Abstract
A method for removing ammonia from a gas stream divides the gas steam into a plurality of separate gas streams and sprays a dilute acid solution into the streams. The acid solution is aqueous sulfuric acid and ammonium sulfate is produced. A device is used to divide the gas stream, the device having a plurality of conduits in fluid communication with a plenum. Spray nozzles are located in each conduit to spray the acid solution into the gas streams. The device creates less than 10 Pa back pressure to the gas stream.
Claims18
A device for removing a substance from a gas stream by spraying a liquid into said gas stream, said device comprising:
- at least one conduit, said conduit being substantially unobstructed to permit flow of said gas stream therethrough without significant resistance, said conduit having a first and a second end, said first end of said conduit being in fluid communication with the atmosphere;
- and
- a plurality of spray nozzles positioned in said conduit for spraying said liquid into said gas stream thereby subjecting said entire gas stream to said liquid while passing through said conduit.
A method for removing ammonia from a gas, said method comprising:
- passing said gas through at least one conduit, said conduit being substantially unobstructed to permit flow of said gas stream therethrough without significant resistance, said conduit having a first and a second end;
- and
- spraying said gas as it passes through said conduit with an aqueous acid to generate an ammonium solution, wherein
- said aqueous acid is delivered by a plurality of spray nozzles positioned in said conduit.
