1. What is Mass Ratio of Solvent in Extract Phase?

Definition: The Mass Ratio of Solvent in Extract Phase is the ratio of mass of solvent in the extract phase to the mass of solute plus carrier liquid in the extract phase.

Purpose: This calculation is important in chemical engineering for liquid-liquid extraction processes in ternary mixtures.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Z = \frac{yB}{yA + yC} \]

Where:

\( Z \) — Mass Ratio of Solvent in Extract Phase
\( yB \) — Mass Fraction of Solvent in the Extract
\( yA \) — Mass Fraction of Carrier Liquid in the Extract
\( yC \) — Mass Fraction of Solute in the Extract

Explanation: The formula calculates the relative amount of solvent compared to the other components in the extract phase.

3. Importance of Mass Ratio Calculation

Details: This ratio helps in understanding the composition of the extract phase and is crucial for designing and optimizing separation processes.

4. Using the Calculator

Tips: Enter the mass fractions of solvent (yB), carrier liquid (yA), and solute (yC) in the extract phase. All values must be between 0 and 1, and the sum of yA and yC must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical range for Z?
A: The value of Z varies depending on the system, but typically ranges from 0.1 to 10 in most extraction processes.

Q2: What if yA + yC equals zero?
A: This would mean there's no carrier liquid or solute in the extract phase, which is physically impossible in a ternary mixture. The calculator requires yA + yC > 0.

Q3: How do I determine the mass fractions?
A: Mass fractions are typically determined through experimental analysis or from phase equilibrium data for the specific ternary system.

Q4: What units are used in this calculation?
A: The calculation is dimensionless since it uses mass fractions (ratio of masses).

Q5: Can this be used for other phase ratios?
A: Similar principles apply, but the exact formula would differ for calculating ratios in the raffinate phase or for different component combinations.
