Carbon Capture & CO₂ Compression Equipment worked example

Regeneration Heat Load with regeneration heat duty of 30 kW: a worked example

Push regeneration heat duty up to 30 kW and the picture changes. This example computes every intermediate figure at that operating point. Use it when regeneration heat load in carbon capture and co₂ compression equipment is being quoted and energy is a real chunk of the carbon capture and co₂ compression equipment cost stack.

The inputs for this scenario

  • Regeneration heat duty: 30 kW (raised for this scenario; the documented default is 12)
  • Regeneration operating hours: 8 hr (unchanged)
  • Energy price: 0.12 $ / kWh (unchanged)
  • CO₂ regenerated: 1,000 t CO₂ (unchanged)

Working through the calculation

  • Applying the documented formula (Regeneration heat energy cost = regeneration heat duty × regeneration operating hours × energy price) to the inputs above produces each figure below.
  • At this operating point the engine returns 28.8 $ for regeneration heat energy cost, the number this scenario is built around.
  • At this operating point the engine returns 240 kWh for regeneration heat energy used.
  • At this operating point the engine returns 0.03 $ / piece for regeneration heat cost per tonne co₂.
  • At this operating point the engine returns 3.6 $ / hr for hourly regeneration heat cost.

How this compares with the baseline

  • Against the tool's baseline example, where regeneration heat duty sits at 12 kW and the headline result is 11.52 $, this scenario comes in 150% above the baseline at 28.8 $.
  • It multiplies regeneration heat duty by operating hours and energy price for total heat cost, then divides by CO₂ regenerated for cost per tonne. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Regeneration heat energy cost: 28.8 $ (headline result)
  • Regeneration heat energy used: 240 kWh
  • Regeneration heat cost per tonne CO₂: 0.03 $ / piece
  • Hourly regeneration heat cost: 3.6 $ / hr
