Carbon Capture & CO₂ Compression Equipment worked example

Blower Energy Cost at 92% average blower load share: a worked example

This scenario runs the blower energy cost calculation on the strong side: 92% average blower load share, with every other input held at its documented default. Use it when blower energy 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

  • Blower operating hours: 100 hr (unchanged)
  • Blower energy cost per hour: 45 $ / hr (unchanged)
  • Average blower load share: 92 % (raised for this scenario; the documented default is 80)
  • Fixed blower demand cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable blower energy cost = blower operating hours × blower energy cost per hour × average blower load share) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total blower energy cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for blower cost per operating hour.
  • At this operating point the engine returns 4,140 $ for variable blower energy cost.
  • At this operating point the engine returns 250 $ for fixed blower demand cost.

How this compares with the baseline

  • Against the tool's baseline example, where average blower load share sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • Use it when costing the blower line item of a capture skid, comparing tariff scenarios, or quantifying the energy penalty of running a blower below or above its best-efficiency point. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total blower energy cost: 4,390 $ (headline result)
  • Blower cost per operating hour: 43.9 $ / piece
  • Variable blower energy cost: 4,140 $
  • Fixed blower demand cost: 250 $
