CO, VOCs & Odor Control

Catalytic Oxidizer (Pro-CatOx System)

A catalyst turns VOCs, CO and odor into CO₂ and water vapour at 200–400°C, rather than the 800°C a thermal incinerator can need. Same destruction, far less heat.

Pro-CatOx is an advanced air pollution control system that removes volatile organic compounds (VOCs), carbon monoxide (CO), and bad odors. It uses a catalyst to turn these pollutants into CO₂ and water vapor (H₂O) at much lower temperatures.

Unlike thermal incineration systems that may need temperatures up to 800°C, Pro-CatOx works at only 200–400°C. The catalyst helps the reaction happen more easily, so pollutants can be destroyed fully without extreme heat.

Principle of the Pro-CatOx

Catalytic reactor: CO and VOCs in, CO2 and water out — 2CO + O₂ → 2CO₂
VOCs + O₂ → H₂O + 2CO₂
2H₂ + O₂ → 2H₂O
CO + H₂O → CO₂ + H₂
VOCs + H₂O → CO + CO₂ + H₂

CO conversion against temperature — High Efficiency CO Destruction at Low Temperature

When waste gases containing CO and VOCs at a temperature of 220°C enter the Pro-CatOx system and come into contact with the Catalyst Surface, a Catalytic Oxidation reaction is triggered. This process effectively acts to break down the chemical bonds of the pollutants, causing them to react with oxygen. Consequently, the toxic molecular structures are completely transformed into clean air, achieving a high efficiency of up to 99%.

How It Works

Heat exchanger, firing heater and catalytic reactor process flow — Process Flow of Pro-CatOx

Waste gas is drawn through a Heater to raise the temperature from ambient 30°C to the operating set point of 350°C.
At the target temp, gas enters the Catalyst Reactor, reacting with the catalyst to completely convert toxic gases into Clean Air.
This chemical reaction releases heat (Exothermic), causing the temperature of the treated clean air to rise significantly.
This high-temp clean air passes through a Heat Exchanger to recover thermal energy for reuse before being discharged outside.
Recovered heat from step 4 preheats incoming gas, reducing the heater's load and enabling Energy Savings of up to 50-60%.
