Anguil Asia’s Catalytic Recuperative Oxidizer(CO) destroys the pollutants in the off-gas by using catalyst. It is one of Anguil Asia’s conventional technologies with the advantage of low operating temperature, saving energy consumption, and high destruction removal efficiency. Catalytic Oxidizer is widely used in the industrial manufacturing such as painting, chemical and petrochemical.
There is no –inside CO, usually there is a heat exchanger to preheat the VOCs laden process gas before it goes into the oxidizer. The preheated gas then enters into the oxidizer and raised to the catalyst operating temperature, an exothermic reaction takes place as the pollutants are converted to CO2 and water vapor. The clean and hot gas flue then passes through the heat exchanger to transfer its thermal energy to preheat the incoming air before it is exhausted into the air through the stack.
By using different catalyst with different oxidization temperature, the inlet temperature usually is lower at 250-305℃. The heat will be released during the oxidization reaction occurred at the catalytic bed and the temperature in the oxidizer will be increased, to 300℃ for example, depending on the VOCs concentration and its heat value. Because of the lower inlet temperature, there is less energy required to maintain the oxidation temperature, this will save the energy consumption accordingly.
1.Low process volume, medium to high emission concentration.
2.Strict limitation on gas or power.
3.VOCs laden process gas with pollutants can be destroyed by the catalysts.
4.Fully characterized process streams with no catalyst poisons, particulates, adhesive substances or masking agents.
1.Alternate fuel and power supplies, including electrically heated.
2.Multiple catalyst options including precious or base metals.
3.Acid gas scrubber or SCR module with a completely integrated control system.
4.Multiple heat exchanger for waste heat recovery and utilization.
