B is the desired product, and X and Y are foul pollutants that are expensive to get rid of. The specific reaction rates are at 27C. The reaction system is to be operated at 27C and 4 atm. Pure A enters the system at a volumetric flow rate of 10 dm3/min. (a) Sketch the instantaneous selectivities (SB/X, SB/Y, and SB/XY =rB⁄(rX+rY)) as a function of the con- centration of CA. (b) Consider a series of reactors. What should be the volume of the first reactor? (c) What are the effluent concentrations of A, B, X, and Y from the first reactor? (d) What is the conversion of A in the first reactor? (e) If 99% conversion of A is desired, what reaction scheme and reactor sizes should you use to max- imize SB/XY?
