Catalytic fabric filtration for simultaneous NO{sub x} and particulate control. Final report

Abstract

Corporation (OCF) for supporting the pilot-scale evaluation of the catalytic fabric filter concept. Also, the EERC would like to thank Raytheon Engineers & Constructors (RE&C) for their efforts in the completion of Task 4, Conceptual Design and Economic Evaluation, and their overall project technical support. The EERC Project Manager would like to specifically thank Ms. Felixa Eskey (DOE-PETC), Mr. Jack Pirkey (Con Edison), Dr. Aubrey Messing (ESEERCO), Ms. Debra DiMeo (ESEERCO), Dr. Patrick Aubourg (OCF), Ms. Marie Kalinowski (OCF), and Mr. Russ Potter (OCF) for their support and input concerning the catalytic fabric filter evaluation effort. Also, the efforts of Mr. Tony Taladay (RE&C) and Mr. Cameron E. Martin (RE&C) are gratefully acknowledged for their completion of Task 4 and overall project support. The EERC Project Manager, Mr. Greg Weber, would like to thank Mr. Grant Dunham, Mr. Dennis Laudal, Ms. Sumitra Ness, and Mr. Grant Schelkoph for their efforts in completing the various project tasks and contributing to the preparation of this final project report. The authors also gratefully acknowledge the efforts of a large number of EERC support staff who were instrumental in the completion of the experimental work as well as in the preparation of this final project report. Special recognition is due Mr. LeRoy Sbndrol for making the University of North Dakota (UND) steam plant available in support of Subtask 3.4-Fabric Durability Testing/Pulse-Jet System and Mr. Ray Tozer Jr. and the UND steam plant personnel for providing assistance with the day-today monitoring of the baghouse slipstream system operation.

Catalytic fabric filtration for simultaneous NO[sub x] and particulate control

“…The views and opinions of authors expressed herein do not necessarily state or reflect those of the United States Government or any agency thereof. Bench-scale experimental results have shown that over 90% NO, removal can be achieved, the catalyst/fabric has promising self-abrasion characteristics, and the potential exists for substantially reduced cost when compared with conventional SCR/fabric filtration technology (6,7). However, development of the technology requires further evaluation of air-to-cloth ratio effects, ammonia slip, SO2 oxidation to S03, temperature cycling, catalyst-coated fabric preparation, fuel impacts, fabric cleaning (reverse-gas versus pulse-jet), catalyst life (poisoning and resistance to erosion), and filter performance/life (particulate control, differential pressure, and durability).…”
