Extracted text: The cumene process is used to convert benzene and propene in the presence of oxygen to phenol and acetone via the reaction C6H6 + C3H6 + 02 → C6H5OH + C3H6O This reaction is carried out with excess benzene and excess oxygen to ensure that no side reactions occur. A 1.19 ratio of benzene to propene is fed to a reactor in the presence of 31.5% excess air (N, and 02). The first pass conversion of propene is 100%. The products leave the reactor and enter a condenser where the gaseous nitrogen and oxygen leave the process and the liquid organic products are fed to a distillation column. The distillation column separates the products from the reactants. Any unreacted reactants are fed into the fresh feed stream. The products are directed to a second distillation column that separates the acetone from the phenol. If 15.8 kg/hr of phenol is produced from this process, answer each of the questions. First, label the process flow diagram, putting either a given numeric value or the words "unknown" or "none" in each space. Do not leave any spaces blank.
