Advantages

• Long life In most applications, porous metal powder maintains high filtration efficiency through years of continuous use.

• High strength Porous metal media are unsurpas-sed in tensile strength, making them well suited for high differen-tial pressures and flow rates.

• Uniform porosity A strictly controlled sintering pro-cess enables to produce uniformly sized and distributed pores, in media grades ranging from 0.2 to 20 μ.

• Fully cleanable Particles may be removed from po-rous metal media using backwash and other cleaning methods, res-toring the media to its original ef-ficiency for repeated performance.

• No media migration “Solid -state diffusion bonding” holds filter media together at the molecular level, making it virtually inseparable, even under the har-shest conditions

• High temperature tolerance All metal construction and welded seams endure high temperatures, even in oxidizing atmospheres.

Precise manufacturing - Meet the optimum filtration performance by controlling characteristics

Looking for the perfect upgrade of your liquid application? Altering shape, porosity, construction mate-rial, and other factors, complete functional control over a wide range of properties is provided to meet the optimum performance.

1. Primary design considerations

• Primary application considerations - Desired particle retention - Process temperature - Pressure drop - System pressure - Flow rate - Corrosive effects, if any - Cleanliness requirements - Operating fluid - type, density, viscosity

• Primary media considerations - In some cases, the best choice of media is known for the application. Standard products are designated by shape and media grade, but other characteristics may be altered to “fine tune” product performance: - Mean pore size - Pore size distribution - Density

Overview of precision sintered porous metal filter elements

All porous products, whatever the material of construction, have specific properties which must be taken into account 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:

2. Construction features

Porous metal filter elements are manufactured in a wide variety of configurations including open-end, closed-end, and with welded hardware and fittings. Standard products can be configured to custo-mize a design to meet specific process needs.

Media configuration Filter element design System proposal

Our porous metal filter elements are manufactured in a broad range of materials and sizes, and with a selection of fittings, so they can be easily specified with the characteristics and configurations customers require. Custom features can be incorporated or completely original designs can be created for specific needs.

Precise manufacturing - Meet the optimum filtration performance by controlling characteristics

HyPulse®*: high performance, high strength filtration of liquids

HyPulse®* filter systems are completely tuned in on your specific filtration process and enable you to reduce an entire train of process filtration steps to one single stage.

From lab development to design and construction

Laboratory and on-site evaluations provide a sound base for filter design. Our mobile filter systems and on-site testing assistance make it possible to analyze your needs on the spot, in order to configure our solution to your application.

Lab developmentFilter system design usually begins at the Bekaert laboratories, where the results of small-scale runs are analyzed, using actual samples provided by customers.

Pilot scale testThe next step is a pilot-scale filter at the customer’s site to ensure compatibility with actual process conditions.

Final productOnce final operating conditions are determined, the full-scale production system is shipped and installed, after which on-line performance is audited.

Product range

Porous metal powder filter elements are offered with the widest selection of filter media, ranging from standard 316L stainless steel to corrosion resistant nickel and Hastelloy®.

Easy cleaning

Porous metal filters are easily freed of particulate by using backwash cleaning methods without scraping, scrubbing, or rotating filter elements. Contaminants may also be removed with water, steam, air, solvents, caustic or acid washing, or with ultrasonic cleaning.

Completely enclosed

Backwashing filter elements reduce operator exposure to hazardous chemicals.

High temperature and corrosion resistance Sintered metal elements are resistant to high temperatures and/or corrosive environments, making them suitable for a wide range of applications.

Uniform, high-precision porosityControlled pore size and pore distribution to create filtration media with distinct porosity characteristics.

Waste minimizationCleanable filter elements eliminate incineration or landfill costs associated with disposable filters.

High-strength filter elementsSintering bonds filter media together at the molecular level, resulting in high mechanical resistance in compression and stress.

Reduced spare parts expensePorous metal filter elements seldom need replacing.

Minimal maintenancePorous metal filters have no moving parts, resulting in simpler and less frequent maintenance procedures.

Discover the possibilities of HyPulse®* filter systems

Target in refinery

HyPulse®* filter systems can be designed to handle high flow rates in continuous operations typical in refinery applications. Hot hydrocarbon streams such as FCCU slurry oil often require removal of catalysts and other particulate. This not only improve the oil product, it also improves downstream operating equipment by preventing fouling and reducing maintenance.

A key goal for removing the catalyst particulate is the upgrading of product fuel oils to provide feedstock for production of carbon black, needle coke, hydrotreater, coker feed, bunker oil amongst others. Removing the catalyst 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 hazardous waste classification of catalyst-containing tank sediments.

Typical filtration system & backwash operation

Filtration is operated through a HyPulse®* LSI filter system consisting of two filter vessels, a backwash receiver, and a gas stabilizer tank, with supporting piping, valves, and instrumentation. The filter vessels each contain cylindrical porous metal filter elements that are open at the bottom and closed at the top. The filter elements are 2” diameter and length 70-80”, 0.5 micron grade, AISI 316L porous metal media. These removable filter elements are threaded into the filter vessel tube sheet. The filter system is designed for continuous operation with both filters on-line except when one filter is off-line for backwash. The backwash receiver provides surge volume to contain backwashes 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 filter vessel 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 elements dislodges the cake and the vessel drains to the backwash receiver. After the backwash is complete, the filter is ready to begin the next online cycle. The backwash slurry, which has 15-20% solids content, is pressured at a con-trolled low flow rate to the FCC riser, or may be sent to an asphalt plant, a low-grade coke plant, or a settling tank.
