1. What is a Fiberglass Scrubber Tower?  
A Fiberglass Scrubber Tower is a vertical structure constructed from fiberglass-reinforced plastic (FRP), used to neutralize and remove contaminants from industrial gas streams. It operates by bringing exhaust gases into contact with a scrubbing liquid (often water or chemical solutions), facilitating the absorption or chemical reaction of pollutants.  

Key Features:  
- Material: Fiberglass offers high resistance to corrosion, UV radiation, and extreme temperatures.  
- Design: Modular or custom-built configurations to suit specific industrial needs.  
- Efficiency: Capable of removing particulates, acidic gases (e.g., SO₂, HCl), and volatile organic compounds (VOCs).

2. Working Principle of Fiberglass Scrubber Towers  
The scrubbing process involves multiple stages:  

1. Gas Inlet: Polluted gas enters the tower through an inlet duct.  
2. Liquid Spray: Scrubbing liquid is sprayed via nozzles, creating a large surface area for gas-liquid contact.  
3. Pollutant Removal: Contaminants dissolve or react with the liquid (e.g., acidic gases neutralized by alkaline solutions).  
4. Mist Elimination: A demister section removes liquid droplets from the cleaned gas before discharge.  
5. Waste Disposal: Contaminated liquid is treated or recycled.  

Types of Scrubbers:  
- Wet Scrubbers: Use liquid to capture pollutants.  
- Dry Scrubbers: Employ dry reagents (e.g., lime) for gas treatment.

3. Advantages of Fiberglass Scrubber Towers  
1. Corrosion Resistance: Superior to steel in acidic or alkaline environments.  
2. Lightweight: Easier to transport and install compared to metal alternatives.  
3. Durability: Long service life with minimal maintenance.  
4. Cost-Effective: Lower lifecycle costs due to reduced repair needs.  
5. Customizability: Adaptable to various flow rates and pollutant types.

4. Applications of Fiberglass Scrubber Towers  
- Chemical Industry: Controls emissions from reactors, storage tanks, and vents.  
- Power Plants: Removes sulfur dioxide (SO₂) from flue gases.  
- Waste Incineration: Neutralizes acidic gases like HCl and HF.  
- Semiconductor Manufacturing: Manages toxic gases (e.g., ammonia, silane).

5. Design Considerations  
- Tower Height: Determines contact time between gas and liquid.  
- Packing Material: Enhances gas-liquid interaction (e.g., random or structured packing).  
- Liquid-to-Gas Ratio: Optimizes pollutant removal efficiency.  
- Pressure Drop: Must be minimized to reduce energy consumption.

6. Installation and Maintenance  
Installation Steps:  
1. Site preparation and foundation setup.  
2. Assembly of FRP sections (bolted or welded).  
3. Integration with pumps, nozzles, and ductwork.  

Maintenance Tips:  
- Regularly inspect nozzles and packing for clogging.  
- Monitor pH levels of scrubbing liquid.  
- Clean demister pads to prevent pressure buildup.
