Demonstrate how each specific enthalpy was calculated, from the reference state to the process state. Be thorough to the fullest. This is a material-energy balance. The answers are H(1) = 35.7 KJ/kmol, H(2) = 32.0 KJ/kmol, and H(3) = -1.26 KJ/kmol.

- 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? (Hint: set up a mass balance) 0.25 , * 1 2 b) What should be the flow rate of resin (in kg/h) into the second column (B2) if your overall process needs to remove 99% of the protein?arrow_forward6) Instead of moving bed adsorption, you decide to try fixed bed adsorption with a different resin for removal of your protein. 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. If all else but length of the column is held constant, how long will you be able to run the column before breakthrough?arrow_forward2) 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.arrow_forward
