Filtration is all important in the market of chemical and petrochemical production, ensuring product quality and lowering production costs. Over 4 decades, Fileder has been working within these industries learning the key challenges and developing a vast product portfolio,

able to tackle even the most challenging requirements. Chemicals for Filtration

Chemical plants are highly sensitive to contaminants and the quality of raw materials used to produce the desired chemical can influence this. Even the smallest fluctuation in what has been accepted as standard may significantly impact the final product quality, consequently influencing production and maintenance costs. Efficient filtration is therefore mandatory for any chemical plant as it can both mitigate these risks and ensure the brand reputation remains intact.

The Challenges In this guide we will focus on the challenges most commonly CHEMICAL INDUSTRY: CHEMICAL faced within the chemicals industry, including:

• Unwanted particulate that affects the chemical in service • Visual effects from contaminants • Pure water dilution and feed water purification • Removal of elements leaching from onsite systems affecting the product • Control of bacterial contamination • Control of gelatinous, congealed lumps in viscous products • Final product appearance and quality • Site facilities including boiler efficiency

There are many possible filtration processes and configurations that could be applied within the common stages of chemical production. Whether this includes filtration of raw materials to prevent bacteria contamination in storage tanks, production of pure water for boiler feed and wash water, or clarification and final product filtration.

The Fileder product portfolio covers all these requirements, offering excellent performance and product reliability throughout.

The production of chemicals can generate contamination at any stage during the process. It is therefore important to ensure that filtration technology is not only applied to filter raw materials but also later, protecting all downstream chemical processes .

The range of raw materials requiring filtration can be vast, ranging from solvents, acids and bases to complex chemicals; but in their simplest form, raw materials need to be filtered so that bulk and smaller particles are removed from the product. Fileder recommends that the applied strategy should involve more than just one filtration stage and this could include either bag or depth filtration technology, depending on the loading volumes being filtered.

If the correct filtration method is initially applied, it will ultimately minimise the need for filtration and added costs at a later stage.

The clarification stage is normally performed later in the manufacturing process, before preparation of the product for final filtration and packaging.

As with the raw materials stage, clarification also includes particle removal, in this instance finer particulate.

Multiple filtration stages may be required here to achieve the final filtration goal. Typically, a cascade of filtration will be used, utilising lower efficiency filters to remove larger contaminants, followed by higher efficiency pleated filters to remove finer particulate or suspensions.

The Premier bag filters (PBP) feature a multi-layered construction, which ensures high levels of dirt holding, whilst the microfibre media and flanged neck lessen the risk of particle bypass.

Final filtration is the key and most critical stage of the manufacturing process. The quality of the final product depends on the effectiveness of the filtration employed here. The goal is to remove any particles that will affect the final product quality, and there can be wide variations in the type and amount of contaminants across three key areas:

• Bulk chemicals may only require large particulate to be removed, therefore a high flow rate prior to packing may be beneficial • Speciality chemicals may require targeted filtration, removing morphing gels and particles at an exact micron rating • Finally, high purity chemicals may require removal of all particles down to sub-micron levels

Partially Open Blocked Pore Pore

Particulate smaller than the micron rating of the cartridge can sometimes be filtered from the incoming fluid. Specialised cartridges, Smaller particulate such as the CP2, are designed with an advanced fibre matrix to reduce retained Smaller the effects of micron rating creep as illustrated, right. particulate Flow pass through Flow Flow

When selecting the correct filter and housing for your chemical filtration challenge, chemical compatibility is paramount. Consideration not only needs to be given to the filter media, but also sealing gaskets and O-rings for both filters and housings.

To aid this, Fileder have compiled a simple to use chemical compatibility guide for all main products listed for chemical filtration within this brochure. The guide is broken down to the key products within each stage of the chemical manufacturing process, making selection of the right housing and filter straightforward.

The chemical resistance data detailed above was obtained from numerous sources in the industry. No testing was carried out by Fileder. The resistance guide should be used as guidance only and not as a guarantee of chemical compatibility. We do not assume any liability for the accuracy or completeness of the information. It is recommended that the users should perform their own tests to determine suitability of the product. The compatibility data is based on the fluid and material being a static state at a maximum temperature of 25oC.

In chemical applications, it is important to consider the compatibility of not only the filter and housing, but also every component that comes into contact with the fluid; this includes the O-ring or seal. Teflon O-rings from Fileder are constructed with a silicone core coated in PTFE for increased flexibility whilst offering resistance to most chemicals such as acids, bases and oils.
