Abstract
A CO2 capture system 200 including a system for removing NO2 from a first gas stream 210 before CO2 capture is disclosed. The CO2 capture system 200 includes a protection bed 220 and a CO2 absorber 260. The protection bed 220 may absorb the NO2 or convert the NO2 to either NO or N2.
Claims20
A CO2 capture system, comprising:
- a protection bed 220 configured to receive a first gas stream 210 and to substantially remove NO2 from the first gas stream to produce a second gas stream 230;
- and
- a CO2 capture unit 260 configured to produce a CO2 rich stream 280 from the second gas stream 230.
A facility, comprising:
- a component generating a first gas stream 210 comprising CO2;
- and
- a CO2 capture system 200 for removing CO2 from the first gas stream 210, the CO2 capture unit 200 comprising:
- a protection bed 220 configured to receive the first gas stream 210 and to substantially remove NO2 from the first gas stream 210 to produce a second gas stream 230;
- and
- a CO2 capture unit 260 configured to produce a CO2 rich gas stream from the second gas stream 230.
3 more elements
A method for removing carbon dioxide from a gas stream 210, comprising:
- providing a first gas stream to a protection bed 220, the protection bed 220 configured to substantially remove NO2 from the gas stream 210 to produce a second gas stream 230;
- providing the second gas stream to a CO2 capture unit 260 to produce a CO2 rich gas stream 280.
The method of 13, further comprising:
- regenerating the protection bed 220 by flowing a reduction gas stream through the protection bed 220.
