A new multi-stage circulation (MSC) process for integrating capture of CO 2 and SO 2 using ammonia-based absorbents was proposed.
Aqueous ammonia (NH3)-based capture process has the potential to simultaneously remove NOx/SO2/CO2 pollutants at low cost, but conventional NH3-based
In the present work, the aqueous ammonia-based post-combustion CO2 capture (PCC) process is simulated using the rate-based model in Aspen Plus,
Developing an economic and efficient method to capture carbon diox- ide is an important objective for successful deployment of effective CCS
Post-combustion capture of carbon dioxide is one of the measures to reduce emissions of carbon dioxide from large point source emitters.
Ammonia-based carbon capture is an emerging technology using a chilled ammonia process to remove CO 2 from flue gas.
Rubina aDepartment of Engineering and Public Policy, Carnegie Mellon University, 5000 Forbes Ave. Pittsburgh, 15213, USA Elsevier use only: Received date here; revised date here; accepted date here Abstract The performance and cost of two ammonia-based post-combustion CO2 capture systems operating at a new supercritical coal-fired power plant were modeled and compared to an amine-based CO2 capture system operating at a similar plant. For comparing performance and costs between post-combustion CO2 capture with ammonia and amine technologies, this paper uses the plant derating of CO2 capture on the power plant and the levelized revenue required as two key parameters, as calculated in equation 1 and equation 2.
