How does carbon capture work?

Chemical Stripping

Another carbon capture method involves passing exhaust gasses through chemicals that pull out the CO2, according to the University of Strathclyde in the U.K. [source: University of Strathclyde, UK]. In this process, flue gasses from a power plant go through a filterlike "scrubber" containing an industrial solvent like Selexol. The solvent greedily sucks up the CO2 and then the solution passes through a heat source, boiling off the solvent and leaving the pure, liquid CO2 behind.
