48 Benzene is chlorinated to produce chlorobenzene (the desired product) and HCl : C6H6+Cl2C6H5Cl+HCl The Cl2 concentration in the feed is kept below 10mol% to prevent unwanted additional chlorination of the monochlorobenzene. Essentially all of the chlorine reacts under the reactor conditions. The byproduct HCl is converted back to Cl2 by oxidation: 4HCl+O22Cl2+2H2O The reaction is reversible; at the reactor conditions 60% of the reactants are converted to products. Physical property data for these compounds are given in App. B. You are given the following additional information: No O2 or H2O is allowed in the feed to the first reactor. Cl2 dissolved in water will preferentially partition into carbon tetrachloride, with a distribution coefficient (moles Cl2 per liter carbon tetrachloride/moles Cl2 per liter water) equal to 5.0. The solubility of Cl2 in water is 2.5gCl2/ liter water. The solubility of HCl in water is 380gHCl/ liter water. Sketch out a process flow sheet for production of chlorobenzene. Show the components in each stream on your flow sheet. Indicate the basis for separation in all cases (for example, difference in volatility or solubility) You do not have to do any calculations
