Carbon CaptureC.02
IntroductionIntroductionThe capture of carbon dioxide emissions from existing industriesis essential in realising global targets to decrease emissions ofgreenhouse gases to the atmosphere.
The Carbon Capture technology employed by Process Groupcan be immediately retrofi tted to vir tually any exhaust gassystem, including coal or gas-fi red boilers, gas turbines, blastfurnaces, and cement kiln off-gas.
The process enables carbon dioxide to be selectively absorbedfrom fl ue gas via counter-current contact with a regenerable sol-vent. The solvent is a patented aqueous amine or amino acidsolution specially designed to selectively absorb CO2 from gasstreams.
Each package is designed in close consultation with the clientto ensure the best overall design is achieved.
Design BasisDesign BasisThe design of Carbon Capture Systems is unique to each situ-ation with the overall package design varying to meet eachclients specifi ed process conditions.
Each system is typically designed and built as a complete turn-key package with particular emphasis given to the followingissues:
CO2 product purity Minimum solvent losses Minimum utilities consumption Optimum plant effi ciency & design integrity Compliance with HSE requirements Environmentally conscientious design
Process DescriptionProcess DescriptionIn a typical CO2 Capture package, hot fl ue gas passesthrough the scrubber tower, where it is cooled with coolingwater (1), before being fed to the absorber tower. The gas en-ters near the bottom of the absorber tower and fl ows upwardsthrough the internal packing (2), coming into contact with thesolvent, which enters near the top of the tower, as the solventcascades down through the tower. As the fl ue gas rises throughthe tower the carbon dioxide level is progressively reduced asit is absorbed by the solvent meaning the treated gas ventedfrom the absorber (3) is virtually free of CO2.

Carbon CaptureC.02
From the bottom of the absorber tower the CO2-richsolvent is pumped through the lean-rich exchanger (4)to pre-heat the solvent before it enters the regeneratortower. In the regenerator the solvent is heated via thereboiler (5) to reverse the absorption reaction. As the sol-
vent cascades down through the tower, CO2 is gradu-ally desorbed from the solvent (6). By the time the solventreaches the bottom of the tower virtually all the absorbedCO2 has been released and the CO2-lean solvent iscooled and pumped back to the top of the absorbertower to repeat the process (7).
The desorbed CO2 exits the regenerator tower as apure, water saturated gas from where it is cooled (8)and then passes through the refl ux accumulator to re-move excess water (9). The pure carbon dioxide productgas is then ready for direct use or further processing.
