Denitrification towers are essential in steel manufacturing, waste incineration, power plants, fertilizer production, chemical synthesis, and other industries where NO and NO₂ gases are generated. These towers play a vital role in achieving environmental compliance with national and international NOₓ emission regulations, including EPA, EU standards, และ local air quality management laws.

Depending on the process, denitrification towers may operate through wet scrubbing, selective catalytic reduction (SCR), หรือ selective non-catalytic reduction (SNCR) mechanisms. FRP is particularly suited to wet scrubbing applications where acidic or oxidizing solutions such as H₂O₂, NaOH, หรือ KMnO₄ are used to neutralize NOₓ.

Key Features

• ความต้านทานการกัดกร่อน: Handles oxidizing, acidic, and alkaline environments with superior durability.

• High Removal Efficiency: Up to 95–98% NOₓ removal with optimized reagent dosing and tower design.

• Custom Engineered: Designed per emission load, gas flow rate, and temperature for optimal treatment.

• การก่อสร้างที่มีน้ำหนักเบา: Easier handling and reduced installation cost vs. metal alternatives.

• Long Service Life: FRP life expectancy ranges from 15 to 25 years with minimal maintenance.

Working Principle (Wet Scrubbing)

1. Exhaust gas enters the lower inlet of the tower.

2. Liquid oxidizing agent (e.g., NaClO₂, H₂O₂, or KMnO₄) is sprayed downward through spray nozzles.

3. The NO and NO₂ are absorbed and oxidized into HNO₃ or NO₃⁻ compounds in the packing section.

4. Cleaned gas passes through the mist eliminator and exits through the exhaust stack.

5. Absorbent liquid is recirculated via a chemical-resistant pump.
