Henry constant at T = 5C, H = 1.87 MPa, at T = 15C, H = 2.71MPa and at T= 25C, H = 3.57MPa The flowrate of the desulfurised syngas that is directed in the absorption column is 1200 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. 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.
