During the separation and processing phase, the CO₂ enriched solvent is pumped to a stripper to regenerate CO₂ gas, and lean solvent. CO₂ gas is then treated, and prepared for sequestration or industrial commercial usage.

Stripper

Howden is a world leader in Mechanical Vapour Compressor (MVR) technologies, which is a key element in the stripping of CO₂ from the solvent that captured the Carbon Dioxide in previous stages. Howden Turbo Compressors/blowers form the basis of the MVR system which enables CO₂ to be extracted for re-use.

Scrubbing, Drying and Adsorption

Once the CO₂ has been extracted, it is compressed using a Howden screw or centrifugal compressor in order to remove any remaining water or chemicals from the gas stream using Pressure Swing Adsorption (PSA).

Liquefaction

Prior to sequestration or usage, the CO₂ is condensed. The condenser will require a Howden screw compressor for the refrigeration cycle.
