbon dioxide (CO2). [4 marks]
d. If 100 mol/min of butene is fed into the reactor and 75% is completely combusted to CO2, determine the rate formation of H2O in both reactions. [5 marks]
Question 2 Performed the wet and dry analysis of stack gas if complete combustion of propane with the following gas stream. a. Oxygen with stoichiometric ratio [5 marks] b. Air with stoichiometric ratio [5 marks] c. 100 % excess air [5 marks]
Question 3 Repeat the procedure in Question 2 if the combustion of propane is partially complete. [15 marks]
Question 4 Acrylonitrile is produced in the reaction of propylene, ammonia and oxygen in the following reaction:C3H6 + NH3 + 3/2O2 C3H3N + 3H2O
The feed stream contains 10 mole% propylene, 12 % ammonia and the remaining is dry air. A fractional conversion of 30% of the limiting reactant is achieved.
a. Develop a complete process diagram of the above process.[6 marks] b. By assuming 100 mol of feed as basis, determine i. the limiting reactant,[5 marks] ii. the fractional excess of other reactants,[4 marks] iii. the amount of each components leaving the reactor.[10 marks]
