- A process for the microbial synthesis of 1,3-propanediol ( 3 8 2 C H O ) uses an anaerobicfermenter with a selected strain of K. pneumoniae to convert glycerol ( 3 8 3 C H O ) to 1,3-propanediol and acetic acid ( 2 4 2 C H O ). All other byproducts are of negligible concentration.The fermentation and cell growth equation can be written:3 8 3 3 4 7 2 3 8 2 2 4 2 2 2 68 3 3 49 15 15 40 C H O NH C H O N C H O C H O CO H O + → + + + +The continuous fermentation process is set up at 37°C and atmospheric pressure.Anaerobic conditions are maintained by sparging the fermentation broth with N2 at aflowrate of 500 litres per minute. The medium, containing ammonia, is fed at 500 kg perhour, and has a composition of 14% (w/w) glycerol. Suppression of the side reactions isachieved by excess glycerol, so the liquid product contains 3% (w/w) unreacted glycerol.2a. Draw a process diagram.

The gas enters at 10 bar and 350°C and exits at 1 bar and 40°C. The process produces a net amount of work equal to 4500 J/mol and it exchanges an unknown amount of heat with the surroundings. 1.1 Determine the amount of heat exchanged with the surroundings. Is this heat absorbed or rejected by the system? 1.2 Calculate the entropy change of the exhaust gas. 1.3 As a young and ambitious chemical engineer, you seek ways to improve the process. What is the maximum amount of work that you could extract from this system? Assume that the inlet and outlet conditions of the exhaust gas remain the same.
