Plasma Ion Catalytic Deodorizer
- Plasma-Ion Catalitic System
- Based on rich and diverse experiences and performances, EST provides the best solution for bad smells.
Plasma Ion Catalytic Deodorization Facility
Mechanism
- To remove the foul smelling gas discharged from bad smell emitting facilities, the complex technology generates radical hydroxide (OH-, HOO-) that effectively responds to foul smelling gas in low-temperature plasma, produces primary reaction with inflowing gas, and ultimately degenerates in porous catalyst.
Characteristics
- Plasma ion and porous catalyst are used to adsorb/degenerate the foul smelling gas and emit harmless gas (N2, Co2, H2O, etc.).
- Excellent applicability on low-concentration, high-concentration, and all types of foul smelling gas.
- Eco-friendly technology free from generation of secondary pollutant.
- Easy installation and management. Low initial investment cost and operation cost compared to other methods.
Gas Elimination Process
-
Ammonia
Elimination Reaction- 2NH3 + HO∙ + 1.5O2 → N2 + 3H2O + HO-
- 2NH3 + HO2∙ + 1.5O2 → N2 + 3H2O + HOO-
- 2NH3 + O2· + 1.5O2 → N2 + 3H2O +O2
-
Hydrogen Sulfide
Elimination Reaction- 4H2S + HO∙ + 1.5O2 → 2S2(↓) + 4H2O + H+
- 4H2S + HO2∙ + 1.5O2 → 2S2(↓) + 4H2O + HO-
- 4H2S + O2· + 1.5O2 → 2S2(↓) + 4H2O + O-
