Abstract
A chilled ammonia capture system for capturing carbon dioxide from a flue gas stream comprises a first absorber and a second absorber. The first absorber operates at a temperature of about 25 to about 50 degrees Celsius. The operating temperature permits the use of a lower circulation rate, which leads to smaller diameter vessels and to fewer recirculation pumps, which in turn leads to lower operating and maintenance costs.
