Do question 9 please! Question 7 Is just there for reference!!
7) You are tasked with separating two proteins by ion exchange chromatography on a 30 cm long
column with an inner diameter of 2 cm. The resin has a diameter of 100 μm and a void fraction
of 0.3, and your mobile phase flows through the column at a rate of Q = 5 cm³/min. The Van
Deemter coefficients A, B, and C have been determined to be 0.0228 cm, 0.0036 cm²/min, and
0.00053 min, respectively, for both proteins. Protein A elutes from the column with an average
retention time of 27 min and standard deviation of 0.8 min. Protein B elutes from the column.
with an average retention time of 33.8 min and standard deviation of 1.0.

- 1 5) You are asked to design a moving bed adsorption process using two columns (see the figure below). Your feed contains 100 mg/L protein and flows through both columns at 4 m³/h. Fresh resin enters the bottom of both columns (resin does not flow from the bottom column to the top column). The maximum resin flow rate that your pumps can comfortably handle is 120 kg resin/h. Experimental data suggest that the adsorption equilibrium can be modeled as qi=4ci where qi is in g protein/kg resin and c; is in g protein/L broth. (Pay attention with units!) a) What is the lowest concentration of proteins that you could get in the effluent from column 1 (indicated by the *) in mg/L?

Your column is 25 cm long with an inner diameter of 5 cm. The resin packed in the column has a density of 1.5 g/cm³ and a void fraction of 0.25. Equilibrium data suggests that the protein binding to the column follows a Langmuir isotherm with an Stot = 6.25 g protein/kg resin and Keq = 2.58 L broth/g protein. The feed contains 100 mg/L protein and flows through the column at 500 mL/h. The calculated binding capacity of the column under these conditions is 945 mg protein. a) After 17.7 h, you detect an unacceptable level of protein in the column effluent. What is the length of unused bed? b) After deciding that this process will work well for separation, you need to scale up to a 1 m long column with the same diameter.

- Chemical Engineering Use the psychrometric chart and demonstrate the linear interpolation method to obtain -0.52 KJ/KgDA. 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.
