Adsorption Break Through Curve Calculations

Adsorption breakthrough curve calculations are crucial in designing and optimizing adsorption processes. They help determine the optimal bed height and flow rate to prevent breakthrough and ensure efficient adsorption.

1. Enter the required parameters in the calculator above.
2. Click the “Calculate” button.
3. View the results and chart below the calculator.

The breakthrough curve is calculated using the following formula:

C_b/C₀ = 1 – exp(-(3k_fC₀t)/(ρ_p(1-ε)))

Where:

• C_b/C₀ is the breakthrough ratio
• k_f is the film mass transfer coefficient
• C₀ is the initial concentration
• t is the time
• ρ_p is the particle density
• ε is the bed porosity

Comparison of Adsorption Kinetics Models

Model	R-Squared	Chi-Squared
Pseudo-First Order	0.95	0.005
Pseudo-Second Order	0.98	0.002

• Always ensure the bed height is sufficient to prevent breakthrough.
• Consider using a higher flow rate to reduce the breakthrough time.
• Regularly clean and regenerate the adsorbent to maintain its capacity.

What is the optimal flow rate?

The optimal flow rate depends on the specific adsorption process and should be determined through experimentation.

How can I prevent breakthrough?

Increasing the bed height or reducing the flow rate can help prevent breakthrough.
