HCl and HF Removal Methods with Ceramic Media: Advanced Acid Gas Control Solutions by ZTW Tech

Revolutionary HCl and HF Removal Methods with Ceramic Media Technology

Industrial operations across multiple sectors face significant challenges in controlling hydrochloric acid (HCl) and hydrofluoric acid (HF) emissions. These acidic gases pose serious environmental and operational concerns, requiring advanced treatment solutions that can withstand harsh industrial conditions while maintaining high removal efficiency.

Technical Fundamentals of Ceramic Media for Acid Gas Removal

ZTW Tech's ceramic media represents a breakthrough in acid gas control technology. The unique nano-porous structure of our ceramic filter tubes provides exceptional surface area for chemical reactions and physical filtration. When implementing HCl and HF removal methods with ceramic media, the system operates through multiple mechanisms including chemisorption, surface reaction, and deep-bed filtration.

The ceramic media's composition includes specialized alkaline components that actively neutralize acidic gases. For HCl removal, the reaction follows: Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O. Similarly, HF removal occurs through: Ca(OH)₂ + 2HF → CaF₂ + 2H₂O. These reactions occur continuously within the porous ceramic structure, ensuring consistent performance.

System Configuration and Operational Advantages

ZTW Tech's integrated systems employ ceramic catalyst filter tubes and high-temperature ceramic fiber filter tubes as core components. The multi-tube bundle system design ensures uniform gas distribution and optimal contact between flue gases and ceramic media. This configuration is particularly effective for HCl and HF removal methods with ceramic media in applications with fluctuating gas compositions and temperatures.

Key operational advantages include:

• Operating temperature range: 180-450°C
• Pressure drop: <1500 Pa
• Filtration efficiency: 99.9% for particulate matter
• Acid gas removal efficiency: 99%+ for HCl and HF
• System availability: >98%
