Carbon Capture & CO₂ Compression Equipment worked example

Skid Throughput at 99% expected skid uptime: a worked example

What does the result look like when expected skid uptime reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when skid throughput in carbon capture and co₂ compression equipment is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Rated CO₂ throughput per period: 4 t CO₂ / period (unchanged)
  • Planned operating periods: 480 periods (unchanged)
  • Expected skid uptime: 99 % (raised for this scenario; the documented default is 90)
  • Accepted CO₂ delivery yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross rated CO₂ throughput = rated CO₂ throughput per period × planned operating periods) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 t CO₂ for usable co₂ skid throughput, the number this scenario is built around.
  • At this operating point the engine returns 1,920 t CO₂ for gross rated co₂ throughput.
  • At this operating point the engine returns 19.2 t CO₂ for throughput lost to downtime.
  • At this operating point the engine returns 57.02 t CO₂ for throughput held or rejected.

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 10% above the baseline at 1,844 t CO₂.
  • A figure at this level is achievable when expected skid uptime is genuinely sustained, not just peaked for a shift. It treats uptime and yield as flat averages over all periods; a skid with a few long outages or a seasonal purity problem needs period-by-period modeling to avoid masking the timing of losses.

Results at a glance

  • Usable CO₂ skid throughput: 1,844 t CO₂ (headline result)
  • Gross rated CO₂ throughput: 1,920 t CO₂
  • Throughput lost to downtime: 19.2 t CO₂
  • Throughput held or rejected: 57.02 t CO₂
