Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project is to study the fundamental nature of the sorbent reactivity and reaction kinetics in the medium temperature range from 600 to 1200[degrees]F available in the convective pass of a boiler upstream of the economizer, where dry sorbents and anhydrous ammonia are injected to reduce SO[sub 2], and NO[sub 2], from the flue gas. The following conclusions are drawn from the results of the third year of study. The dehydration conversion increased with reaction temperature from 3% at 600[degrees]F to 36% at 1100[degrees]F. The fresh CaO from the dehydration reaction of Ca(OH)[sub 2] is very active in air. The carbonation conversion increases slightly with residence time from 50ms to 75ms. In the simultaneous carbonation/sulfation reaction the carbonation conversion increased continuously with the reaction temperature from 600[degrees]F to 1100[degrees]F. By comparing the sulfation conversion of Ca(OH)[sub 2] and CaO at 900[degrees]F and residence times from 50 to 75ms, it is found that the sulfation conversion of CaO at this temperature range was significant and could not be ignored. The carbonation reaction took place simultaneously with sulfation reaction under the fixed bed and drop-tube reactor conditions.

Download or read book Flue Gas Desulfurization and Industrial Minerals written by M. Michael Miller and published by . This book was released on 1993 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contains 4,101 references on FGD [Flue Gas Desulfurization] ... primarily from 1982 through June 1993. Complements the "Flue Gas Desulfurization and Denitrification" bibliography published by the U.S. Dept. of Energy in Jan. 1985. References were located on the Energy, Science and Technology, Pollution Abstracts, and Environmental Bibliography databases. Primarily covers FGD and the use of industrial minerals in the desulfurization process or in by-product utilization and disposal. Emphasizes post-combustion removal of sulfur dioxide through processes such as in-duct injection and wet and dry scrubbing.

Download or read book Kinetics and Structural Evolution of Sorbents at High Temperatures. Final Report, September 1, 1992--August 31, 1993 written by and published by . This book was released on 1993 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this project is on furnace sorbent injection technology using dry, calcium-based sorbents for flue gas desulfurization. The goal is to provide fundamental research kinetics and the effects of sorbent properties, aimed at improving SO2 removal and increasing sorbent utilization in a cost-effective fashion. The main focus of the third year work has been to obtain fundamental kinetic data for calcination, sintering and sulfation of calcium hydroxide sorbent. The results, their interpretation, and discussions are the primary focus of this report. Other major portions of this year's work covered in the report include the additions and modifications made to the experimental system, and preliminary results of the studies with modified Ca(OH)2. Most of the reactor system and the analytical and measurement techniques were developed in the second year and formed the necessary framework for realizing the project goal. A few design and experimental constraints necessitated modifications and additions which were made in the beginning of this year. A continuous micro-feeder was built in order to feed very small quantities of sorbent, which is essential to maintain differential conditions with respect to SO2 during sulfation experiments. The particle collection probe was modified with an insulating ceramic cover and cap, in order to reduce its cooling effect and achieve better isothermality within the reactor. A cascade cyclone sampler was added to replace the impactor because the particle loading capacity of the impactor was not sufficient to hold enough powder required for post-reaction analyses.

This book was released on 1989 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of Ontario Hydro's Acid Gas Control Program, furnace sorbent injection (FSI or LIF) is a candidate technology now considered for installation to control acid gas emissions from thermal generating stations. Furnace injection is a commercially unproven process in which the sorbent (limestone or hydrated lime) is injected directly into the furnace of a coal-fired boiler. The FSI reaction by-products, consisting of fly ash, sulphation by-products and unreacted sorbent, is subsequently removed from the flue gas stream using fabric filters or electrostatic precipitators located downstream of the boiler. The volume of FSI by-product is significantly more than from other flue gas desulphurization processes. This report presents the results of a study to determine the engineering/physical properties of FSI waste.

This book was released on 1996 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this project is on furnace sorbent injection technology using dry calcium-based sorbents for the flue gas desulfurization. The goal is to provide fundamental research kinetics and effects of sorbent properties, aimed at improving SO2 removal and increasing sorbent utilization in a cost-effective manner. The fifth year project work has been carried out in two phases: (1) modified sorbent studies to understand the influence of sorbent modifications (both physical and chemical) on reaction mechanisms, and (2) development of a comprehensive sulfation model to interpret and predict short-time simultaneous calcination, sulfation and sintering processes. This report discusses these two phases of research.

Available in PDF, EPUB and Kindle. Book excerpt: Results of a benchscale study of the effect of in-duct humidification of furnace-injected limestone-based sorbents on additional SO2 removal. Four levels of relative humidity (0, 27, 56, and 77% RH at 70C), and temperatures ranging from 80-1000C were studied. Testing was done on Beachville and Pt. Anne high calcium limestones, King dolomitic limestone, and Beachville hydrated lime. The partially sulfate sorbents were generated using the benchscale quartz flow-through reactor and exposed to a humidified synthetic flue gas stream in the Thermal Gravimetric Analyzer.
