Description

Return one-stage liquid partition concentrations.

A process stream can be described on mass, mole, phase or solvent bases, which are not interchangeable. Lever rules, partition factors and operating-line terms assume compatible composition definitions and an appropriate physical model; a local balance does not determine equilibrium properties or a complete separation design.

Return one-stage liquid partition concentrations.

When to use this tool

Use Liquid Liquid Partition One Stage Term when checking the stated stream composition, phase or separation-model term.

How to use the tool and how it works

  1. Enter soluteAmount, aqueousVolume, organicVolume, distributionRatio. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read aqueousConcentration, organicConcentration, extractedFraction. Use the output convention below.

Return one-stage liquid partition concentrations. Require nonnegative soluteAmount/organicVolume/distributionRatio and aqueousVolume > 0; Caq = amount/(Vaq+D*Vorg), Corg = D*Caq, extractedFraction = D*Vorg/(Vaq+D*Vorg).1

Limitations and assumptions

  • D is Corganic/Caqueous; this assumes compatible volumes, equilibrium, constant D and no volume change or chemical reaction.
  • 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 verified equilibrium and material-property data on consistent bases and solve the complete process model for actual separation or equipment decisions.
