CERAMIC FILTER SYSTEMS
INTRODUCTION Low-density ceramic filter elements were developed over 10 years ago and have seen substantial usage growth and consistent application success, particularly in the past five years. This success is attributed to a better understanding of ceramic filter elements, the availability of high-quality ceramic filter elements, better filter system design and improved plant design / operation. Industrial Catalytic Engineering (UK), [ICE (UK) Ltd.], and Brightcross of the United Kingdom have been instrumental in the design and production of high-quality ceramic filter elements; the dividends being sales of over 50,000 elements within the last 2 years. Brightcross of the United Kingdom is a market leader in the manufacture of vacuum formed high temperature foundry consumables and living flame gas fire products. The company has a total current product line of over 1,500 individual items and produces over 15 million pieces per year. ICE (UK) Ltd. became involved in low-density ceramic filter elements in 1996 when they were approached by Brightcross to design and develop a ceramic filter element, which could address numerous problems being experienced with ceramic filter elements available at that time. Problems such as: poor strength at high temperatures, geometrical inaccuracy, poor sealing, bending, corrosion, poor cleaning, short element life, etc. had to be addressed. With extensive research and development and with access to actual applications, ICE (UK) Ltd. and Brightcross of the United Kingdom developed the first generation of the BX C 1000/60 elements, which resolved these problems. Traditionally, these ceramic filter elements are vacuum formed from a slurry mixture of water, ceramic or mineral fibers and binding agents. Brightcross of the United Kingdom can vary the element size, composition and the properties of the element to suit almost any application at the time of manufacture. BX Series Ceramic Filter Elements of differing dimensions, compositions and properties are operating successfully in various applications throughout the world. ICE (UK) Ltd. can provide the technical and engineering support required when specifying and designing ceramic filter systems, from the initial technical requirements to full CAD design, through to full manufacture, installation and commissioning if required. With over 14 years of experience in controlling emissions from a wide range of processes, ICE (UK) Ltd. offers many products for controlling environmental pollutants including: SOx, HCl, HF, NOx, Dust, Heavy Metals and organic compounds including Dioxins and VOC's. Now, by exclusive agreement, Sun Combustion, Inc. can offer this unique ceramic filter element technology and ICE (UK) Ltd.'s other products and capabilities in the USA and Canada. The future aims of this alliance are to offer additional innovative products, systems and complete solutions to our customers and to assist them in achieving environmental compliance at a reasonable cost. Whether our customers require a fully responsive turnkey package with comprehensive "After the Sale Service" or just replacement products for their existing plants, again with "After the Sale Service", both Sun Combustion, Inc. and ICE (UK) Ltd. stand ready to provide the necessary technical expertise and operational advice to them. BENEFITS Here are some of the benefits of low-density ceramic filter elements and some of the relative advantages of the BX Series Ceramic Filter System product line. High Filtration Efficiency
Unlike bags, the dust cake on the outer surface of the ceramic filter element is not completely removed on reverse cleaning; it is this continuous dust cake that gives the BX Series Ceramic Filter System its high filtration efficiency (>99.99%).
Uninterrupted Dry Scrubbing
Another benefit of the continuous cake is that if dry scrubbing for acid gases is employed, some sorbent is always present on the surface providing uninterrupted dry scrubbing.
Self Supporting
The BX Series Ceramic Filter System's elements are of a monolithic design, which means they are self-supporting; therefore support cages are not required as on a bag type filter element.
Spark Resistant and Non-Combustible
Due to their composition, BX Series Ceramic Filter Systems are spark resistant and non-combustible.
Strength and Integrity
The predominantly inorganic binder system, utilized in the BX Series Ceramic Filter System's element, ensures excellent high temperature strength retention (>1000ºC).
Fully Machined, Excellent Sealing, Uniform Dust Deposition
All BX Series Ceramic Filter System elements are fully machined to very tight dimensional tolerances which guarantees a perfect fit every time, provides excellent sealing qualities and assures a uniform wall thickness thus giving uniform dust deposition.
Very Low Initial Pressure Drop
The very low initial pressure drop of the BX Series Ceramic Filter System's element aids in the efficiency of the reverse pulse type cleaning system. The very low pressure drop is illustrated on the following graph with respect to face velocity. Figures are for any single unused element tested at ambient temperature.
Uniform Performance
The pressure drop in the BX Series Ceramic Filter System's element is not only low, but the desired pressure drop is purposely designed into the ceramic filter element and can be varied, within controlled parameters, at time of manufacture; this capability provides uniform performance across the whole filtration area. The unique tapered design enables better flow characteristics, both on deposition and cleaning, therefore helping to avoid dust plugs.
Bag Filtration System Retrofit
The BX Series Ceramic Filter System has proven to give a realistic bag filtration system retrofit alternative.
Acid Resistant
The composition of the BX Series Ceramic Filter System's element offers excellent resistance to acid gases.
HF Resistant
The presence of high concentrations of HF has proven in the past to significantly reduce element life, particularly if operating temperatures fall below the acid dew point. The unique composition of the BX Series Ceramic Filter element has proven to offer relatively longer life in the presence of dry HF.
