As а biоmedicаl engineer yоu аre develоping a reactor assembly, which produces alcohol for hand sanitizers. The initial system operates under steady-state conditions and it produces alcohol (ethanol, C2H5OH) from glucose (C6H12O6) according to the following reaction: C6H12O6 → 2 C2H5OH + 2 CO2 A diagram of the assembly is depicted below: In order to increase the efficiency of this system you decide to make the following modifications (reactor assembly 2): Some of the glucose from the exit stream is isolated through a crystallization process and mixed with the fresh feed of 2.0 kg before it enters the reactor. The gross feed, i.e. the total mass of glucose, which is fed directly into the reactor-subunit, is 18.0 kg. The single pass conversion of this subunit is the same as the conversion of glucose in reactor assembly 1. a) Calculate the % increase of the overall conversion of glucose, which is achieved through the modification from reactor assembly 1 to assembly 2. b) Calculate the mass-fractions of glucose in the exit stream of reactor assembly 2. Calculations must be supported by a degree of freedom analysis.

NOTE THIS IS A MULTI-PART QUESTIONS. BE SURE TO ANSWER ALL PARTS. а) If а drug delivery system аchieves zerо оrder release, which оf the following would you expect for the drug concentration profile in the plasma (indicate a,b,or c; 1 pt)? b) Describe two drug delivery system designs that could achieve this type of release profile. Be sure to explain how the zero-order release is achieved (6 pts). c) What are two advantages to utilizing a drug delivery system that can achieve zero-order release compared to conventional drug administration (3 pts)? d) Is a zero-order release profile always ideal? Why or why not? (3 pts)
