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: It helps in understanding the partitioning behavior of the carrier liquid between two immiscible phases.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( K_{CarrierLiq} \) — Distribution Coefficient of Carrier Liquid
• \( Υ_{aR} \) — Activity Coefficient of Carrier Liq in Raffinate
• \( Υ_{aE} \) — Activity Coefficient of Carrier Liquid in Extract

Explanation: The distribution coefficient is calculated by dividing the activity coefficient in the raffinate phase by the activity coefficient in the extract phase.

3. Importance of Distribution Coefficient

Details: This coefficient is crucial in liquid-liquid extraction processes to determine the efficiency of separation and the partitioning of components between phases.

4. Using the Calculator

Tips: Enter the activity coefficients for both raffinate and extract phases. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What does the distribution coefficient tell us?
A: It indicates how a carrier liquid will distribute itself between two immiscible liquid phases at equilibrium.

Q2: What's a typical value range for this coefficient?
A: Values typically range from 0.1 to 10, depending on the system and conditions.

Q3: How are activity coefficients determined?
A: They are usually determined experimentally or calculated using thermodynamic models.

Q4: What affects the distribution coefficient?
A: Temperature, pressure, and the nature of the solvent system all affect the coefficient.

Q5: Can this coefficient be greater than 1?
A: Yes, it simply means the carrier liquid prefers the extract phase over the raffinate phase.
