SOURCE CAPTURE
CAPTURE - TRANSPORTATION – STORAGE OF CO2
CAPTURE
Source of CO2
NGCC (Natural Gas Combined Cycle) plant
nominal capacity: 468 MW
real capacity: 85% of nominal capacity
emission factor: 450 kg CO2/MWh
concentration of CO2 in flue gas: 4% volume
working hours :8000 h/year
3530 tons of CO2 per day
post-combustion capture
chemical absorption
monoethanolamine (MEA) at 30%
pureness of CO2: ≥ 99%
recovery rate: 90%
CAPTURE
Fluor Daniel Econamine FG process
2R-NH2 + CO2 → R-NH3+ + R-NH-COO-
R=HO-CH2CH2
Absorber:
Stripper: R-NH-COO- + R-NH3+ + (calore) → CO2 + 2R-NH2

Parameters
100% CO2
The pipeline has cooled to 6,2°C, which is the minimum temperature
of the soil at 1m of depth.
Maximum inlet pressure is 2200 psia (152 bar)
The pipe can be stressed to 72% of specified minimum yield strength
Internal corrosion: none
