article imageMaking power plants more 'green'? A carbon scrubber unveiled

By Tim Sandle     Jun 30, 2013 in Environment
Scientists have unveiled a "plug-and-play” carbon dioxide scrubbing system, designed to remove a high proportion of carbon emissions from power plants.
The device is an electrochemical carbon dioxide scrubber system, which has been designed to reduce the carbon emissions produced by power plants, according to the Environmental Leader.
The device uses chemical compounds called amines. These chemicals bind with the carbon dioxide found within the power plant’s emission stream. This means that the gasses released into the environment contain considerably lower levels of carbon (the researchers behind the device are aiming for a 90% reduction).
The amines that bind with the carbon revert to liquid form and they can be collected and the carbon can then be disposed of safely without it entering into the atmosphere. The original amine molecules can then be regenerated and reused.
The new invention could help with the new aim of the U.S. Environment Protection Agency which which will shortly issue proposed carbon emissions limits for existing powers plants by June 2014
The new system has been developed by the Massachusetts Institute of Technology and it is designed to be fitted relatively easily to any existing power plant. The device has been presented in a paper published in the journal Energy & Environmental Science. The paper is titled "Post-combustion carbon dioxide capture using electrochemically mediated amine regeneration".
