1. Design and Construction  
The Fiberglass Absorption Tower-4 is engineered for durability and corrosion resistance, leveraging fiberglass-reinforced plastic (FRP) as its primary material. Key design features include:  
- Modular Structure: Facilitates easy installation and scalability.  
- Internal Packing Media: Enhances gas-liquid contact for efficient absorption (e.g., random or structured packing).  
- Spray Nozzles: Uniformly distribute absorbent liquids (e.g., water or chemical solutions).  
- Demister Pads: Prevent liquid carryover in the exhaust stream.  

The tower’s FRP construction ensures longevity in harsh environments, resisting acids, alkalis, and high temperatures (up to 180°C).

2. Working Principle  
The tower operates on the principle of counter-current flow:  
1. Gas Inlet: Polluted gas enters the tower’s base.  
2. Liquid Absorption: Absorbent sprays from the top react with gases (e.g., HCl, SO₂) as they rise.  
3. Chemical Reaction: Pollutants dissolve or react (e.g., SO₂ + NaOH → Na₂SO₃).  
4. Clean Gas Exit: Treated gas exits via the demister, while waste liquid drains for further processing.  

This process achieves >95% pollutant removal efficiency, complying with stringent emission standards.

3. Applications  
The Fiberglass Absorption Tower-4 is widely used in:  
- Chemical Plants: For HCl, Cl₂, or ammonia scrubbing.  
- Power Generation: Flue gas desulfurization (FGD) in coal-fired plants.  
- Waste Incineration: Neutralizing acidic gases (e.g., HF, SO₃).  
- Semiconductor Manufacturing: Controlling toxic fumes (e.g., SiH₄).  

Its adaptability to various absorbents (water, alkaline solutions) makes it versatile across industries.

4. Advantages Over Traditional Towers  
- Corrosion Resistance: FRP outperforms steel or PVC in acidic/alkaline environments.  
- Lightweight: Reduces structural support costs.  
- Low Maintenance: Non-reactive surfaces minimize scaling and fouling.  
- Cost-Effectiveness: Longer lifespan (20+ years) lowers total ownership costs.

5. Performance Optimization  
To maximize efficiency:  
- pH Monitoring: Ensures optimal absorbent reactivity.  
- Flow Rate Control: Balances gas velocity and liquid distribution.  
- Regular Inspections: Prevents packing media clogging.  

Case studies show a 30% efficiency boost with automated pH and flow controls.
