Impact of impurities from oxy-fuel CO2 streams on compression strategies for carbon capture and sequestration

The efficacy of Carbon Capture and Sequestration (CCS) as a means to mitigate the CO2 gas emissions from industrial sectors, including fossil fuel operated power stations, requires the minimisation of the costs associated with compression and transportation of the captured CO2. CO2 compression share...

description The efficacy of Carbon Capture and Sequestration (CCS) as a means to mitigate the CO2 gas emissions from industrial sectors, including fossil fuel operated power stations, requires the minimisation of the costs associated with compression and transportation of the captured CO2.
