Description
Calculate nominal saturation capacity and excess supplied solute.
Engineering scalar terms depend on mass versus mole bases, absolute state variables and the process boundary. A vapor/liquid ratio differs from a reaction equilibrium constant, space time differs from a measured residence-time distribution, and fouling-area scaling preserves a specified heat-transfer product. Supplied terms do not validate an actual process.
Calculate nominal saturation capacity and excess supplied solute.
When to use this tool
Use Crystallizer Solubility Mass Difference when you already have dissolvedSoluteMass, solventMass, solubilityMassPerSolventMass and need to calculate nominal saturation capacity and excess supplied solute.
How to use the tool and how it works
- Enter dissolvedSoluteMass, solventMass, solubilityMassPerSolventMass. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read saturationCapacity, excessSoluteMass. Use the output convention below.
Require solute/solvent masses and solubility>=0; capacity=solventMass*soluteMassPerSolventMass, excess=max(0,dissolved-capacity).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| dissolvedSoluteMass | Dissolved Solute Mass | Required. Finite number; minimum 0. |
| solventMass | Solvent Mass | Required. Finite number; minimum 0. |
| solubilityMassPerSolventMass | Solute/solvent mass ratio, not solute/total-mixture fraction. | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| saturationCapacity | Saturation Capacity | Required. Finite number. |
| excessSoluteMass | Excess Solute Mass | Required. Finite number. |

}Limitations and assumptions
- Solubility uses solute/solvent mass, not solute/solution mass fraction. No equilibrium, temperature, crystallization kinetics, yield or appropriate process is determined.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use complete material, energy, phase and equipment models with verified operating conditions. Check concentration bases, gas reference states and measurement uncertainty before applying local ratios or balances to process design or operation.
