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 Typical Technologies Applied Bag Depth Surface Softening Reverse UV Systems For T&C's, Terms of Use and Copyright, please visit www.fileder.co.uk Filtration Filtration Filtration Osmosis www.fileder.co.uk • 01622 691886 • [email protected] 3 Simplified Filtration Setup at a Chemical Plant Raw Water Tank Organics & Hardness Removal Particle Removal Chlorine Removal PWS Softener SFH-SPC + SSP SFH-SPC + SCB-S Tank Vent Filter PPPTFE Ultraviolet Disinfection SUV-S Particle Removal SFH-SPC + SSP Boiler Feed Purified Water Storage Tank Process Water & Boiler Feed Setup Raw Material Filtration Clarification Stage Final Filtration Final Filter Bulk Filling Packaging (Polishing) Key Machine PFH-SPC + PPP 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 . 4 www.fileder.co.uk • 01622 691886 • [email protected] Simplified Filtration Setup at a Chemical Plant Raw Component Tank DI Water Bulk Particulate RO Water System Production Removal SRO-SYS SV-FK + Resin SBH-SPC + EBSN Mixer Reactor Bacterial Grade Filter PFH-SPC + PPPES Wash Water Finer Particulate Bulk Particulate Storage Tank Removal Filter Removal SFH-SPC +SSP97 SBH-SPC + PBP Raw Materials Final Filtration Clarification www.fileder.co.uk • 01622 691886 • [email protected] 5 Raw Material Filtration 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.

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.

  • Introduction to Separation Processes What Is Separation and Separation Processes ?
    Introduction to Separation Processes What is Separation and Separation Processes ? • Separate (definition from a dictionary) - to isolate from a mixture; [extract] - to divide into constituent parts • Separation process - In chemistry and chemical engineering, a separation process is used to transform a mixture of substances into two or more distinct products. - The specific separation design may vary depending on what chemicals are being separated, but the basic design principles for a given separation method are always the same. Separations • Separations includes – Enrichment - Concentration – Purification - Refining – Isolation • Separations are important to chemist & chemical engineers – Chemist: analytical separation methods, small-scale preparative separation techniques – Chemical engineers: economical, large scale separation methods Why Separation Processes are Important ? • Almost every element or compound is found naturally in an impure state such as a mixture of two or more substances. Many times the need to separate it into its individual components arises. • A typical chemical plant is a chemical reactor surrounded by separators. Separators Products Reactor Separator Raw materials Separation and purification By-products • Chemical plants commonly have 50-90% of their capital invested in separation equipments. Why Separation is Difficult to Occur? • Second law of thermodynamics - Substances are tend to mix together naturally and spontaneously - All natural processes take place to increase the entropy, or randomness, of the universe

  • 7 Secrets to a Well-Run Plant a Guide for Plant Managers and Operations Staff
    WHITE PAPER Making Confident Decisions in Operations: 7 Secrets to a Well-Run Plant A Guide for Plant Managers and Operations Staff Terumi Okano, Aspen Technology, Inc. Have you ever received a call in the middle of the night because of a plant operational crisis? The production engineer responsible for the process is already onsite but they really need your advice and will likely also need support from the process engineering team. You can almost see the lost revenue growing as the plant drifts further from its Key Performance Indicators (KPIs). Detailed simulation models are likely already used by the process engineering or modeling team who support your plant in solving these kinds of complex process issues. Your production engineers certainly don’t have the time to learn new software to build detailed models. What you may not know is that sophisticated modeling technology can be accessed by your team through an easy-to- use, Microsoft Excel® interface. Model-based decision-making can apply to plants of nearly every type ranging from ethylene to polymers, fertilizers and specialty chemicals. The following seven secrets explain how building a model-based culture in your plant will bring clarity and continuous improvements to plant operations. Secret #1: Conceptual design models can assist plant operations. Do you know how or where the design work was done for your chemical plant? If you are able to find the conceptual design work that was completed with process simulation software, you’re already one step ahead. If it’s been decades since the plant was built and there is no design work 1to be found, start with asking for simulation models of problematic pieces of equipment or a section of your process that can be unreliable.

(Rrreiwd 28 May 1987; final revision received 26 June 1989; received for publicarion 11 July 1989) Abstract-We describe the design, development and testing of a prototype simulator to study problems associated with robust and efficient solution of dynamic process problems, particularly for systems with models containing moderately to very stiff ordinary differential equations and associated algebraic equations. A new predictor-corrector integration strategy and modular dynamic simulator architecture allow for simultaneous treatment of equations arising from individual modules (equipment units), clusters of modules, or in the limit, all modules associated with a process. This “sequential-clustered” method allows for sequential and simultaneous modular integration as extreme cases. Testing of the simulator using simple but nontrivial plant models indicates that the clustered integration strategy is often the best choice, with good accuracy, reasonable execution time and moderate storage requirements.

  • Student-Designed Case Studies for Chemical Reaction Engineering Course Projects
    Choose Your Own Kinetics Adventure: Student-Designed Case Studies for Chemical Reaction Engineering Course Projects Ashlee N. Ford Versypt School of Chemical Engineering, Oklahoma State University Abstract This paper presents an innovative approach for a chemical reaction engineering course project. The project tasks students to conduct the preliminary design of a reactor or series of reactors to produce a chemical product of their choice. The constraints on this open-ended “choose your own project” are that the chosen process must involve a catalyst, multiple reactions, and heat transfer. The students must use published kinetics and physical property data from the literature, heat and mass balances, and software to complete their design. Students work in groups and write a report summarizing their findings. The activity connects course concepts to real world applications and requires students to design their own case studies through exploring the research and patent literature. These aspects engage students in topics they are interested in while simultaneously relieving the burden off of faculty for constructing new projects each course offering. Introduction Problem-based learning and laboratory experiments are common teaching methods for the undergraduate kinetics and reaction engineering courses in chemical engineering (Silverstein 2011). However, these approaches typically are concentrated on one course topic at a time. Most problems that can be found in the common reaction engineering textbooks, such as Folger’s text that is widely used in the field (Silverstein 2011), tend to focus on topics related only to isolated segments of the text. For example, a problem involving a catalytic rate law can only be found in the few chapters dealing explicitly with catalysis.

  • Chemical Plant
    CHEMICAL PLANT BASF Chemical Plant Portsmouth Site in the West Norfolk area of Portsmouth, Virginia, United States. The plant is served by the Commonwealth Railway. A chemical plant is an industrial process plant that manufactures (or otherwise processes) chemicals, usually on a large scale. The general objective of a chemical plant is to create new material wealth via the chemical or biological transformation and or separation of materials.[1] Chemical plants use special equipment, units, and technology in the processes. Other kinds of plants, such as polymer, pharmaceutical, food, and some beverage production facilities, power plants, oil refineries or other refineries, natural gas processing and biochemical plants, water and wastewater treatment, and pollution control equipment use many technologies which have similarities to chemical plant technology such as fluid systems. Some would consider an oil refinery or a pharmaceutical or polymer manufacturer to be effectively a chemical plant. Petrochemical plants (plants using petroleum as a raw material) are usually located adjacent to an oil refinery to minimize transportation costs for the feedstocks produced by the refinery. Specialty chemical plants are usually much smaller and not as sensitive to location. Chemical processes Chemical plants typically use chemical processes, which are detailed industrial- scale methods, to produce the chemicals. The same chemical process can be used at more than one chemical plant, with possibly differently scaled capacities at each plant. Also, a chemical plant at a site may be constructed to utilize more than one chemical process. A chemical plant commonly has usually large vessels or sections called units that are interconnected by piping or other material-moving equipment which can carry streams of material.
