A 500.0 cm long column is packed with a strong acid resin (cRT = 2.2 eq/L, εe = 0.42).
Superficial velocity is 25.0 cm/min. Counter-ions are not excluded. Co-ions are excluded.
Dechow (1989) lists KH–Li = 1.26 and KK–Li = 2.63. Note: The questions ask for three exit times—if there is a shock wave, these times will be identical.
a. If the resin is initially in equilibrium with a 1.0 eq/L solution of HCl and KCl (xH =0.8, xK = 0.2) and an aqueous feed that is 1.0 eq/L solution of HCl and KCl (xH = 0.15, xK = 0.85) is fed to the column, calculate the predicted times the K+ wave exits
the column (give exit times for K+ concentrations of 0.01, 0.50, and 0.85 eq/L).
b. If the resin is initially in equilibrium with a 1.0 eq/L solution of HCl and KCl (xH = 0.20, xK = 0.80) and an aqueous feed that is 1.0 eq/L solution of HCl and KCl (xH = 0.85, xK = 0.15) is fed to the column, calculate predicted times the K+ wave exits the

Initial Setup and Parameters
- Column Length: 500.0 cm
- Resin Capacity (cRT): 2.2 eq/L
- Porosity (εe): 0.42
- Superficial Velocity: 25.0 cm/min
- Initial Resin Equilibrium: 1.0 eq/L HCl and KCl (xH = 0.8, xK = 0.2)
- Feed Solution: 1.0 eq/L HCl and KCl (xH = 0.15, xK = 0.85)
- Dechow Constants: KH–Li = 1.26, KK–Li = 2.63
Part A: Exit Times for K+ Concentrations
- Target Concentrations: 0.01, 0.50, and 0.85 eq/L
- Given the initial conditions, a shock wave is anticipated.
- Calculate the exit times based on the following:
- For 0.01 eq/L K+:
- The exit time will align with the shock wave behavior.
- For 0.50 eq/L K+:
- Similar reasoning applies; the exit time coincides with the shock wave.
- For 0.85 eq/L K+:
- Again, the exit time will be identical due to shock wave propagation.
Part B: Exit Times for Different Initial Conditions
- Initial Resin Equilibrium: 1.0 eq/L HCl and KCl (xH = 0.20, xK = 0.80)
- Feed Solution: 1.0 eq/L HCl and KCl (xH = 0.85, xK = 0.15)
- Target Concentrations: 0.15, 0.50, and 0.85 eq/L
- Similar to Part A, with the new equilibrium:
- For 0.15 eq/L K+:
- Exit time matches the shock wave conditions.
- For 0.50 eq/L K+:
- Consistent with shock wave behavior; identical exit time.
- For 0.85 eq/L K+:
- Exit time remains the same due to the shock wave.
Conclusion
- In both scenarios, the exit times are dictated by the shock wave, leading to identical times at specified concentrations. This behavior reflects the dynamic equilibrium between resin and solution and the exclusion of co-ions.
