Industrial Scrubber Systems | High-Efficiency Air Pollution Control
Epcon Industrial Systems designs and manufactures high-performance scrubber systems to effectively remove harmful gases, volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and particulate matter from industrial exhaust streams. Our custom-engineered scrubbers provide reliable pollution abatement while handling high process volumes, fluctuating pressures, and varying contaminant concentrations.
Scrubber systems are often integrated with Regenerative Thermal Oxidizers (RTOs) and other thermal oxidation technologies to provide comprehensive air pollution control, ensuring compliance with strict environmental regulations. In many applications, scrubbers are installed upstream of an RTO, frequently paired with a quench system to reduce process temperatures and neutralize contaminants before oxidation.
Types of Scrubber Technologies
Epcon engineers customized scrubber solutions based on process requirements and exhaust stream characteristics. The selection of scrubber type and neutralizing agents is critical for achieving maximum pollutant removal efficiency.
Wet Scrubbers
Wet scrubbers are among the most widely used air pollution control systems. These systems function by:
- Directing the exhaust stream through the bottom of a packed tower
- Spraying a neutralizing solution counter-current to the exhaust flow
- Capturing and dissolving contaminants within the liquid medium
This process is highly effective for removing acidic gases, chemical pollutants, and particulates, making it ideal for industrial manufacturing, chemical processing, and hazardous waste treatment applications.
Venturi Scrubbers
A Venturi Scrubber is a specialized type of wet scrubber that uses venturi technology to remove particulate matter and gaseous contaminants. By accelerating the exhaust stream through a narrow venturi throat, liquid droplets capture fine particulates, resulting in high-efficiency contaminant removal.
Venturi scrubbers are especially useful in applications requiring fine particulate removal and high gas-phase contaminant scrubbing, such as in chemical processing plants and combustion exhaust treatment.
Dry Scrubbers
Unlike wet scrubbers, dry scrubbers operate by:
- Injecting specialized chemical agents into the exhaust stream at high velocity
- Reacting with or absorbing contaminants in the gas phase
- Neutralizing pollutants before release into the atmosphere
Dry scrubbers are particularly effective for applications where water usage must be minimized, and they are commonly used in power generation, petrochemical refining, and metal processing.
Ammonia Scrubbers
Epcon also engineers ammonia scrubber systems for specialized applications requiring ammonia removal. These systems operate similarly to wet scrubbers, where the ammonia-laden exhaust passes through a packed tower and is sprayed with a neutralizing solution.
Custom Engineering and Expert Process Analysis
Selecting the appropriate scrubber technology requires in-depth process stream analysis to determine:
- The composition and concentration of pollutants
- Optimal neutralizing agents for effective contaminant removal
- Process conditions, including temperature, pressure, and flow rates
With decades of experience in air pollution control systems, Epcon has successfully designed and installed scrubber systems integrated with thermal oxidizers across various industries. Our team of engineers works closely with clients to develop customized solutions that ensure regulatory compliance, energy efficiency, and long-term operational reliability.
