1. What is Stripping Factor?

Definition: The Stripping Factor is the ratio of slope of operating line of stripping to the equilibrium line. If equilibrium line is a curve, the stripping factor is the average at the two ends.

Purpose: It's a crucial parameter in mass transfer operations that helps determine the efficiency of stripping processes in chemical engineering.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ S = \frac{\alpha \times G_{s(stripping)}}{L_{s(stripping)}} \]

Where:

Explanation: The equilibrium constant is multiplied by the gas flowrate and divided by the liquid flowrate to determine the stripping factor.

3. Importance of Stripping Factor

Details: The stripping factor determines the effectiveness of a stripping operation. A value greater than 1 indicates efficient stripping, while values less than 1 suggest poor stripping efficiency.

4. Using the Calculator

Tips: Enter the equilibrium constant (default 1.5), gas flowrate (mol/s), and liquid flowrate (mol/s). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does the stripping factor indicate?
A: It indicates the efficiency of the stripping process. S > 1 means effective stripping, S = 1 is the minimum for any stripping to occur, and S < 1 means poor stripping.

Q2: What are typical values for the equilibrium constant?
A: This varies by system but typically ranges from 0.5 to 5.0 for common chemical systems.

Q3: How do flowrates affect the stripping factor?
A: Higher gas flowrates increase the stripping factor, while higher liquid flowrates decrease it.

Q4: What units should be used for flowrates?
A: The calculator uses mol/s, but any consistent molar flow units can be used as long as both flowrates are in the same units.

Q5: Can this be used for absorption calculations?
A: Yes, the absorption factor is simply the reciprocal of the stripping factor (A = 1/S).
