Treatment of Flue Gas in a CO2 Capture Pilot Plant for a Commercial CFB Boiler

The problem of reducing carbon dioxide emissions from flue gas, particularly gas originating coal-firing CFB systems, is currently an important challenge. Many centers around the world have tested post-combustion CO2 capture systems. One these operated using DR-VPSA adsorption technology (dual-reflux vacuum pressure swing adsorption), was under Strategic Project in Poland. this study originated a supercritical boiler (460 MWe). An involved capturing occurrence SO2 and NOx. These substances negative effect on process. In study, commercial impregnated activated used to remove NOx pre-treatment section during tests pilot unit large-scale at Lagisza Power Plant (Poland). spent analyzed several different methods (N2 adsorption–desorption isotherms, SEM-EDX, XRD, FTIR, TG) evaluate efficiency operation life span adsorbent removal unit. results demonstrate that ensures sufficient purification sulfur oxides but remains insufficient for nitrogen oxides.
