Removal of HCl from Propylene Recycle: propose an absorber column to remove HCl from the propylene distillate
Question:
Removal of HCl from Propylene Recycle: propose an absorber column to remove HCl from the propylene distillate product that you obtained in problem 4 of HW6. The absorber should operate at 10 °C and atmospheric pressure using pure water as the absorbent. If possible, the "spent absorbent" stream should contain 19.4 mol% HCl to meet the product purity requirements. Equilibrium data for absorption of HCl into water is included in the textbook problem 12.D8. Determine the flowrates and compositions of the product streams and the number of equilibrium absorption stages are required. Using the graphical method for a concentrated solution. You should NOT use ASPEN for this problem:
