Carbon Capture & CO₂ Compression Equipment worked example
Solvent Makeup Cost at 92% capture train cost share: a worked example
What does the result look like when capture train cost share reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when solvent makeup cost in carbon capture and co₂ compression equipment is being put through a carbon capture and co₂ compression equipment weighted-cost review.
The inputs for this scenario
- Solvent makeup required: 100 gal (unchanged)
- Delivered solvent price: 45 $ / gal (unchanged)
- Capture train cost share: 92 % (raised for this scenario; the documented default is 80)
- Fixed solvent handling cost: 250 $ (unchanged)
Working through the calculation
- Applying the documented formula (Variable solvent makeup cost = solvent makeup required × delivered solvent price × capture train cost share) to the inputs above produces each figure below.
- At this operating point the engine returns 4,390 $ for total solvent makeup cost, the number this scenario is built around.
- At this operating point the engine returns 43.9 $ / piece for solvent makeup cost per gallon.
- At this operating point the engine returns 4,140 $ for variable solvent makeup cost.
- At this operating point the engine returns 250 $ for fixed solvent handling cost.
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 14.03% above the baseline at 4,390 $.
- A figure at this level is achievable when capture train cost share is genuinely sustained, not just peaked for a shift. The cost share is a flat allocation factor; it cannot capture transient losses from foaming, upsets or a reclaimer campaign that hit one train disproportionately.
