How do you calculate total solvent makeup cost?

Multiply makeup volume by delivered price and by the train's cost share, then add the fixed handling cost. For 100 gal at $45/gal with an 80% share, the variable cost is $3,600; adding $250 fixed gives $3,850 total.

What does the capture train cost share represent?

It is the fraction of shared solvent makeup you allocate to this train, expressed as a percent. If a common inventory feeds several trains, an 80% share charges this train 80% of the variable makeup spend.

Why include a fixed solvent handling cost?

Storage, pumping, filtration, reclaiming and waste disposal cost money even when makeup volume is low. The $250 fixed term captures that baseline so the total reflects real cost, not just gallons bought.

What is a typical amine solvent makeup rate?

It varies widely with solvent type and flue gas quality, but well-run MEA plants often target makeup in the low single-digit kg per tonne CO₂. Use this calculator with your measured gallons rather than a textbook figure.

How do I reduce solvent makeup cost?

Cut degradation by controlling oxygen ingress and reclaimer scheduling, reduce entrainment with better demisters, and recover solvent from washwater. Each lowers the makeup volume that drives the variable term.

Carbon Capture & CO₂ Compression Equipment calculator

Solvent Makeup Cost Calculator

Amine and other liquid-solvent CO₂ capture plants lose solvent to evaporation, entrainment, thermal and oxidative degradation, and reclaimer bottoms, so fresh solvent must be added to keep absorber chemistry on spec. This calculator combines the variable cost of that makeup, scaled by the share allocated to a given capture train, with the fixed cost of handling, storage and reclaiming. Operations and finance teams use it to allocate solvent OPEX accurately when a solvent inventory serves several trains or units. Getting the cost share right matters because solvent makeup is frequently the second-largest consumable after steam.

What this calculator does

Estimate solvent makeup cost for an amine or liquid-solvent capture loop after degradation, carryover, reclaiming loss, or blowdown.
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.
It scales solvent makeup volume by delivered price and a capture-train allocation factor, then adds a fixed handling cost to give the total.

Formula used

Variable solvent makeup cost = solvent makeup required × delivered solvent price × capture train cost share
Total solvent makeup cost = variable solvent makeup cost + fixed solvent handling cost

Inputs explained

Solvent makeup required:
Delivered solvent price:
Capture train cost share:
Fixed solvent handling cost:

How to use the result

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.
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.

Current U.S. benchmarks

Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
