Material Construction
The CO system is constructed from AISI 304/316 stainless steel, ensuring exceptional corrosion resistance and durability in harsh environments. This guarantees that the system delivers reliable performance and a long service life, even under demanding operating conditions.
Advantages of CO System
High Destruction Efficiency:
Typically achieves VOC and HAP removal rates of up to 99%. Catalytic oxidation solutions enable effective emission reductions with lower energy consumption.
01
Energy Efficiency:
Fuel requirements can be reduced by up to 50% compared to regenerative thermal oxidizers (RTOs). Electric catalytic oxidizers rely on electricity rather than gas heating, further minimizing secondary emissions like nitrogen oxides (NOx) and aligning with the nation's clean air initiatives.
02
Cost-Effectiveness:
Thanks to reduced fuel consumption and the durability of its catalysts, this technology significantly lowers operating and maintenance costs. Furthermore, the system is capable of adapting to variable airflow rates and a wide range of volatile organic compounds (VOCs).
03
Safety and Environmental Protection:
Featuring an explosion-proof design and generating extremely low levels of secondary pollutants, this technology strongly supports sustainable development practices. These systems ensure continuous and stable pollutant emission reductions.
04

Application of CO System
Paper Manufacturing
Paper mills can treat odors from reductive sulfides and volatile organic compounds (VOCs) in exhaust gases, achieving emission reduction rates exceeding 90%.
Cement Production
Cement plants utilize catalytic oxidation technology to control VOCs generated during kiln operations, significantly lowering pollutant concentrations.
Edible Oil Processing
Food processing plants utilize catalytic oxidation units for deodorization of refining emissions, effectively eliminating organic odors to meet health and safety standards.
Aquatic Fertilizer Production
Fertilizer plants implement specialized treatment for volatile organic compounds and sulfides generated during fish waste processing, significantly improving air quality.
Petroleum Refining
Refineries employ catalytic wet air oxidation to treat wastewater, decomposing organic pollutants and minimizing environmental emissions.
Mining Applications
Used to reduce methane emissions from mine ventilation shafts. This system oxidizes low-concentration methane, aiding in meeting emission targets and enhancing operational safety.
Main components of a Catalytic Oxidizer
Ductwork and Process Fan:
Catalytic oxidation units typically employ a forced-draft system rather than an induced-draft system.
Burner Firing Chamber:
The firing box houses the burner.
Burner, Gas Train, Combustion Blower:
The heat-generating system of the catalytic oxidizer is comprised of the burner, gas train, and combustion blower.
Catalyst Media:
After the air passes through the burner firing chamber, it reaches the catalyst media - typically a monolith or pellet type design.
Primary Heat Exchanger:
In a recuperative or regenerative catalytic oxidizer design, there is a heat exchanger to use the hot, clean air exiting the combustion chamber to pre-heat the incoming dirty air.
Exhaust Stack:
After passing through the heat exchanger, the clean air is exhausted to atmosphere via a stack.
Usage Requirements
Proper Installation:
The CO system must be installed by qualified personnel in accordance with the manufacturer's guidelines and local safety regulations.
Power Stability:
Ensure that the system has a stable and uninterrupted power supply to maintain continuous monitoring functionality.
Regular Calibration:
Sensors must be calibrated periodically to ensure the accuracy of CO detection results.
Alarm Functionality:
The system's alarm signals must be tested regularly to verify that they provide both audible and visual alerts under all operating conditions.
