Carbon Capture & CO₂ Compression Equipment worked example

Skid Throughput at 65% expected skid uptime: a worked example

This worked example runs the skid throughput numbers for a tougher week than the baseline: 65% expected skid uptime instead of the typical 90%. Estimate usable CO₂ capture or compression skid throughput after planned operating days, uptime, and acceptance yield are considered.

The inputs for this scenario

  • Rated CO₂ throughput per period: 4 t CO₂ / period (held at the documented default)
  • Planned operating periods: 480 periods (held at the documented default)
  • Expected skid uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Accepted CO₂ delivery yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross rated CO₂ throughput = rated CO₂ throughput per period × planned operating periods.
  • Usable CO₂ skid throughput works out to 1,211 t CO₂ at these inputs, and this is the headline figure for the scenario.
  • Gross rated CO₂ throughput works out to 1,920 t CO₂ at these inputs.
  • Throughput lost to downtime works out to 672 t CO₂ at these inputs.
  • Throughput held or rejected works out to 37.44 t CO₂ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected skid uptime sits at 90% and the headline result is 1,676 t CO₂, this scenario comes in 27.78% below the baseline at 1,211 t CO₂.
  • Use it during capacity planning, offtake contract sizing, or when reconciling why captured tonnes fall short of a nameplate-based forecast. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Usable CO₂ skid throughput: 1,211 t CO₂ (headline result)
  • Gross rated CO₂ throughput: 1,920 t CO₂
  • Throughput lost to downtime: 672 t CO₂
  • Throughput held or rejected: 37.44 t CO₂
