Definition: This calculator determines the amount of solute entering a column in the underflow based on the solute leaving the column and the fractional solute discharge.
Purpose: It helps in continuous leaching operations to calculate solute quantities in underflow streams.
The calculator uses the formula:
Where:
Explanation: The solute leaving in the underflow is divided by the fractional solute discharge to determine the solute that entered the column.
Details: Accurate calculation of solute quantities is crucial for mass balance in continuous leaching processes and process optimization.
Tips: Enter the solute amount in underflow leaving (kg/s) and the fractional solute discharge (0-1). Both values must be > 0.
Q1: What is fractional solute discharge?
A: It's the ratio of solute exiting the stage to that entering the stage in continuous leaching.
Q2: What are typical values for fractional solute discharge?
A: Values range between 0 and 1, typically around 0.1-0.9 depending on the leaching efficiency.
Q3: How is this different from overflow calculations?
A: This specifically deals with the underflow stream, which typically contains more solids than the overflow.
Q4: What units should be used?
A: Consistent mass flow units (like kg/s) should be used for solute quantities.
Q5: Can this be used for batch processes?
A: No, this formula is specifically for continuous leaching operations.
