How To Keep Your Scrubber Working Properly

 

Scrubbers are groups of different devices that come together to control air contamination through many mediums. A large component of scrubbers are the filters used to remove gases and particulates of different sizes in order to purify industrial exhaust streams. To keep the scrubber working properly, mist eliminator filters are used because they collect and remove dangerous mist that would contaminate the air.

Mist eliminators come in different diameters made to fit the needs of the scrubber/ system. The filter is composed of layers of filters piled on top of one another. The layers are made up of different materials, such as thermoplastic that can withstand high heat while collecting harmful particulates and acidic mists. Each layer can also be comprised of different diameter sizes based on the particle size that needs to be captured. Choosing the right diameter filter for your Scrubber will be the difference between an efficient scrubber and one that releases contaminants. For example, if the diameter of the filter is too large, unwanted particulates can escape and contaminate the air. If the diameter is too small, clogs can form in the system impacting flow. In either case, the result is an inefficient filter that will negatively impact the system as a whole.

When considering how to maintain your system, the type of mist eliminator is also important. Since each system is designed to handle different types of contaminants, the mist eliminator used should match the requirements of the system. For example, when running a system that deals with particles that tend to cause pressure drops within the system, using mist eliminator mesh as it is designed for that purpose will help to combat pressure drops.

Components of a Fiber Bed Filter

Fiber Bed Filters are typically used in the removal of sub-micron particles and liquids in the gas stream through inertial and Brownian diffusion collection mechanisms. Fiber Bed Filters offer a high collection efficiency, up to 99.9% removal can documented. Fiber Bed Filters capture and collect oil mist from the airstream which optimize performance and protect the downstream equipment from failure. They can be used in organic applications, such as, asphalt roofing products, compressed air and gasses, food processing, metal matching oil mist, plasticizer, and rotating equipment lube oil reservoirs. Fiber Bed Filters can also be used in chemical processing applications, such as, sulfuric acid, chlorine and chlor-alkali, pulp and paper, semiconductor, acid storage tanks and platinum recovery. Overall, filters offer high removal efficiency, easy installation, simplified maintenance, and long filter life.

Fiber Bed filters are typically cylindrical and can range is size, reaching heights reaching 20 feet. The filter is composed of various structural materials known as cages or screens. These cages are made of various durable materials such as, stainless steel, carbon steel, corrosion resistant alloys and polymer materials. Sometimes Fiber Bed Filters are constructed with FRP inner and outer cages and plated, this design is often used for controlling fumes from toxic chemicals from waste incineration applications. The “bed” portion of the filter is typically composed of fine fibers of media consisting of various grades and densities packed between two cylindrical screens with flanges at the end. Pressure drop and collection efficiency are influenced by the fiber material, the diameter of the fibers and the density in which it is packed. Fiber bed filters can be either hanging filters or standing filters and typically can by handled by two technicians.

The contaminated airflow either enters from the center of the filter to the outside (forward flow) or from the outside to the inside (reverse flow). Only particles are collected by the filters, any vapors that enter the filter will pass through and be exhausted with the air. That is why the efficiency is given for particle collection. In addition, the Brownian diffusion collection is achieved through the design of a specific bed depth. This “deep bed” filtration makes it more important to limit the amount of insoluble solids that enter the filter. Insoluble solids will collect permanently in the filter, while liquid particulate, such as condensed asphalt light end will coalesce and drain from the filter.

Mesh Pads vs Vane Pads

 Mist eliminators are designed to remove entrained liquid droplets from the gas streams such as oil mist during manufacturing or industrial process. Removal of contaminants will assist with recovery of valuable products, improve emissions, and protect downstream equipment. In this blog, we will discuss the basic similarities of vanes and mist eliminator mesh pads.

Both vane mist eliminators and mesh mist eliminators operate using the same principle of impaction to capture the droplets. As the droplets contact the filaments in a mesh pad or the surfaces of a vane, they will gather to form larger droplets and then drain with gravity. One of the primary differences between mesh pad mist eliminators and vanes is the ability to filter different size droplets. Vanes only work well for larger droplets and work well in high liquid loading situations as opposed to mesh pads that works for smaller droplets.

Vane mist eliminators are also known as chevrons. Typically, they consist of stainless steel, carbon steel, alloy steel, and sometimes plastic. They are constructed of various blades that are spaced to create difficult paths for the gas to follow. Vanes are used in columns, evaporators, and other vessels such as cooling towers, distillation towers. The blades can be smooth or hooked depending on the custom design. With each curve on the blade, the gas flow is forced to change direction, also known as “passes”. Vanes can be vertical or horizontal and are typically are round or rectangular.

Scrubbers in the Fertilizer Industry

The fertilizer industry calls for different chemical process to manufacture different products. These processes generate gases and particulate matter during the process. Many of these processes could release toxins into the atmosphere. Gas cleaning is a common practice to attempt to eliminate these pollutants. Some of the primary purposes of gas cleaning are to recover raw materials, products, and byproducts. Other reasons are to follow guidelines for pollution emission standards set by the local, state, and federal governments and other regulatory agencies.

There are different types of gas cleaning in the form of wet and dry scrubbing. The type of scrubber that is appropriate will depend on the type and size of the particles and components of the gas present. When considering the technologies used to clean the gasses, design, and operation considerations are noted, such as handling characteristics, toxicity, and flammability. All of these will affect the operation of the scrubber. When choosing a scrubber manufacturer, it is important to keep in mind the experience that they offer. The cost of the unit and the budget.

There are several types of wet scrubbers that are common in the fertilizer industry. They are further classified as low, medium, and high energy scrubbers. Choosing a scrubber largely depends on the criteria for the air pollution problem in the fertilizer industry. The following will be taken into consideration, process, type of contaminants, separation efficiency and weather there will be a single-stage or various stages. The following are also very important, the packing type, pressure drop, liquid to gas ratio, temperature, maintenance, costs of installation, and the operation and performance history.

There are also different mechanisms of collection. In a wet scrubber, inertial impaction and interception are the main mechanisms of capturing particulate size particles (> 1 µm in size). Brownian diffusion is used for smaller particles. Larger particles are collected by inertial methods, where droplets will travel powered by inertia and then impact onto the media of the filter. When traveling at a lower momentum, the droplets will be intercepted by the filter media, this is called interception. Brownian diffusion is when sub-micron particles that contain very little mass follow the airstream then they unite until they form larger droplets that will be impacted or intercepted.

Once the scrubber is designed, it must be fitted with packing. Sometimes the packing is random or dumped, and other times it is custom designed. Packing can also be referred to as mist eliminators. It should be noted that not all mist eliminators are designed the same. There are many considerations when choosing a mist eliminator, the size of the droplets, liquid handling, pressure drop, and the compatibility of materials of construction. A properly designed mist eliminator will add many benefits to the process, such as improving product purity, reducing pollution, and reducing carryover, and protecting equipment.

Fiber Bed Filtration – Not all Filters are designed the Same

Optimal filtration is imperative during times of heavy manufacturing and taxing demands on manufacturing plants. It has never been more important to maintain a line of quality filtration to reduce opacity and emissions. Fiber Bed Filters mist collectors are used to trap, collect, and remove liquids and soluble particulate suspended in a gas stream. Fiber bed filters, also known as Candle Filters, Coalescing Filters, or Fiber Mist Collection Systems effectively remove up to 99.9% percent of sub-micron particulates. They are also used to collect insoluble solids. Fiber Bed filters are known to work well in applications such as asphalt, metalworking or oil mist, food processing, chemical processing, acid mist control, and many other industries.

Fiber Bed Filters are designed to provide the final user with many years of optimal performance and minimal operation or maintenance requirements. Typically, these filters are handcrafted and constructed in cylindrical form, filters can range in size from 1 ft to massive in size approaching 20 ft.

The body of the Candle Filter is made of inner and outer cages composed of Carbon Steel, Alloy materials, FRP, and Polypropylene. Depending on your performance indicators, a specific composition of layers will be selected. The filter unit rest on or are suspended from a tube sheet inside a closed tank. The design will aim to optimize efficiency and pressure drop.

Integral prefilters can be provided to improve performance and life of the Candle Filters in the system. Various replacement options are available to facilitate replacement of the prefilter.

Quality Fiber Bed Filters should provide you with low initial pressure drop that results in energy savings. Filters should yield long filter life which means low replacement cost and low maintenance cost. Each filter should be tested in-house to ensure field performance.

Choosing a manufacturer

You should choose a supplier that can manufacturer Fiber Bed Filters to replace your current filters which will provide improved performance and/or filter life. The sales and technical staff should have extensive experience with existing installations allowing them to provide the exact solution you need.

Mechanisms of filtration

When particles larger than 3 microns are prevented from flowing around the fibers they will then strike and collide with the fiber, known as Inertial Impaction.

Generally, particles between 1.0 and 3.0 microns move with less momentum and follow the air stream until they come in proximity and are collected by the fibers and thereby removing them from the air stream, knows as interception.

As extremely fine particles also known as sub-micron particles that contain little mass collide with gas molecules, they will move in a side-to-side motion or random motion also known as Brownian movement This greatly increases the probability of collision with a fiber on the filter.

Basics of an Industrial Scrubber

 With pollution on the rise, the need to abate harmful contaminants and stay in compliance with the Clean Air Act is of upmost importance. For this reason, companies are turning to experienced vendors that focus on air pollution control technologies to help keep them in compliance. While there are many viable options, many times, a wet scrubber fitted with quality mist eliminators will be suggested as a safe and effective way to remove pollutants and odors from exhaust streams. A properly designed scrubber will be highly successful in removing contaminants before they reach the atmosphere, therefore keeping companies in compliance and avoiding shutdowns.

A scrubber system is used in the removal of harmful and hazardous particulates from industrial gas streams before they are released into the environment. Scrubbers can be engineered to safely remove solids, mist, and gases while at the same time providing cooling. Valuable product may also be recovered in the scrubber preventing product loss.

Ease Your Mind – Choose A Company That Specializes In Mist Elimination

Mist is not just something in the air on a rainy day. Mist, which is a danger to your health is formed in chemical and other manufacturing processes. When it comes to health and safety, imagine mist as the suspension of chemicals and combustible liquids in lingering the air. It will settle in wherever it lands, corrode machinery and cars, and possibly cause irreversible health concerns.

Responsible companies will invest heavily in capital equipment and internals to abate harmful mist and remove mist from the gaseous phase. Typically, this investment will come in the form of mist eliminations. When crossing this path, it is wise to choose a company that specializes in mist elimination.

The need to separate mist droplets from the gas stream in industrial chemical processes is one of the most common occurrences in unit operation. This is achieved by using mist eliminators or demisters. A mist eliminator, also known as a demister, should meet the needs of the customer both technically and commercially, therefore you need to know what you as the client want to achieve.
