Industrial air pollution is a major concern across multiple sectors, especially those dealing with corrosive gases and chemical emissions. One of the most effective solutions for gas scrubbing and air purification is the use of PP FRP scrubbers. These systems combine chemical resistance and structural integrity, making them ideal for long-term, reliable service in harsh industrial environments.
PP FRP scrubbers are air pollution control systems made using a combination of Polypropylene (PP) as the inner layer and Fiberglass Reinforced Plastic (FRP) as the outer structural layer. These scrubbers work on the principle of wet scrubbing, where harmful gases are absorbed by a scrubbing liquid.
The combination of PP’s chemical resistance and FRP’s mechanical strength offers a superior solution for environments where both durability and corrosion resistance are crucial.
PP FRP scrubbers are available in various configurations, depending on the type of pollutants and industrial process needs:
Ideal for removing acidic gases like HCl and SO2. These use structured or random packing materials to increase contact area between the gas and scrubbing liquid.
Efficient for removing fine particulates and mist. They create a high-velocity gas stream to atomize the liquid, enhancing scrubbing efficiency.
Simple in design, they use spray nozzles to introduce scrubbing liquid into the gas stream. Best suited for moderate volumes and simpler applications.
Combine features of both packed bed and venturi scrubbers. Used for complex emissions containing a mix of gases and particulates.
Designing a PP FRP scrubber requires careful consideration of process and environmental factors:
Packing Type and Surface Area: Crucial for scrubbing performance in packed bed systems.
Below are standard specifications typically observed in PP FRP scrubbers:
Specification | Typical Range |
Diameter | 300 mm to 3000 mm |
Capacity | 500 CFM to 100,000+ CFM |
Construction Materials | Inner: PP, Outer: FRP (ISO/NPG resin) |
Max Operating Temperature | Up to 70°C (customizable) |
Pressure Drop | 50 to 200 mm WC |
Removal Efficiency | Up to 99.9% (application dependent) |
Packing Media | PP Pall Rings, Raschig Rings, etc. |
Scrubbing Solution | NaOH, H2O2, Water, based on application |
Optional Features | Auto pH dosing system, demisters, etc. |
Chemical Manufacturing Units: These industries release corrosive gases like HCl, Cl2, and SO2 during synthesis, which are effectively neutralized using PP FRP scrubbers.
Acid Pickling Lines: Used in metal finishing processes, these lines emit acidic fumes such as hydrochloric or sulfuric acid vapors that need safe scrubbing.
Fertilizer Production Plants: Ammonia and other reactive gases produced during fertilizer formulation are safely controlled through wet scrubbing.
Pharmaceutical Facilities: Complex chemical reactions and solvent usage produce hazardous fumes that require high-efficiency gas scrubbing.
Wastewater Treatment Plants: Odors and chemical gases like H2S and NH3 generated during treatment processes are effectively managed using scrubbers.
Food Processing Industries: Some processes emit pungent or corrosive gases that must be controlled for environmental and worker safety.
Laboratories and R&D Centers: These settings often deal with volatile chemicals that produce fumes needing safe and efficient extraction and scrubbing.
These scrubbers are specifically engineered to handle corrosive gas streams that could deteriorate traditional metallic scrubbers, making them ideal for various industries.
PP FRP scrubbers offer a high-performance, corrosion-resistant, and cost-effective solution for industrial gas cleaning and pollution control. Whether you’re dealing with acidic fumes, alkaline gases, or complex emissions, these systems provide customizable, durable performance that meets stringent environmental compliance standards. Investing in a well-designed scrubber ensures not only regulatory compliance but also enhances the longevity of your facility and protects worker health.
