Carbon monoxide (CO) presents a unique challenge for wet scrubbing because it has extremely low solubility in water (≈2.3 mL/100 mL at 20 °C). Unlike HCl or NH₃ which dissolve readily, CO requires chemical absorption rather than physical dissolution.

• Copper-ammonia absorption: CO forms a complex with cuprous ammonium compounds (Cu(NH₃)₂⁺). The CO-loaded solution is regenerated by heating, releasing concentrated CO for recovery or further treatment. This is the most established wet chemical CO removal method.
• Catalytic oxidation: For many industrial exhaust streams, the most practical approach is catalytic oxidation of CO to CO₂ over a precious metal catalyst (Pt/Pd) at 150–300 °C. The CO₂ can then be removed with a standard caustic scrubber if emission limits require it.
• Limited wet-only removal: Standard packed bed or spray tower designs without chemical reagents achieve <10% CO removal. Do not specify a water-only scrubber for CO control without chemical augmentation.

Our carbon monoxide scrubber system is a high-efficiency industrial waste gas treatment equipment, designed to solve the acid mist and toxic gas emission problems in traditional production workshops. As a leading manufacturer with 16 years of experience in environmental protection equipment, we provide custom solutions for UAE and global clients. This scrubber is made of high-quality PP polypropylene sheets and matched with PP PVC pipe fittings, ensuring full corrosion resistance for harsh acid mist environments. It can achieve 95% purification efficiency, helping you meet local emission standards and reduce long-term maintenance cost by 70% compared to traditional steel scrubbers.

How Does The Carbon Monoxide Scrubber System Work?

Step 1: Gas Intake & Pre-treatment

In the initial stage, the acid mist exhaust gas is collected by the suction hood, then flows through the PP air duct into the scrubber. The anti-corrosion centrifugal fan draws the gas into the system, slowing down the gas flow to prepare for the neutralization process, while the PP structure protects the equipment from raw corrosive gas damage.

Step 2: Spray Washing & Neutralization

As the gas flows upward through the packing layer, it fully contacts with the sodium hydroxide alkali solution. The acid-base neutralization reaction takes place here, removing over 90% of the acid mist and toxic gas. The PP structure of the scrubber resists corrosion from the neutralizing solution, maintaining long-term structural integrity.

Step 3: Demisting & Adsorption

After neutralization, the gas passes through the demisting layer to remove water mist carried by the gas flow. The demisting layer ensures no moisture is carried to the next stage, preventing water pollution and ensuring the gas is clean enough for discharge.

Step 4: Clean Gas Discharge

Finally, the fully treated clean gas is sent to the chimney system by the centrifugal fan, and discharged at 15 meters height, meeting all local emission standards. The UV-stabilized PP structure ensures the system can work stably outdoors for over 10 years.

Successful Customer Case

In 2023, we partnered with a large electroplating factory in Dubai, UAE, which was facing serious acid mist emission problems. Their old system failed to meet the local emission standard, leading to failed environmental inspections. We provided them with a custom carbon monoxide scrubber system, matched with their workshop space and waste gas condition. After installation, the factory achieved 95% purification efficiency, passed the environmental inspection on the first try, and reduced their annual maintenance cost by 70%. They have now extended their system’s expected lifespan from 3 years to over 15 years, and have placed 2 repeat orders for other workshops.

Best Fit Applications

Not Recommended / Engineering Limits

• CO as primary pollutant: Wet scrubbing has limited efficiency for CO. A catalytic oxidizer or adsorption system is typically more effective.
• High temperature (>60 °C): Standard PP configuration limited to 60 °C.
• Confirm with engineering: CO removal requires chemical absorption (copper-ammonia or similar). Please provide full gas analysis for a design review.

This carbon monoxide scrubber is designed for:

• Target gas: CO (carbon monoxide) from industrial exhaust streams
• Note: CO has very low water solubility. Catalytic oxidation (CO → CO₂) or chemical absorption with copper-ammonia solution is typically required.
• Airflow: 1,000–20,000 m³/h
• Best industries: Boiler rooms, generator exhaust, underground parking ventilation, steel mills, chemical plants
