Solvent Loss Cost at 98% unrecovered loss share: a worked example

This scenario runs the solvent loss cost calculation on the strong side: 98% unrecovered loss share, with every other input held at its documented default. an environmental or operations manager needs to budget or compare solvent loss cost

The inputs for this scenario

  • Solvent lost to evaporation and drag-out: 420 gal (unchanged)
  • Virgin solvent replacement cost: 18.5 $ / gal (unchanged)
  • Unrecovered loss share: 98 % (raised for this scenario; the documented default is 85)
  • Cleanup, disposal, or handling fees: 950 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable cost = solvent lost × solvent replacement cost × unrecovered loss share) to the inputs above produces each figure below.
  • At this operating point the engine returns 8,565 $ for total solvent loss cost, the number this scenario is built around.
  • At this operating point the engine returns 20.39 $ / gal for solvent loss cost per gallon.
  • At this operating point the engine returns 7,615 $ for variable solvent loss cost.
  • At this operating point the engine returns 950 $ for cleanup, disposal, or handling fees.

How this compares with the baseline

  • Against the tool's baseline example, where unrecovered loss share sits at 85% and the headline result is 7,555 $, this scenario comes in 13.37% above the baseline at 8,565 $.
  • Use it to quantify the payback on vapor-recovery, distillation, or improved drag-out controls, and to benchmark solvent cost per gallon across lines. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total solvent loss cost: 8,565 $ (headline result)
  • Solvent loss cost per gallon: 20.39 $ / gal
  • Variable solvent loss cost: 7,615 $
  • Cleanup, disposal, or handling fees: 950 $
