Hello! I am designing an absorption column and stripper to capture CO2 from flue gas from a coal power plant (around 300 MW power production). The solvent to use is 30% wt monoethanolamine.
Given the following conditions:
Flue Gas flowrate: 2517 tons/hr
CO2 flowrate: 450 tons/hr
Flue gas pressure: 1.2 bar
Flue gas temperature: 40 deg C
MEA flowrate: 7551 tons/hr.
What type of column should I use (packed or tray)? The flowrates described above are very large, in this case, should I use multiple absorbers in parallel? Consider also the economics. It would be of great help if you can have comments about this design. Thank you!
