Current widespread methods of carbon capture, such as amine treating, use liquid solutions for the treatment of emissions from chemical plants and refineries.
Nearly all commercially - available efforts at scrubbing greenhouse gasses, GHG's, from emissions use a liquid solution of water and amine, derived from ammonia, that contacts the stream, removing CO2 or other unwanted gases.
There's a new CO2 capture technology based on absorption into chilled ammonia / ammonium bicarbonate solution that's supposed to be half as expensive per unit of captured CO2 as current amine absorption technology.
«With our technique, large CO2 separation capacities can be achieved with small temperature swings and regeneration energies that are appreciably lower than what can be achieved with state - of - the - art aqueous amine solutions,» Long says.
In a CO2 collecting tower an amine solution would be pumped up to the top of the tower and allowed to fall from the top to be collected at the bottom.
As the rising air stream passes over the falling amine stream, CO2 is absorbed from the air by the solution which is then collected at the bottom, heated to release the CO2 and then pumped up to the top of tower again.
