Overview
In the challenging environment of sulfuric acid plants, it is essential to effectively remove acid mist and droplets from gas streams that exit drying and absorption towers. This is crucial for maintaining optimal operational performance and ensuring environmental compliance. The Advanced Fiber Bed Mist Eliminator is specifically designed to meet these challenges, offering a reliable solution for capturing, collecting, and removing acid mist and droplets.
Key Benefits
1. Acid mist can cause significant corrosion and damage to downstream equipment, leading to increased maintenance costs and downtime. This fiber bed mist eliminator effectively reduces this risk, thereby extending the lifespan of downstream equipment.
2. The fiber bed mist eliminator effectively captures acid mist, helping facilities meet environmental regulations and reducing the impact of off-gas stack emissions on the atmosphere.
3. The mist eliminator enables the recovery of valuable acids from gas streams, improving overall process efficiency and cost-effectiveness.
Mechanisms of Mist Formation
Acid mist and droplets can form through three primary mechanisms:
– Mechanical Formation: Droplets ranging from 10 to 100 microns are typically created when acid is re-entrained due to high-velocity gas flows, tearing droplets from liquid films, or resulting from splashing at liquid distribution devices.
– Condensation: Sudden cooling of hot gases containing sulfur trioxide leads to the formation of finer mist or fumes, generally measuring 3 microns or less.
– Chemical Reaction: A reaction between sulfur trioxide and water can produce mist, especially at the inlet of absorber towers.
Superior Construction and Design
This Advanced Fiber Bed Mist Eliminator features a specially engineered integrated filter fiber felt, known for its high fiber strength and minimal deformation under gas flow. This design ensures a long service life and consistent performance, minimizing the need for frequent replacements.
The mist eliminator’s robust inner and outer framework is constructed as a single unit, preventing short-circuiting and ensuring optimal mist capture. The entire element is rolled to guarantee uniform fiber filling density, enhancing its efficiency in mist collection.
Unique Performance Features
The unique anti-sinking structure of this fiber bed mist eliminator ensures smooth gas flow, avoiding short-circuiting. The fiber bed is designed with a stepwise distribution of fiber diameter, density, and porosity, allowing for high mist removal efficiency while maintaining low bed pressure. This design facilitates the timely drainage of accumulated mist liquids, preventing secondary entrainment of acid mist.
Field measurements have demonstrated the exceptional performance of this fiber fiber bed mist eliminator. With mist particle sizes of 3 microns or larger, the removal efficiency exceeds 99%. For particles 1 micron or smaller, the efficiency remains above 95%, with a pressure drop of less than 2400 Pa.
Proven Success in the sulfuric acid plant
This Advanced Fiber Bed Mist Eliminator has been successfully implemented in lots of sulfuric acid plants. Notably, it was used in the sulfuric acid plant with a capacity of 300 kt/a in a phosphate fertilizer plant at Sinochem. Following this success, it replaced the imported fiber mist eliminator in another absorption tower, achieving excellent performance metrics.
Furthermore, it has effectively replaced imported products in sulfuric acid units at Zhejiang Juhua and Shandong Haohua, proving that it matches or exceeds international standards.
