CCS with the Alstom chilled ammonia process development program–Field pilot results

Experimental measurement and modeling of the rate of absorption of carbon dioxide by aqueous ammonia

“…The most prominent is the Chilled Ammonia Process (Gal, 2006) being developed by Alstom (Telikapelli et al, 2010) where carbon dioxide is absorbed at low temperature (0-10 • C, 273-283 K). It allows for precipitation of ammonium carbonate compounds and thereby high carbon dioxide loadings in the slurry.…”

Efficiency improvements for the coal-fired power plant retrofit with CO 2 capture plant using chilled ammonia process

“…Development of NH 3 -based PCC processes has reached the pilot plant stage in a relatively short period of time and it was projected that these processes would become commercially available by 2015 [25]. Different options for the NH 3 -based PCC plant have been tested at the pilot-plant scale -the aqueous ammonia process (AAP) at Munmorah pilot plant [26] and the chilled ammonia process (CAP) at Pleasant Prairie and Mountaineer CFPPs -but the CAP campaigns were cancelled due to cost and schedule overruns [27,28].…”

Aqueous Ammonia (NH3) Based Post Combustion CO2Capture: A Review

“…In this process as described in the open literature (Darde et al, 2009;Telikapalli et al, 2011), CO 2 is absorbed in a highly ammoniated solution at low temperatures (0-10°C), producing a slurry containing ammonium bicarbonate. In the stripper, ammonium bicarbonate is converted to ammonium carbonate at temperatures above 100°C and pressures of 20-40 bar.…”

“…Alstom, Powerspan, CSIRO and KIST (Korean Research Institute of Industrial Science & Technology) are the major players in this area and have tested the technologies at pilot-plant scale (McLarnon and Duncan, 2009;Rhee et al, 2011;Telikapalli et al, 2011;Yu et al, 2011a).…”
