Estimated emissions to the atmosphere from amine based PCC processes for a black coal fired power station based on literature and modelling

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.
