How is cost per ton of CO2 captured actually calculated?

The Capture Cost per Ton calculator sums regeneration heat, compressor and blower energy, solvent or sorbent makeup, and amortized capital, then divides by annual tonnes captured from Capture Efficiency. Energy is usually the dominant term, so it is sensitive to power price and heat source. Post-combustion amine capture commonly lands in a wide band per tonne depending on flue gas CO2 concentration and available low-grade heat.

Why does pushing capture efficiency higher raise cost per ton?

Capture Efficiency shows diminishing returns: moving from 90 to 95 percent capture requires disproportionately more solvent circulation and Regeneration Heat Load per additional tonne. Because Capture Cost per Ton divides rising energy cost by only slightly more CO2, the marginal tonnes are the most expensive. Most projects optimize around 90 percent rather than chasing maximum capture, unless credit or compliance value justifies the energy penalty.

How much power does CO2 compression consume?

The CO2 Compressor Power calculator estimates shaft power from mass flow, suction and discharge pressure, and stage efficiency, typically compressing to 100 to 150 bar for pipeline or storage. Compression is one of the largest parasitic loads on a capture plant. Combine it with Blower Energy Cost, which covers moving flue gas through the absorber against Absorber Pressure Drop, to get the full electrical penalty.

What drives solvent makeup cost in an amine system?

The Solvent Makeup Cost calculator accounts for solvent degradation, thermal breakdown, and entrainment losses per tonne of CO2 processed. Amine degradation from oxygen and SOx in flue gas is a recurring operating cost and can require reclaiming. Model it alongside Heat Exchanger Fouling Loss, since degraded solvent and fouling both raise the Regeneration Heat Load needed to hit the same capture rate.

How do I estimate payback on a capture retrofit?

The Retrofit Payback calculator compares installed capital plus Field Commissioning Cost against annual net benefit, which is Carbon Credit Revenue or compliance value minus operating cost and Downtime Cost. Payback swings heavily on credit price and power cost. Run it with Capture Cost per Ton so you can see the breakeven credit price at which the project turns cash-positive before committing capital.

How much does heat exchanger fouling cost over a run?

The Heat Exchanger Fouling Loss calculator quantifies the extra heat duty needed as fouling degrades the reboiler and cross exchangers between cleanings. Rising heat duty directly increases Capture Cost per Ton and can force reduced throughput. Pair it with Maintenance Interval to find the cleaning frequency where recovered efficiency outweighs Downtime Cost, which is often the largest controllable operating lever on the plant.
