CO₂ Compressor: The Essential Equipment for Carbon-Neutral Industries

The carbon dioxide compressor is transitioning from a traditional industrial auxiliary to a core piece of equipment in the Carbon Capture, Utilization, and Storage (CCUS) value chain. This comprehensive guide explores its technology, applications, and market trends, offering vital information for industrial procurement and system design.

What is a CO₂ Compressor?

A CO₂ compressor is a specialized machine engineered to handle high-density, easily liquefiable gas. Unlike standard air compressors, it must address unique technical challenges:

  • Unique Critical Point: CO₂ has a critical temperature of 31.1°C (87.98°F) and a critical pressure of 7.38 MPa (1070 psi).

  • Phase Transition Control: Precise management of gas liquefaction during compression is required.

  • Material Compatibility: Construction must prevent low-temperature and chemical corrosion, especially from carbonic acid formation.

  • High-Seal Integrity: Supercritical CO₂ is highly permeable, demanding advanced sealing solutions.
