Solvent Makeup Cost at 58% capture train cost share: a worked example

This worked example runs the solvent makeup cost numbers for a tougher week than the baseline: 58% capture train cost share instead of the typical 80%. Estimate solvent makeup cost for an amine or liquid-solvent capture loop after degradation, carryover, reclaiming loss, or blowdown.

The inputs for this scenario

  • Solvent makeup required: 100 gal (held at the documented default)
  • Delivered solvent price: 45 $ / gal (held at the documented default)
  • Capture train cost share: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed solvent handling cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable solvent makeup cost = solvent makeup required × delivered solvent price × capture train cost share.
  • Total solvent makeup cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Solvent makeup cost per gallon works out to 28.6 $ / piece at these inputs.
  • Variable solvent makeup cost works out to 2,610 $ at these inputs.
  • Fixed solvent handling cost works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where capture train cost share sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • Use it when one solvent inventory or reclaiming system is shared and you need to charge a fair portion to a specific train or product. 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.

Results at a glance

  • Total solvent makeup cost: 2,860 $ (headline result)
