Process For Removing So.sub.2 And No.sub.x From Gases
Process For Removing So.sub.2 And No.sub.x From Gases
US Patent:
4130628, Dec 19, 1978
Filed:
Aug 22, 1977
Appl. No.:
5/826962
Inventors:
Hubert L. Barnes - State College PA
Edward Shapiro - Pittsburgh PA
Edward Shapiro - Pittsburgh PA
Assignee:
Pittsburgh Environmental and Energy Systems, Inc. - Pittsburgh PA
International Classification:
C01B 2100
US Classification:
423235
Abstract:
A method is disclosed for scrubbing SO. sub. 2 and NO. sub. x containing gases with iron sulfide. The reaction proceeds only to the formation of FeS. sub. 2 and FeSO. sub. 4 without significant formation of sulfur or iron oxide. The reaction products are subsequently regenerated to FeS by heating and can be recycled for further scrubbing operations; elemental sulfur is recovered as a by-product.

Process For Removing So.sub.2 And No.sub.x From Gases
US Patent:
4444736, Apr 24, 1984
Filed:
Jun 28, 1982
Appl. No.:
6/392546
Inventors:
Edward Shapiro - Pittsburgh PA
Assignee:
Pittsburgh Environmental Systems Incorporated - Pittsburgh PA
International Classification:
C01B 2100, C01B 1700
US Classification:
423235
Abstract:
A process for removing SO. sub. 2 and NO. sub. x from waste gas and recovering sulfur comprising scrubbing the waste gases with a water slurry of FeS in the presence of FeSO. sub. 4 and Na. sub. 2 SO. sub. 4. SO. sub. 2 is captured by the formation of FeS. sub. 2 and FeSO. sub. 4 in the scrubber. By thermal regeneration in a reducing atmosphere the FeS. sub. 2 is converted to FeS and Na. sub. 2 SO. sub. 4 to Na. sub. 2 S. The FeS is recycled to the scrubber. The Na. sub. 2 S is returned to the system reacting with FeSO. sub. 4 to form Na. sub. 2 SO. sub. 4 and FeS. The last reaction reduces the amount of FeSO. sub. 4 entering the regenerator where by an undesirable side reaction, it may be partially converted to SO. sub. 2 and Fe. sub. 3 O. sub. 4.
Method For Purification Of Exhaust Gases
Method For Purification Of Exhaust Gases
US Patent:
4041128, Aug 9, 1977
Filed:
Aug 18, 1975
Appl. No.:
5/605558
Inventors:
Henry C. Bramer - Venetia PA
Edward Shapiro - Pittsburgh PA
Edward Shapiro - Pittsburgh PA
Assignee:
Pittsburgh Environmental and Energy Systems, Inc. - Pleasant Hills PA
International Classification:
B01D 5334
US Classification:
4232132
Abstract:
A process and apparatus are provided whereby sulfur and nitrogen oxides as well as carbon monoxides and unburned hydrocarbons are removed from internal combustion engine exhaust gases. The gases are passed through a chamber containing a sulfide and an oxide of iron, copper or zinc. The system is partially self-regenerating and can be used in conjunction with present catalytic converter units or in lieu thereof. In certain embodiments the present invention can also replace muffler units in exhaust systems.
