Single Column VSA Studies for CO2 Recovery using Metal Organic Framework Adsorbent: Comparison with Commercial Zeolite

摘要

Rising levels of CO2 in the atmosphere due to burning of fossil fuel have been recognized to be the main contributor of global warming and associated climate change phenomenon. Fossil fuel combustion for power generation is the major source of increased CO2 levels in the atmosphere, but capturing CO2 from flue gas emissions in power plants where it is available as a low pressure stream, presents a formidable challenge. Current technologies available such as amine based absorption processes are considered uneconomic and there is a concerted effort being made to improve such processes or develop more efficient alternative processes. In this context adsorption processes using Pressure or Vacuum Swing Adsorption (PSA/VSA) are attracting interest as energy requirements are lower [1].
