Pre-selection for positive-displacement process gas compressors
APPLICATION

Compressors for CO₂ Capture and Pipeline Feed

From capture-plant outlet pressure to dense-phase pipeline — the phase sets the duty

Typical capture-plant duty: CO₂ picked up at 10–25 bar(a) after conditioning and boosted across the critical point (73.8 bar) into dense phase for pipeline transport.

What the tool says on this profile

The tool's answer on this profile: Reciprocating (Piston) Compressor. Duty as derived by the engine: 5000 Nm³/h, 20.0 bar(a) → 80.0 bar(a), overall pressure ratio 4.0.

Computed at build time by the same engine the tool runs — this page and the selector cannot disagree. Your duty differs from the profile? Run your own numbers below.

What to watch

  • Whether the stream travels as gas or dense phase is decided here, at the compression train — the pipeline inherits it.
  • Impurities from the capture process (water above all) change both the phase behaviour and the corrosion file; stream composition belongs in the RFQ.
  • Very large single-train duties move to integrally geared centrifugal machines — outside this site's positive-displacement coverage.
