Coal fired power plants are responsible for a significant amount of carbon dioxide emissions.
Opportunities for large scale capture of carbon dioxide exist in electricity production, manufacturing and industrial processes.
High pressure superheated steam from a coal-fired furnace drives the steam turbines that produce electricity.
Expansion of gas in the combustion chamber drives the turbines to produce electricity.
Flue gases pass through a solvent that preferentially absorbs carbon dioxide.
Carbon dioxide diffuses through a membrane and is absorbed by the solvent.
Carbon dioxide passes through the membrane more easily than other gases.
The gas is cooled and only carbon dioxide condenses. The rest of the gas is vented to the atmosphere.
