Definition: This calculator determines the amount of solute remaining in a solid material after multiple washing stages in batch leaching operations.
Purpose: It helps chemical engineers and process designers optimize washing processes to achieve desired solute removal efficiency.
The calculator uses the formula:
Where:
Explanation: The formula calculates how much solute remains after each washing stage based on the solvent ratio and number of washings.
Details: Accurate calculation helps determine the number of washing stages needed to achieve target solute concentration, optimizing process efficiency and solvent usage.
Tips: Enter the original solute weight, solvent ratio (β), and number of washings. All values must be positive numbers.
Q1: What does β (beta) represent?
A: β is the ratio of solvent decanted to solvent remaining in the solid after each washing stage.
Q2: How does increasing washings affect solute removal?
A: More washings exponentially decrease the remaining solute, following the power law in the formula.
Q3: What's a typical β value?
A: β typically ranges from 1 to 5, depending on the solid-liquid separation efficiency.
Q4: Can this be used for continuous washing?
A: No, this formula specifically applies to batch washing operations.
Q5: How accurate is this calculation?
A: It provides theoretical values assuming perfect mixing and equilibrium in each stage.
