2) A bioprocess stream contains two components: 60 g/L A (the desired bioproduct) and 40 g/L
B (a contaminant). The partition coefficients in an extraction process are KA = 14.0 and KB = 0.5.
If the stream is fed into a 5-stage countercurrent extractor at 25 L/min and solvent enters at 5
L/min, calculate the amount of each component in the extract phase at the outlet of the extractor.
What flow rate (Q, in L/min) will give the maximum resolution if you scale up the process in
problem 7 to a column with a diameter of 50 cm? (Use the conditions in the problem
statement, not the optimal flow conditions calculated in the problem).
You are asked to separate two proteins via size exclusion chromatography. Your column is 5
cm in diameter and 25 cm in length. You add 50 g (dry weight) of Sephacryl gel (density = 1.25
g/cm³) to the column. The volume outside of the gel and pores is 77 cm³. The column operates at
a flow rate of 1 mL/min to not compress the resin. The average retention times of proteins A and
B are 244.5 and 273 min, respectively. Under the given conditions, you calculate that there are
1600 theoretical plates in the column. (This problem continues onto the next page).
a) What is the volume inside of the pores?
b) What are the elution limits of this system (i.e., what re the minimum and maximum
volumes that particles will elute in)?
c) What are the gel partition coefficients of proteins A and B for this system?
d) What are the peak widths for both proteins?
e) Assuming the peak widths are 22 mL and 28 mL for proteins A and B, respectively (these
values are not necessarily correct), what is the…

This is the enthalpy deviation. The exercise is uploaded below.arrow_forwardChemical Engineering Use the psychrometric chart. The remaining curves on the psychrometric chart are almost vertical and convex to the left, with labeled values (on Figure 8.4-1) of 0.05, 0.1, 0.2, and so on. (The units of these numbers arekJ/kg DA). Thesecurves are usedto determine theenthalpyof humid air that is not saturated. The procedure is as follows: (a) locate the point on the chart corresponding to air at its specified condition; (b) interpolate to estimate the enthalpy deviation at this point; (c) follow the constant wet-bulb temperature line to the enthalpy scale above the saturation curve, read the value on that scale, and add the enthalpy deviation to it. Also, you will see the exercise on the piece of paper.arrow_forward
