Acrylic acid (CH₂=CHCOOH) is used to prepare poly-mers, adhesives, and paints. The first step to make acrylic acid in-volves the vapor-phase oxidation of propylene (CH₂=CHCH₃)to acrolein (CH₂=CHCHO). This step is carried out at 330Cand 2.5 atm in a large bundle of tubes around which circulates aheat-transfer agent. The reactants spend an average of 1.8 s inthe tubes, which have a void space of 100 ft³. How many poundsof propylene must be added per hour in a mixture whose molefractions are 0.07 propylene, 0.35 steam, and 0.58 air?
