International refractory manufacturer RATH will be represented at the Hotbels Seminar on April 18 and 19 in Lexington (USA) with an expert lecture on hot gas filtration in the glass industry.
Manfred Salinger, Director Advanced Ceramic Filtration Solutions RATH Group, will present a holistic approach to emission control and heat recovery at his lecture. In addition the proven expert on hot gas filtration will review the experience gained and the key to reliable operation and long service life of filter elements.
High-temperature filters are key components in emission control and heat recovery solutions. In many thermal process facilities, the clean-up stage cools the exhaust gases to low temperatures that are insufficient for re-use. Cleaning of exhaust gases at elevated temperatures of up to 1400 degrees Fahrenheit allows the gas to be re-used in thermal processes or for power generation.
In order to reduce the footprint of the emission control equipment, hot gas filters can now be equipped with ceramic filter elements up to 20 feet long. The new generation of longer filter elements lowers capital investment costs while maintaining the important functions of particulate removal and selective catalytic reduction of nitrogen oxides.
In his presentation, hot gas filtration expert Manfred Salinger will compare the improved emission control system with the conventional solution, introduce the range of available filter element lengths and review the lessons learned and the keys to reliable operation and long service life of the filter elements.
For many years, RATH has been developing innovative ceramic hot gas filter elements, which make it possible to filter particle-laden industrial flue gases at temperatures up to 1000 degrees Celsius and to reduce emissions of nitrogen oxides.
Since 2016, all resources, capabilities and know-how in hot gas filtration have been pooled in the Meißen facility, Germany. This RATH research and production site is home to cutting-edge facilities for the manufacture of RATH’s FILTRATH® hot gas filter cartridges and FILTRATH®CAT catalytic filter elements. The latter were developed for pollutant emission control: These rigid yet highly porous and catalytically coated ceramic filter elements are used for multiple pollutant control of (fine) dust, acid gases, dioxins and nitrogen oxides in hot gas flows (at temperatures of 250 to 420 degrees Celsius) and can easily replace conventional textile filters.
Doubling of the production capacity for hot gas filter elements in Meißen Recently, RATH has doubled its production capacity for both catalytic and non-catalytic hot gas filter elements at its Meißen production facility. As the only remaining European manufacturer of filter elements, RATH can produce up to 40.000 filter elements per year depending on requested dimensions and quality. The new production line is already in operation and running at the highest efficiency level.
