VOC Scrubbers

VOC Scrubbers are engineered to remove volatile organic compounds from industrial exhaust streams using liquid or wet scrubbing methods. These systems are ideal for processes with high particulate content, moisture-laden exhaust, or low-to-medium VOC concentrations, providing environmentally compliant emission control.

What Are VOC Scrubbers?

VOC Scrubbers use liquid media, typically water or chemical solutions, to capture and neutralize volatile organic compounds from industrial exhaust gases. Gas streams pass through packed beds, trays, or venturi systems where contaminants are absorbed or reacted in the liquid phase.

Scrubbers are effective for wet or particulate-laden exhaust where thermal oxidizers may not be optimal.

System Design & Working Principle

• Exhaust gas enters the scrubber chamber
• Gas contacts liquid medium in packed beds, spray nozzles, or venturi sections
• VOCs dissolve or chemically react with scrubbing solution
• Clean gas exits via mist eliminators or demisters
• Liquid media is recirculated or treated for disposal

Design focuses on mass transfer efficiency, liquid flow distribution, and pressure drop control for stable operation.

Key Specifications & Parameters

• Airflow capacity: from 1,000 to 50,000 Nm³/h (customized)
• VOC concentration range: low to medium
• VOC removal efficiency: 85%–99% depending on design and liquid media
• Operating pressure drop: low to moderate, adjustable
• Liquid recirculation rate: optimized per process

Configurations & Options

• Packed bed scrubbers (counterflow / crossflow)
• Venturi scrubbers for high particulate streams
• Tray-type wet scrubbers
• Recirculation pumps and liquid treatment units
• Acid/base or chemical dosing for specific VOC neutralization

Applicable Industries & Applications

• Chemical and petrochemical manufacturing
• Printing and solvent-based processes
• Surface coating, painting, and finishing operations
• Pharmaceutical production with wet exhaust
• Food & beverage processes with odor and VOC control

Environmental Compliance & Standards

VOC Scrubbers are engineered to achieve stable emission removal in compliance with local and international environmental standards. Liquid effluent is managed according to discharge or recycling regulations, ensuring overall process compliance.

Maintenance & Technical Support

• Regular inspection of nozzles, packing, and spray headers
• Monitoring pressure drop and liquid flow
• Periodic chemical dosing adjustment and liquid replacement
• Spare parts support for pumps, valves, and demisters
• Technical guidance for optimal VOC removal and operational reliability
