Estimated emissions to the atmosphere from amine based PCC processes for a black coal fired power station based on literature and modelling
Published:31 May 2012
Chemical solvents using amines are the most likely technologies to be deployed in the near future to capture CO2 from industrial flue gases. These solvents have excellent effectiveness and efficiency to absorb CO2 in the flue gas from fossil fuel power plants operating with low partial pressures. In addition, these solvents can be regenerated and injected back into the process to capture more CO2. However, their degradation products may produce new pollutants which could be emitted to the atmosphere.
This case study analyses the latest information available in the public domain and employs the Aspen-Plus process simulator to estimate the atmospheric emissions of degradation products from an aqueous MEA solvent.
