Abstract
Provided are systems and methods for obtaining nitrogen and carbon dioxide gases from a flue gas. A method according to some embodiments comprises receiving a flue gas at an inlet of a selective catalytic reduction system, wherein the flue gas comprises one or more NOx gases; reducing the one or more NOx gases to N2 gas in the selective catalytic reduction system; receiving an output gas from the selective catalytic reduction system at an inlet of a gas separation membrane; and separating the output gas into a retentate and a permeate using the gas separation membrane, wherein the retentate comprises N2 gas.
Claims20
A method for obtaining nitrogen gas from a flue gas, comprising:
- receiving a flue gas at an inlet of a selective catalytic reduction system, wherein the flue gas comprises one or more NOx gases;
- reducing the one or more NOx gases to N2 gas in the selective catalytic reduction system;
- receiving an output gas from the selective catalytic reduction system at an inlet of a gas separation membrane;
- and
- separating the output gas into a retentate and a permeate using the gas separation membrane, wherein the retentate comprises N2 gas.
A system for obtaining nitrogen gas from a flue gas, comprising:
- a selective catalytic reduction system configured to:
- receive a flue gas at an inlet of the selective catalytic reduction system, wherein the flue gas comprises one or more NOx gases;
- and
- reduce the one or more NOx gases to N2 gas;
- and
- a gas separation membrane configured to:
- receive an output gas from the selective catalytic reduction system at an inlet of the gas separation membrane;
- and
- separate the output gas into a retentate and a permeate, wherein the retentate comprises N2 gas.
