Abstract:
Carbon dioxide is separated from flue gas by scrubbing the gas with an aqueous solution of ammonia and salt, and the CO 2  is therefore released from the solution by heating. The scrubbing step is performed with a co-current stream of an aqueous solution of ammonia and a salt.

Claim (Index 1):
A system for recovery carbon dioxide from a flue gas containing carbon dioxide comprising the steps of:\n a. burning a fossil fuel to create a supply of flue gas containing carbon dioxide at a fossil site; b. continuously transporting the flue gas supply to the top of an absorption column packed with an aqueous solution of ammonia and a salt chosen from the group consisting of Na Cl and K Cl while replenishing the solution to the top of the column thereby scrubbing the flue gas by a downward co-current flow of the gas and the solution though the column at a temperature of between 15\u00b0 C. and 50\u00b0 C. thereby saturating the solution with carbon dioxide to produce a bicarbonate and ammonia chloride; c. thereafter heating the carbon dioxide enriched solution taken from the bottom of the column to release the absorbed carbon dioxide; and d. recycling the regenerated aqueous solution to the top of the column to replenish the solution for step (b).
