Flow Chart of Ammonia Gas Treatment (Catalytic Burning Method)

1)Taking outer air and heating it through heat exchanger.
2)Gases containing Ammonia introduced to box and mixed with heated air.
3)Mixed gas heated up to temperatures of initiation for catalyst reaction.
4)During passing through catalytic layers, Ammonia and Oxygen reacted on catalytic surface to produce Nitrogen and water vapor. (Catalytic Burning Method)
5)Produced dissociation heat of Ammonia heating outer air at heat exchanger.
6)Nitrogen and water, after cooling, exhausted into air.

Performances and Efficiencies of Badly Smelling Gas Deodorization Odor Concentration

Fermentation odor, rotten organics odor and odor containing ammonia should be decomposed more than 99%
Bad odor from fermented composts, human waste, sewage sludge, seafood processing, poultry farming, swine keeping, waste water from farms etc. these odor should be deodorized satisfactory.

*Deodorizing Example : sewage compost

Items	Inlet	Exhaust
Ammonia	150	below 0.1
Methyl Mercaptan	1.3	below 0.0001
Methyl Sulfide	0.85	0.0001
Trimethylamine	2.3	below 0.0005
Nitrogen Oxide	9.4	10.0

unit;ppm(Volume)

*Deodorizing Example : animal excrements disposing

Items	Inlet	Exhaust
Ammonia	14	1.2
Methyl Mercaptan	2.10	0.0049
Methyl Sulfide	53	0.29
Concentration of Odor (Japan standard)	170,000	55
