In the following calculations, select the and = based on the last two digits of your student number respectively. For example, if your student number is 12345678, then your is 7 and your = is 8. If the two numbers are identical, then work your way to the left in your student number to the next non-identical number. The flowrate of the desulfurised syngas that is directed in the absorption column is 6D5= kmol/h and contains 20% of CO2 mol-% which we want to remove by 90%, the remainder 80% comprises of H2 (60%), CO (10%) and 2 (10 %-mol) which can be assumed to be insoluble in DEPG. The DEPG solvent that enters the column is lean Answer all of the questions below, stating clearly and briefly any assumptions made. a) Henry's constant for CO2 in DEPG for different temperatures is given at the end of the brief. Calculate and plot in a single graph the equilibrium line at T = 5C, 15C, and 25C when the operating pressure of the column is P = 30 bar and P = 60 bar. Briefly discuss the impact of (P, T) conditions on the separation and which of the pre-specified (P, T) conditions you would choose and why.
