Carbon Capture & CO₂ Compression Equipment worked example
Heat Exchanger Fouling Loss with added fouling energy penalty of 30 kW: a worked example
Push added fouling energy penalty up to 30 kW and the picture changes. This example computes every intermediate figure at that operating point. Use it when heat exchanger fouling loss 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
- Added fouling energy penalty: 30 kW (raised for this scenario; the documented default is 12)
- Fouled operation runtime: 8 hr (unchanged)
- Energy price: 0.12 $ / kWh (unchanged)
- CO₂ processed during fouled run: 1,000 t CO₂ (unchanged)
Working through the calculation
- Applying the documented formula (Heat exchanger fouling energy cost = added fouling energy penalty × fouled operation runtime × energy price) to the inputs above produces each figure below.
- At this operating point the engine returns 28.8 $ for heat exchanger fouling energy cost, the number this scenario is built around.
- At this operating point the engine returns 240 kWh for added fouling energy use.
- At this operating point the engine returns 0.03 $ / piece for fouling energy cost per tonne co₂.
- At this operating point the engine returns 3.6 $ / hr for hourly fouling energy cost.
How this compares with the baseline
- Against the tool's baseline example, where added fouling energy penalty sits at 12 kW and the headline result is 11.52 $, this scenario comes in 150% above the baseline at 28.8 $.
- It computes the extra energy cost caused by fouling-driven kW, plus the kWh wasted, the hourly cost, and the penalty per tonne of CO2 processed. 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.
