Methods For Controlling N.sub.2 O Emissions And For The Reduction Of No.sub . .Sub.x Emissions In Combustion Systems While Controlling N.sub.2 O Emissions

US Patent:
5270025, Dec 14, 1993
Filed:
Mar 25, 1992
Appl. No.:
7/858316
Inventors:
Loc Ho - Anaheim CA
Shih L. Chen - Irvine CA
William R. Seeker - San Clemente CA
Peter M. Maly - El Toro CA
Assignee:
Energy & Environmental Research Corp. - Irvine CA
International Classification:
C01B 2100
C01B 1700
C01B 1720
B01J 800
US Classification:
423235
Abstract:
Method for controlling N. sub. 2 O emissions from stationary combustion systems having variable flue gas temperatures are disclosed. The N. sub. 2 O emissions are controlled by the introduction of a N. sub. 2 O control agent, such as an alkaline compound, into the effluent stream. In addition, the present invention discloses methods for controlling N. sub. 2 O emissions from stationary combustion systems having variable flue gas temperatures while reducing NO. sub. x emissions. Use of an NO. sub. x reducing agent and an N. sub. 2 O control agent, such as urea and monosodium glutamate, enlarges the temperature window for effective selective noncatalytic NO. sub. x reduction while significantly eliminating N. sub. 2 O emissions commonly experienced with urea injection. Further, the present invention discloses methods for controlling N. sub.

Methods Of Reducing No.sub.x And So.sub.x Emissions From Combustion Systems

US Patent:
4861567, Aug 29, 1989
Filed:
Apr 16, 1987
Appl. No.:
7/039324
Inventors:
Michael P. Heap - Corona Del Mar CA
Shih L. Chen - Irvine CA
James M. McCarthy - Laguna Beach CA
David W. Pershing - Salt Lake City UT
Assignee:
Energy and Environmental Research Corporation - Irvine CA
International Classification:
C01B 2100
C01B 1700
B01J 800
US Classification:
423235
Abstract:
The present invention relates to methods for selectively reducing NO. sub. x so that nitrogen can be removed from emission effluent streams and NO. sub. x emissions can be reduced to very low levels. In addition, the present invention teaches a method whereby NO. sub. x and SO. sub. x may be simultaneously removed from the effluent stream. The present invention teaches the reduction of NO. sub. x with cyanuric acid. Initially, cyanuric acid is decomposed to form decomposition products. The reaction of cyanuric acid to produce its decomposition products, such as isocyanic acid or related reaction intermediates, takes place in an oxygen-free, fuel rich, decomposition zone with the reaction temperature in the range of from about 1000. degree. F. to about 3000. degree. F. After the cyanuric acid is decomposed in the absence of oxygen, the decomposition stream is mixed with the effluent stream containing NO. sub. x.

Methods Of Removing No.sub.x And So.sub.x Emissions From Combustion Systems Using Nitrogenous Compounds

US Patent:
4851201, Jul 25, 1989
Filed:
Jul 15, 1987
Appl. No.:
7/073980
Inventors:
Michael P. Heap - Corona Del Mar CA
Shih L. Chen - Irvine CA
James M. McCarthy - Laguna Beach CA
David W. Pershing - Salt Lake City UT
Assignee:
Energy and Environmental Research Corporation - Irvine CA
International Classification:
C01B 2100
C01B 1700
B01J 800
US Classification:
423235
Abstract:
The present invention relates to methods for selectively reducing NO. sub. x so that nitrogen can be removed from emission effluent streams and NO. sub. x emissions can be reduced to very low levels. In addition, the present invention teaches a method whereby NO. sub. x and SO. sub. x may be simultaneously removed from the effluent stream. The present invention teaches the reduction of NO. sub. x with --NH and --CN containing selective reducing agents such as ammonium sulfate, urea, and NH. sub. 3. Initially, the selective reducing agent is decomposed in a fuel-rich environment to form highly reactive decomposition products. The reaction of the selective reducing agent to produce its decomposition products, such as NH, NH. sub. 2, and related reaction intermediates, takes place in an oxygen-free, fuel-rich decomposition zone with the reaction temperature in the range of from about 300. degree. F. to about 2400. degree. F.
