Solutions in bold Problem 1 An ideal plug flow reactor has a volume of 100 L with a flowrate of 15 L/min and an initial concentration of 22 mol/L. The reaction, A -> B, has k=4.7 L/mol-min. A. Calculate the outlet concentration (mol/L) of reactant from this reactor. 0.0319 mol/L B. Alternatively, a larger mixed flow reactor (500 L) is available using the same processing conditions. Calculate the outlet reactant concentration (mol/L) of this reactor. 0.371 6 mol/L C. Calculate the conversion for each reactor. Which reactor gives a better conversion? Part a. X = 0.998 Part b. X = 0.983 Plug flow reactor gives better conversion. Problem 2 An enzymatic reaction runs in a series of 2 equal volume mixed flow reactors. Given the data below: A. Derive the expression for the outlet concentration (C) for a single mixed flow reactor with an enzymatic reaction occurring as a function of K m , V m , τ m and Co. Data: - V m C r = --------------- K m + C V m = 6.3 mol/L-min K m = 3.2 mol/L C o = 5.6 mol/L τ m = 15.7 min C1 = {-[ K m + τ m V m – Co]+SQRT[(K m + τ m V m – Co)^2 + 4K m Co]}/2 B. Calculate the overall conversion
