Solvent Loss with solvent evaporation loss rate of 3.25 kg / hr: a worked example

This worked example runs the solvent loss numbers for a tougher week than the baseline: solvent evaporation loss rate of 3.25 kg / hr instead of the typical 6.5 kg / hr. Estimate solvent or carrier loss during fragrance, flavor, extract, dilution, or aroma chemical handling.

The inputs for this scenario

  • Solvent evaporation loss rate: 3.25 kg / hr (the input this scenario stresses; the baseline uses 6.5)
  • Open vessel handling and processing time: 9 hr (held at the documented default)
  • Solvent or carrier unit cost: 2.8 $ / kg (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Solvent Loss consumed = solvent loss rate × open handling or processing time.
  • Solvent Loss quantity works out to 29.25 units at these inputs, and this is the headline figure for the scenario.
  • Solvent Loss cost works out to 81.9 $ at these inputs.
  • Open handling or processing time works out to 9 hr at these inputs.
  • Solvent or carrier cost works out to 2.8 $ / unit at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where solvent evaporation loss rate sits at 6.5 kg / hr and the headline result is 58.5 units, this scenario comes in 50% below the baseline at 29.25 units.
  • Use it when scoping a new compounding line, justifying closed-transfer or lidded-vessel upgrades, or attributing batch cost variance to evaporation rather than yield. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
