How to Use This Calculator
- Enter the Feed Rate in kg/hr and the Feed Concentration as a mass fraction of the key component.
- Enter the Product Flow Rate in kg/hr and the Product Concentration as a mass fraction — these define the desired output.
- Enter the Recycle Rate in kg/hr and Recycle Concentration if a recycle loop exists in the process. Set to 0 if there is no recycle.
- The calculator applies overall and component mass balances to determine the Waste Flow Rate and Waste Concentration.
- Review the Conversion % — the fraction of feed key component that ends up in the product versus waste.
- Check Overall Yield % to assess process efficiency and identify opportunities to reduce waste or improve separation.
