Question

The cumene process is used to convert benzene and propene in the presence of oxygen to phenol and via the following reaction. C,H,0 This reaction is carried out in with excess benzene and excess o ensure that no side reactions occur. A 1.11 ratio of to propene is fed to a reactor in the presence of 29.5% excess air (N2 o2. 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 column separates products from the reactants, Any unreacted reactants are fed into the fresh feed stream. products are directed to a second distillation column that following acetone from the phenol. 130 kg/hrof phenol is produced fromthis process, answer the questions. First, label the process flow diagram below, putting either a given num or the or in each Do not leave any spaces blank. names are shown for reference later. mol/hr mol CeHelmol mol CsHemol Fresh Feed Reactor Feed mol/hr f. moUhr Reactor mol/hr Condenser mo/hr Distillation Column 1 mol gas/hr mol CsHwmal Previous
