This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the study was to develop a data base on selective catalytic reduction (SCR) applications on small natural gas-fired prime movers with emphasis on SCR system performance and costs. Major sources of information included telephone contacts with the SCR sites, SCR system suppliers, and engine/turbine manufacturers. Eleven SCR units were identified as operational at seven sites on gas turbines. All were base load cogeneration facilities. On internal combustion (IC) engines, 13 SCR units at nine sites are operational (three cogeneration and ten gas compression/transmission/distribution). Nine of the units are variable load applications. Two principal SCR system problems identified include lack of reliability for continuous emission monitors (CEMs) and catalyst failures due to either structural integrity or poisoning. Total installed capital costs for SCR systems on combustion turbines showed a smooth decrease from 140 to 40 $/hp for the 4,300 to 12,000 hp size range. Catalyst costs were about 30 to 40 percent of the total installed costs. IC engine SCR costs ranged from 20 to 250 $/hp, with no apparent correlation with engine size (350 to 6,710 hp).

This book was released on 1992 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project is to demonstrate and evaluate commercially available Selective Catalytic Reduction (SCR) catalysts from US, Japanese and European catalyst suppliers on a high-sulfur US coal-fired boiler. SCR is a post-combustion nitrogen oxide (NO[sub x]) control technology that involves injecting ammonia into the flue gas generated from coal combustion in an electric utility boiler. The flue gas containing ammonia is then passed through a reactor that contains a specialized catalyst. In the presence of the catalyst, the ammonia reacts with NO[sub x] to convert it to nitrogen and water vapor. Although SCR is widely practiced in Japan and Europe, there are numerous technical uncertainties associated with applying SCR to US coals. These uncertainties include: (1) potential catalyst deactivation due to poisoning by trace metal species present in US coals that are not present in other fuels. (2) performance of the technology and effects on the balance-of-plant equipment in the presence of high amounts of SO[sub 2] and SO[sub 3]. (3) performance of a wide variety of SCR catalyst compositions, geometries and methods of manufacture under typical high-sulfur coal-fired utility operating conditions. These uncertainties will be explored by constructing a series of small-scale SCR reactors and simultaneously exposing different SCR catalysts to flue gas derived from the combustion of high sulfur U.S. coal.

Book Synopsis Selective Catalytic Reduction of NOx by : Oliver Kröcher
Download or read book Selective Catalytic Reduction of NOx written by Oliver Kröcher and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The most efficient process to reduce NOx emissions from lean exhaust gases, selective catalytic reduction (SCR) with ammonia, has undergone tremendous development over the past decades. Originally only applied in stationary power plants and industrial installations, SCR systems are now installed in millions of mobile diesel engines, ranging from off-road machineries, to heavy-duty and light-duty trucks and passenger cars, to locomotives and ships. All of these applications involve specific challenges due to tighter emission limits, new internal combustion engine technologies, or alternative fuels. Three review articles and 14 research articles in this book describe recent results and research trends of various aspects of the SCR process. Reaction engineering aspects, such as the proper dosage of ammonia or urea, respectively, are as important as further developments of the different SCR catalysts, by deepening the understanding of their functionality or by systematic improvements of their properties, such as low-temperature activity, selectivity, or poisoning-resistance. Another covered aspect is cost reduction through the use of cheaper base materials for the production is active and stable SCR catalysts. Finally, research efforts are reported to develop SCR processes with different reducing agents, which would open doors to new applications in the future. The range of topics addressed in this book will stimulate the reader's interest as well as provide a valuable source of information for researchers in academia and industry.

This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of the U.S. Department of Energy (DOE) Clean Coal Technology (CCT) program is to furnish the energy marketplace with a number of advanced, more efficient, and environmentally responsible coal utilization technologies through demonstration projects. These projects seek to establish the commercial feasibility of the most promising advanced coal technologies that have developed beyond the proof-of-concept stage. This document serves as a DOE post-project assessment of a project selected in CCT Round 2. The project is described in the report ''Demonstration of Selective Catalytic Reduction (SCR) Technology for the Control of Nitrogen Oxide (NO(subscript x)) Emissions from High-Sulfur, Coal-Fired Boilers'' (Southern Company Services 1990). In June 1990, Southern Company Services (Southern) entered into a cooperative agreement to conduct the study. Southern was a cofunder and served as the host at Gulf Power Company's Plant Crist. Other participants and cofunders were EPRI (formerly the Electric Power Research Institute) and Ontario Hydro. DOE provided 40 percent of the total project cost of $23 million. The long-term operation phase of the demonstration was started in July 1993 and was completed in July 1995. This independent evaluation is based primarily on information from Southern's Final Report (Southern Company Services 1996). The SCR process consists of injecting ammonia (NH3) into boiler flue gas and passing the 3 flue gas through a catalyst bed where the NO(subscript x) and NH3 react to form nitrogen and water vapor. The objectives of the demonstration project were to investigate: Performance of a wide variety of SCR catalyst compositions, geometries, and manufacturing methods at typical U.S. high-sulfur coal-fired utility operating conditions; Catalyst resistance to poisoning by trace metal species present in U.S. coals but not present, or present at much lower concentrations, in fuels from other countries; and Effects on the balance-of-plant equipment from sulfur compounds formed by reactions between sulfur dioxide (SO2), sulfur trioxide (SO3), and NH3 (e.g., plugging and corrosion of downstream equipment). The Clean Air Act, initially promulgated in 1970, established New Source Performance Standards (NSPS) for emissions of SO2, NO(subscript x), and particulates, among other pollutants, from stationary coal-fired power plants. These regulations were made more stringent in the Clean Air Act Amendments (CAAA) of 1990. The SCR process is one way to meet the NO(subscript x) emissions requirements of the CAAA.

Book excerpt: This paper describes the status of the Innovative Clean Coal Technology project to demonstrate SCR technology for reduction of NO(subscript x) emissions from flue gas of utility boilers burning US high-sulfur coal. The funding participants are the US Department of Energy (DOE), Southern Company Services, Inc. (SCS), on behalf of the entire Southern Company, Electric Power Research Institute (EPRI), and Ontario Hydro. SCS is the participant responsible for managing all aspects of the project. The project is being conducted on Gulf Power Company's Plant Crist Unit 5 (75-MW nominal capacity), located near Pensacola, Florida, on US coals that have a sulfur content near 3.0%. The SCR facility treats a 17,400 scfm slip-stream of flue gas and consists of three 2.5-MW (5000 scfm) and six 0.2-MW (400 scfm) SCR reactors. The reactors operate in parallel with commercially available SCR catalysts obtained from vendors throughout the world. The design engineering and construction have been completed, and the startup/shakedown was completed in June 1993. Long-term performance testing began in July 1993 and will be conducted for two years. Test facility description and test plans, as well as start-up issues and preliminary commissioning test results are reported in this paper.
