The Benefits of Using fiber bed mist eliminators

Typically, collection efficiencies of 94 to 99.7 percent on all particles one micron and smaller in diameter are utilized in Brink® mist eliminator systems. Our diffusion bed mist eliminators are designed for a specified pressure drop, usually in the range of two to 20 inches of water column. Since pressure drop is proportional to fiber bed area, the size and cost of a Brink® diffusion fiber bed increases for lower designed pressure drops and higher collection efficiencies. The figure below shows the effect of pressure drop and collection efficiency on the cost of Brink® mist eliminator diffusion fiber beds for a given gas flow.

NOTE:  Collection efficiencies in all Brink® mist eliminator systems are measured on a weight basis by particle size. Brink® systems can be designed to meet varying client needs, with collection efficiencies of 100 percent on all particles larger than one micron in diameter and as high as 99.999+% on all particles less than one micron in diameter.

We select the optimum fiber bed design for your process to minimize total cost. Note that in addition to up-front capital cost, the overall life cycle cost of mist eliminators includes operating pressure drop (energy consumption) and the cost of maintenance. Often it is better to include extra operating margin in the mist eliminators to extend service life rather than trying to find the lowest cost installation.

For minimum overall life cycle cost, it is important when purchasing a fiber bed system to balance collection efficiency, operating pressure drop, and product service life. Brink® mist eliminator application experience in over 300 applications with over installations world-wide will help assure your fiber bed design will provide balanced, state-of-the-art performance for your peace of mind.

In industries such as sulfuric acid plants and chemical reactors, air quality and safety are of paramount importance. The production processes in these facilities often release harmful gases and mists, including acidic components, particulate matter, and other airborne contaminants. Failing to control these emissions can lead to severe environmental damage, regulatory violations, and health hazards for personnel.

Fiber bed candle filters and fiber bed mist eliminators are essential in controlling these emissions. These filters are crucial for maintaining air quality in sulfuric acid plants, fertilizer processing facilities, and other chemical production environments. Kimre, with over 50 years of experience in the industry, leads the development of advanced air cleaning solutions that significantly reduce harmful emissions. Our cutting-edge candle filters and fiber bed mist eliminators have transformed air purification processes in various industrial sectors.

This content delves into the role of fiber bed filters in sulfuric acid plants, the technologies that drive their performance, and why they are indispensable in maintaining operational efficiency, safety, and environmental compliance in chemical reactors and similar facilities.

The Basics of Fiber Bed Candle Filters

Fiber bed candle filters are cylindrical filtration devices designed to capture and remove liquid mist, particulates, and dissolved solids from gas streams. These filters consist of a densely packed bed of fine fibers that trap contaminants. The arrangement of the fibers ensures the removal of even sub-micron particles, achieving air purity levels that meet the strictest regulatory standards.

Unlike conventional filters, fiber bed candle filters utilize multiple layers of filtration, allowing them to effectively capture particles of varying sizes, including microscopic droplets and aerosols. Kimre’s fiber bed filters are renowned for removing over 99.9% of sub-micron particles, making them essential in industries that prioritize air purity.

Key Advantages of Fiber Bed Mist Eliminators in Sulfuric Acid Plants

In sulfuric acid plants, fiber bed mist eliminators are vital for removing mist droplets from gas streams. These droplets often contain sulfuric acid, which can corrode equipment, reduce efficiency, and create hazardous conditions for workers.

The key advantages of fiber bed mist eliminators in sulfuric acid plants include:

• Increased Equipment Lifespan: By capturing harmful acidic droplets, fiber bed filters protect critical equipment from corrosion, resulting in extended equipment life and reduced maintenance costs.
• Operational Efficiency: Clean air is crucial for maintaining smooth plant operations. Fiber bed mist eliminators ensure that downstream processes remain free of contamination, enhancing operational efficiency.
• Regulatory Compliance: Stringent air pollution regulations are common in sulfuric acid production. Fiber bed mist eliminators help facilities meet these regulations by effectively reducing emissions to acceptable levels.
• Worker Safety: By minimizing the presence of sulfuric acid mist, these filters ensure a safer work environment, reducing the risk of toxic exposure for plant personnel.

How Fiber Bed Filters Work: The Science Behind Air Purification

The design of a fiber bed candle filter is simple yet highly effective. The typical filter consists of a cylindrical element filled with fine fibers that form the filtering bed. These fibers are positioned between two screens, and as mist-laden gas flows through the filter, liquid particles and contaminants are trapped by the fibers.

The filtration process relies on two primary mechanisms:

1. Inertial Collection: Larger particles are captured by the fibers through inertia as the gas stream moves through the filter. This process efficiently traps liquid droplets and solid particulates.
2. Brownian Diffusion: Smaller particles, particularly those below 1 micron, are captured through Brownian motion. In this process, gas molecules collide with sub-micron particles, causing them to deviate from their path and be trapped by the fibers.

Once the liquid droplets are captured, they coalesce on the fiber surface and eventually drain from the filter. This dual-action filtration mechanism enables fiber bed candle filters to provide superior performance, especially in industries with complex contamination challenges, such as sulfuric acid plants and fertilizer processing units.

Customization and Versatility of Candle Filters

A key feature of Kimre’s fiber bed filters is their versatility. These filters can be customized to meet the specific requirements of various industries, whether for new installations or retrofitting existing systems. Customization options include adjustments to fiber grades, densities, and sizes to optimize filtration performance based on the unique demands of the facility.

For example, Kimre’s fiber bed candle filters can be configured for both forward flow (gas moving from inside to outside) and reverse flow (gas moving from outside to inside). This flexibility ensures optimal filter performance in diverse industrial applications, allowing companies to achieve their air purity objectives without compromising operational efficiency or safety.

Fiber Bed Mist Eliminators in Fertilizer Processing

Fertilizer production, particularly in phosphate and nitrogenous fertilizer plants, generates substantial quantities of airborne pollutants. Mist eliminators play a vital role in controlling these emissions and ensuring compliance with air quality regulations.

In fertilizer processing, fiber bed mist eliminators offer the following advantages:

• Improved Product Quality: By removing airborne contaminants, mist eliminators prevent impurities from affecting the final product, ensuring higher-quality fertilizers.
• Reduced Emissions: With advanced filtration technologies, fiber bed mist eliminators significantly reduce harmful emissions released during fertilizer production, especially in processes involving ammonium nitrate or nitric acid.
• Cost Savings: By mitigating the damage caused by corrosive particles, mist eliminators reduce equipment maintenance costs and improve overall plant efficiency.
