Industrial CO₂ capture systems remove carbon dioxide from industrial process emissions—cement production, steel manufacturing, chemical plants, refineries—preventing atmospheric release and enabling CO₂ utilization or sequestration. Capturing industrial emissions is essential for decarbonizing hard-to-abate sectors.

Capture technologies include post-combustion capture using chemical solvents, pre-combustion capture producing hydrogen and concentrated CO₂, and oxy-fuel combustion generating high-purity CO₂ streams. Technology selection depends on CO₂ concentration, process characteristics, existing infrastructure, and capture economics.

Industrial CO₂ capture equipment includes absorber columns, solvent regeneration systems, compression trains for CO₂ transport, heat integration equipment, and auxiliary systems. Fabrication must accommodate corrosive amine solutions, high-pressure CO₂ streams, and thermal cycling during operation.

Unlike power plant capture, industrial capture faces diverse process conditions and often requires custom engineering for specific applications. Integration with existing facilities presents additional complexity including space constraints and operational coordination.
