CCC: Cryogenic Carbon Capture

Cryogenic carbon capture, patent pending, is used to capture CO2 from the emissions being produced by power plants. The gases produced by these power plants is filtered so that a nearly pure stream of CO2 can be separated from the rest of the emissions. This method could possibly be one of the cheaper ways of removing CO2 from power plant emissions and capturing this harmful compound.

This method does not require the building of a new facility for treatment of the gases. The emissions produced by the power plant can be processed on site and do not have to be transferred to a new cleaning facility. This can cut down on costs involved in building an off-site filtering and cleaning facility and can therefore be more cost effective than other techniques.

This technique can also separate other contaminants of the emissions being produced as well. Contaminants such as SO2, NO4, and mercury can be condensed out of the emissions during the process of condensing the CO2. The cooling of the CO2 can also be used to cool the new emissions as they pass through the processing chamber.

This can save on energy costs because the energy from CO2 capture can be harvested and used to continue the process of removing CO2 and other contaminants from the plant's emissions. Because of the multi-faceted benefits of this process, such as removing more than one pollutant and self-cooling mechanisms, this is one of the more promising sustainable solutions to pollutant removal from power plant emissions.

  1. This is a really good idea. I see that it is "patent pending" but is this being used now? Does it look like it will be continued in the future?

  2. Some potential questions are what the energy cost of capture is, and where the captured CO2 is stored (sequestered). Carbon sequestration may have to be part of our immediate solution to reducing emissions as carbon neutral energy sources mature.

  3. The college accepted and renamed the college to Rowan University in appreciation. The renaming was not a condition of the donation. buy weed seeds online
