Precise manufacturing - Meet the optimum filtrationperformance by controlling characteristicsLooking for the perfect upgrade of your liquid application? Altering shape, porosity, construction material, and other factors, complete functional control over a wide range of properties is provided to meetthe optimum performance.Overview of precision sintered porous metal filter elements1. Primary design considerationsAll porous products, whatever the material of construction, have specific properties which must be taken intoaccount in design and manufacturing processes.In order to select the best media for any application, one should be able to provide Bekaert with the following information: Primary application considerations- Primary media considerationsDesired particle retentionProcess temperaturePressure dropSystem pressureFlow rateCorrosive effects, if anyCleanliness requirementsOperating fluid - type, density, viscosity-In some cases, the best choice of media isknown for the application. Standard products aredesignated by shape and media grade, but othercharacteristics may be altered to “fine tune”product performance:Mean pore sizePore size distributionDensityOur porous metal filter elements are manufactured in a broad range of materials and sizes, and with a selectionof fittings, so they can be easily specified with the characteristics and configurations customers require. Customfeatures can be incorporated or completely original designs can be created for specific needs.2. Construction featuresPorous metal filter elements are manufactured in a wide variety ofconfigurations including open-end, closed-end, and with weldedhardware and fittings. Standard products can be configured to customize a design to meet specific process needs.123Media configurationFilter element designSystem proposalSome applications Catalyst recovery in chemical and petrochemical processesPolishing in food & beverages (syrups, liquors)Catalyst removal from flavour ingredients and other food specialtiesSteam filtration in pharmaceutical and food & beverage processes 4BEK liquid filtration 8pag.indd 429-05-2012 17:29:07
HyPulse *: high performance, high strength filtrationof liquidsHyPulse * filter systems are completely tuned in on your specific filtration process and enable you toreduce an entire train of process filtration steps to one single stage.From lab development to design and constructionLaboratory and on-site evaluations provide a sound base for filter design. Our mobile filter systems and on-site testingassistance make it possible to analyze your needs on the spot, in order to configure our solution to your application.12Lab developmentFilter system design usually begins at theBekaert laboratories, where the results ofsmall-scale runs are analyzed, using actualsamples provided by customers.Pilot scale testThe next step is a pilot-scale filter at thecustomer’s site to ensure compatibility withactual process conditions.3Final productOnce final operating conditions aredetermined, the full-scale productionsystem is shipped and installed, afterwhich on-line performance is audited.Product rangePorous metal powder filter elements are offered with the widest selection of filter media, ranging from standard316L stainless steel to corrosion resistant nickel and Hastelloy .AdvantagesEasy cleaningPorous metal filters are easilyfreed of particulate by usingbackwash cleaning methodswithout scraping, scrubbing,or rotating filter elements.Contaminants may also beremoved with water, steam, air,solvents, caustic or acid washing,or with ultrasonic cleaning.Completely enclosedBackwashing filter elementsreduce operator exposure tohazardous chemicals.High temperature andcorrosion resistanceSintered metal elements areresistant to high temperaturesand/or corrosive environments,making them suitable for a widerange of applications.Uniform, high-precision porosityControlled pore size and poredistribution to create filtrationmedia with distinct porositycharacteristics.Waste minimizationCleanable filter elementseliminate incineration orlandfill costs associatedwith disposable filters.High-strength filter elementsSintering bonds filter mediatogether at the molecular level,resulting in high mechanicalresistance in compression andstress.Reduced spare parts expensePorous metal filter elementsseldom need replacing.Minimal maintenancePorous metal filters have nomoving parts, resulting in simplerand less frequent maintenanceprocedures.* HyPulse is a registered trademark of Mott Corporation5BEK liquid filtration 8pag.indd 529-05-2012 17:29:11
Discover the possibilities of HyPulse * filter systemsHyPulse * filter systems can be designed to handle high flow rates in continuous operations typical in refineryapplications. Hot hydrocarbon streams such as FCCU slurry oil often require removal of catalysts and otherparticulate. This not only improve the oil product, it also improves downstream operating equipment bypreventing fouling and reducing maintenance.Target in refineryA key goal for removing the catalyst particulate is the upgrading of product fuel oils to provide feedstock forproduction of carbon black, needle coke, hydrotreater, coker feed, bunker oil amongst others. Removing thecatalyst fines also reduces the wear of downstream components due to the abrasive nature of the particles,prevents settling and sludge formation in slurry oil storage tanks in addition to concerns over the hazardouswaste classification of catalyst-containing tank sediments.Typical filtration system & backwash operationFiltration is operated through a HyPulse * LSI filter system consisting of two filter vessels, a backwash receiver, anda gas stabilizer tank, with supporting piping, valves, and instrumentation. The filter vessels each contain cylindricalporous metal filter elements that are open at the bottom and closed at the top. The filter elements are 2” diameterand length 70-80”, 0.5 micron grade, AISI 316L porous metal media. These removable filter elements are threadedinto the filter vessel tube sheet. The filter system is designed for continuous operation with both filters on-lineexcept when one filter is off-line for backwash. The backwash receiver provides surge volume to containbackwashes and is sized to hold 2 backwashes.After the filtration phase, filter backwash is initiated by interrupting the feed stream and isolating the filter vessel.The filtrate in the vessel shell may be displaced with an alternate backwash fluid, typically cycle oil. The filtervessel is then pressurized with nitrogen or refinery gas from the stabilizer tank to reach the backwash pressure.The bottom discharge valve is opened and the applied pressure drop and reverse flow through the filter elementsdislodges the cake and the vessel drains to the backwash receiver. After the backwash is complete, the filter isready to begin the next online cycle. The backwash slurry, which has 15-20% solids content, is pressured at a controlled low flow rate to the FCC riser, or may be sent to an asphalt plant, a low-grade coke plant, or a settling tank.Dual filter vesselsSlurry discharge valveLiquid receiver vessel* HyPulse is a registered trademark of Mott Corporation6BEK liquid filtration 8pag.indd 629-05-2012 17:29:12

EMI FILTER There are several types of filters, for example, passive EMI filter, active EMI filter and hybrid EMI filter. However, the passive EMI filter is simpler than others. A typical procedure used in [4, 5] is considered to design power line EMI filter. A basic network topology is used, C-L-C for DM filter and L-C
