FAQs

The most reliable solutions for air pollution control depend on the specific application and contaminant. Air strippers achieve up to 99.9% removal efficiency, removing volatile organic compounds (VOCs) and dissolved gases from water. Wet scrubber systems are effective at handling hot, corrosive gas streams and capturing dust, which makes them a leading solution for exhaust streams.

MACH Engineering’s custom-engineered solutions are designed for maximum uptime and durability. Our experts help you select the right system for your process and design it to meet your exact requirements.

The best material choice for tower packing and internals depends on factors such as temperature, corrosion resistance and the chemical composition of the gas stream. 

Metal packing materials like stainless steel 304, 316 and 316L are best suited for high-temperature and mechanically demanding applications. They offer exceptional structural strength and good resistance to oxidation.

Ceramic tower packing materials like stoneware, alumina and porcelain are best for highly corrosive environments and high-temperature processes. They are non-reactive, immune to most chemical attacks and can have a thermal stability of up to 1300°C.

Plastic packing materials like polypropylene, polyvinyl chloride, polytetrafluoroethylene and polyvinylidene fluoride are suitable for low-temperature applications, wastewater treatment and air scrubbing systems. They have high corrosion resistance to acids and bases and provide effective liquid distribution.

The best choice will depend on factors like your project’s timeline, budget and operational goals.  Renting offers greater flexibility and lower up-front costs for short-term needs, while purchasing provides long-term cost savings and customization for permanent applications. 

Common issues of air pollution control systems include clogging, fouling of packing material, pump or fan failure, chemical imbalances, and corrosion. We offer designs specialized to mitigate these risks and facilitate easy maintenance through proper material selection and robust components.

The lifespan of wet scrubber systems depends heavily on the materials of construction, the corrosiveness of the environment and the quality of the maintenance program. A general range for well-maintained systems spans from 15 to 25 years. MACH Engineering builds systems with longevity in mind, using high-quality, corrosion-resistant materials.

Wet scrubbers provide significant environmental benefits. They remove harmful pollutants from industrial exhaust streams, preventing them from entering the atmosphere. These machines improve air quality and mitigate acid rain by capturing acid gases like sulfur dioxide (SO₂) and hydrogen chloride (HCl). These capabilities also help companies achieve their corporate sustainability and environmental stewardship goals.
