1. What is Distribution Coefficient of Carrier Liquid?

Definition: The distribution coefficient of Carrier Liquid is defined as the concentration of carrier liquid in the extract phase divided by the concentration of carrier liquid in the raffinate phase.

Purpose: This parameter is crucial in liquid-liquid extraction processes to understand how the carrier liquid distributes between the two phases.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ K_{CarrierLiq} = \frac{y_A}{x_A} \]

Where:

\( K_{CarrierLiq} \) — Distribution coefficient of carrier liquid
\( y_A \) — Mass fraction of carrier liquid in the extract phase
\( x_A \) — Mass fraction of carrier liquid in the raffinate phase

Explanation: The ratio of the mass fractions in the two phases gives the distribution coefficient, which indicates the preference of the carrier liquid for one phase over the other.

3. Importance of Distribution Coefficient

Details: This coefficient is essential for designing and optimizing separation processes in chemical engineering, particularly in liquid-liquid extraction systems.

4. Using the Calculator

Tips: Enter the mass fractions of carrier liquid in both extract and raffinate phases. Both values must be between 0 and 1, and the raffinate fraction cannot be zero.

5. Frequently Asked Questions (FAQ)

Q1: What does a distribution coefficient of 1 mean?
A: A value of 1 indicates the carrier liquid distributes equally between both phases.

Q2: What if my distribution coefficient is very high?
A: A high value means the carrier liquid strongly prefers the extract phase over the raffinate phase.

Q3: Can the distribution coefficient be less than 1?
A: Yes, this means the carrier liquid prefers the raffinate phase over the extract phase.

Q4: How is this different from partition coefficient?
A: The distribution coefficient specifically refers to the carrier liquid in ternary systems, while partition coefficient is more general.

Q5: What factors affect the distribution coefficient?
A: Temperature, pressure, and the nature of the solvent system can all influence the distribution coefficient.
