Using the information given below draw and label a flowchart of the processes involved in production of phthalic anhydride. Use boxes and/or other symbols to represent process units and lines with arrows to represent inputs and outputs. Indicate the process conditions. Phthalic anhydride (PA) is produced via partial oxidation of o-xylene using oxygen. The feed to the plant is o-xylene and air. Air is compressed to approximately 2 bar in a centrifugal compressor and heated to 360°C using high-pressure steam in a heat exchanger. The o-xylene feed is passed through a pump to increase its pressure to 2 bar and subsequently heated and vaporized in heat exchanger. These streams are then mixed. The combined o-xylene and air stream enters a multitubular fixed-bed catalytic reactor. In the reactor, the o-xylene undergoes oxidation reactions to produce the desired product of PA, byproduct maleic anhydride (MA) and products of combustion. All these reactions are highly exothermic, and the temperature of the reactor is controlled by heat exchange with a stream of cooling medium that flows concurrently through the shell-side of the reactor.Using the information given below draw and label a flowchart of the processes involved in production of phthalic anhydride.

C3H6 + C6H6 → C9H12 C3H6 + C9H12 → C12H18 A) Draw and label a flowchart of the process and do the degrees-of-freedom analysis based on atomic species balances, taking a basis of 100 mol C9H12 produced. Assume that the feed contains only propylene and benzene, and that all of the propylene is consumed in the reaction. B) The reactor is designed to yield a 20% conversion of benzene and a selectivity of 10 mol C9H12/mol C12H18, with a negligible...
