Major developments to be analyzed in Hot Gas Filtration March 19th Hot Topic Hour
Due to the hydrate conference scheduled on this date , the discussion of dry scrubbing has been moved to April 9. The March 19 session will be split in two segments: Systems and Components.
Systems: We are being bombarded with new technologies and approaches which remove particulate and even NOx and acid gases at 850F. If these technologies live up to their claims, they will change the entire back end layout of power plants.
On March 19, we will provide updates on systems previously analyzed and presentations on additional options. Martin Schroter, Senior Manager of Business Development, Duerr Systems Inc. will describe the ceramic catalytic filter using sub-micron powdered limestone injection in the furnace to provide the acid gas reagent.
Mitchell Krasnopoler, Manager, Air Quality, Kiewit Power Engineers & Construction will provide an analysis of removal options.
Haldor Topsoe and FLS have introduced two products. One is a ceramic catalytic filter element to operate at 850F. The other is a three layer synthetic filter bag with tailored catalysts in each layer to oxidize VOCS and reduce NOx. We hope to obtain greater insights on both of these products.
We will be reviewing options for coal fired boilers in the U.S. China and elsewhere. We will also be discussing cement and other applications. One major application is coal gasification where Porvair has orders for its metal filters. China plans to convert 1.5 billion tons of coal to syngas and chemicals. This program would require hundreds of millions of dollars of annual investments in elements to filter more than 1 billion cubic feet of gas per minute.
This webinar will build on one conducted on Sept 4, 2014 and a free website - Hot Gas Filters - Continuous Analyses. This free website also includes the analysis of filter elements which are operating in the 350F regime. A webinar on the options and issues for this temperature range was conducted and recorded on January 8, 2015.
Face to face discussions of the options for both temperature regimes will be conducted on April 29 at 10:00am in Charlotte N.C at the AFS Power conference. The website will be continually populated with a decision tree system with all the options explored. A series of articles in Filtration News will provide summaries of the latest developments.
Components: Short presentations will be given by:
Joseph (Joe) Riley, President, BoldEco Environment on filter optimization
Stewart McKenzie, Sales Manager, Lechler on humidification (reference EUEC speech)
Blaz Jurko, Gebr. Pfeiffer, Inc., on limestone size reduction. He will be asked to comment on the sub micron size utilized in the Duerr system and compare it to the size in the conventional dry grinding systems.
