CO2 can be captured by either applying oxyfuel or pre-combustion and post-combustion processes using amine or membrane based processes. The common ground for any CCS technology – whether they are solvent (amine based) or membranes (PSA) based – is that compressors are essential to boost the low pressure wet CO2 gas to either transport or nearby industries. Carbon Capture technologies supported by Atlas Copco turbocompressors: - Oxy-fuel - Pre-combustion - Post-combustion
Once CO2 is captured it can be re-used as a feedstock for various processes (i.e., in the chemical/petrochemical industry). Also, by compressing it to supercritical levels (sCO2) it can be used as a working fluid.
Rather than expelling harmful CO2 into the environment, it can be stored for future energy use, or stored deep underground in certain geological formations. This ensures the safe sequestration of CO2 while keeping it out of our environment.
