초록 ▼

The present invention relates to a process for removing nitrogen oxides from gas streams such as furnace or utility boiler flue gas streams. An adsorber system is used to adsorb nitrogen oxides from the flue gas streams. An oxygen/ozone gas stream contacts the nitrogen oxides to convert the nitrogen

대표청구항 ▼

1. A process for removing nitrogen oxides from a gas stream comprising: feeding said gas stream to a nitrogen oxides adsorber selected from the group consisting of a multi-fixed bed adsorber and a rotary wheel adsorber containing a metal oxide based chemisorbent or an adsorbent selected from the group consisting of Y zeolites, γ-alumina, treated γ-alumina and supported MgO, whereby said nitrogen oxides are adsorbed in said adsorber; and feeding an ozone and oxygen containing gas stream to said adsorber, whereby said ozone reacts with said nitrogen oxides to form N2O5. 2. The process as claimed in claim 1 wherein said rotary wheel adsorber alternates between adsorption and regeneration sections as said rotary wheel rotates. 3. The process as claimed in claim 1 wherein said ozone and oxygen gas stream is provided by an ozone generator. 4. The process as claimed in claim 3 wherein said ozone and oxygen gas stream contains from about 3 to 10% by weight ozone. 5. The process as claimed in claim 3 wherein the oxygen from said adsorber is recycled to the ozone generator. 6. The process as claimed in claim 1 wherein said rotary wheel adsorber comprises at least two sectors. 7. The process as claimed in claim 1 wherein said gas stream passes through said adsorption cycle and said oxygen and ozone gas stream passes through said regeneration cycle. 8. The process as claimed in claim 1 wherein the oxygen and ozone containing stream is heated to a temperature of 50-150° C. before being sent to said adsorber. 9. The process as claimed in claim 1 wherein said N2O5is contained within an oxygen stream and is fed to a wet scrubber system. 10. The process as claimed in claim 9 wherein said wet scrubber system contains a dilute basic aqueous solution. 11. The process as claimed in claim 1 wherein said nitrogen oxides-containing gas stream also contains sulfur oxides. 12. The process as claimed in claim 1 wherein said nitrogen oxides-containing gas stream is a flue gas stream. 13. The process as claimed in claim 12 wherein said flue gas stream is a furnace or utility boiler flue gas stream. 14. The process as claimed in claim 1 wherein said nitrogen oxides-containing gas stream is a chemical processing stream. 15. The process as claimed in claim 14 wherein said chemical processing stream is selected from the group consisting of metal pickling, fluid catalytic cracker and food processing streams.
