Pulverized coal (PC) power plants emit CO2 in flue gas at atmospheric pressure with a volume concentration of 10-15%. Post-combustion capture of CO2 is a challenging application but has the greatest near-term potential , because it can be retrofitted to existing state-of-the-art power plants....Read more
