This book was released on 1992 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project is to demonstrate the preliminary technical and economic feasibility of a novel carbon-based process for removal of at least 95% SO2 and at least 75% NO(subscript x) from coal combustion flue gas. In the process, flue gas leaving the electrostatic precipitator (ESP) is passed through a trickle bed of activated carbon catalyst employing a periodic flush of low strength sulfuric acid. The SO2 is oxidized to SO3 and removed as medium strength sulfuric acid. The SO2-free flue gas is then mixed with NH3, and the NO(subscript x) in the gas is subjected to selective catalytic reduction (SCR) to N2 over a fixed-bed of activated carbon catalyst.

Book excerpt: The objective of this project is to demonstrate the preliminary technical and economic feasibility of a novel carbon-based process for removal of at least 95% SO2 and at least 75% NO(subscript x) coal combustion flue gas. In the process, flue gas leaving the electrostatic precipitator (ESP) is passed through a trickle bed of achieved carbon catalyst employing a periodic flush of low strength sulfuric acid. The SO2 is oxidized to SO3 and removed as medium strength sulfuric acid. The SO2-free flue gas is then mixed with NH3, and the NO(subscript x) in the gas is subjected to selective catalytic reduction (SCR) to N2 over a fixed bed of activated carbon catalyst. The experimental work is divided between Research Triangle Institute (RTI) and the University of Waterloo (Waterloo). RTI will conduct the NO(subscript x) removal studies, whereas Waterloo will conduct the SO2 removal studies. The ultimate goal of the project is to demonstrate that the process can be reduce the cost of electricity by 20% over conventional SCR/flue gas desulfurization (FGD) processes. In the present quarter, the continuous SO2 analyzer system at Waterloo was completed. The SO2 removal factorial experiments were begun Waterloo with the BPL carbon at 21°C. Also, SO2 removal was tested on two catalyst at RTI at 80°C. NO(subscript x) conversion was tested on a variety of catalysts at RTI. It was shown that the BPL carbon could remove over 95% SO2 at 21°C but would required several beds at space velocity in each bed of abut 1,500 scc/(cc·h) to reduce SO2 from 2,500 ppm to 100 ppm. A modified carbon catalyst tested at RTI showed 99% SO2 removal at 80°C at 1,400 scc/(cc·h). Also, it was possible to produce nearly 9 normal H2SO4 by periodic flushing of this catalyst. The modified carbon catalyst also demonstrated removal of more than 80% NO(subscript x). 7 refs., 7 figs., 4 tabs.

Book excerpt: The objective of this project is to demonstrate the preliminary technical and economic feasibility of a novel carbon-based process for removal of at least 95 % SO2, and at least 75 % NO(subscript x) from coal combustion flue gas. In the process, flue gas leaving the electrostatic precipitator (ESP) is passed through a trickle bed of activated carbon catalyst employing a periodic flush of low strength sulfuric acid. The SO2 is oxidized to SO3 and removed as medium strength sulfuric acid. The SO2-free flue gas is then mixed with NH3, and the NO(subscript x) in the gas is subjected to selective catalytic reduction (SCR) to N2 over a fixed bed of activated carbon catalyst. In the previous six quarters, detailed project plans were prepared and experimental systems were commissioned. The SO2 removal factorial experiments with BPL carbon at 21°C are well underway at Waterloo. A modified carbon catalyst (MCCI) showed up to 99% SO2 removal in the presence of NO(subscript x) over 10 multiple cycles at 80--130°C and 1400 scc/cc/h. Several catalysts were evaluated for NO(subscript x) removal also. Promising modified carbon catalysts (MCCI, II and III) were tested. Some of these catalysts showed the potentialfor over 80% NO(subscript x) removal at space velocities as high as 3000 scc/cc/h. Poisoning of NO(subscript x) removal efficiency with SO2 in the feed was also studied. With over 100 ppm SO2 in feed, NO(subscript x)removal efficiency remained steady for several hours. It declined from 79% removal to 66% removal over 24 hours. NO(subscript x) removal experiments were performed with 5 different materials and the SO2 removalactivity of 2 catalysts was tested.

In the present quarter, a detailed project management plan was prepared describing the experimental set-up, work plan and test plan. The experimental equipment is being constructed and is nearly complete with shakedown experiments scheduled to begin on or about November 1, 1991. Also, a paper was prepared and presented for the Seventh Annual Contractor's Conference. The first set of experiments will be completed in the next quarter. 7 refs., 5 figs., 4 tabs.

This book was released on 1992 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project is to demonstrate the preliminary technical and economic feasibility of a novel carbon-based process for removal of at least 95% S02 and at least 75 % NO(subscript x), from coal combustion flue gas. In the process, flue gas leaving the electrostatic precipitator (ESP) is passed through a trickle bed of activated carbon catalyst employing a periodic flush of low strength sulfuric acid. The S02 is oxidized to S03 and removed as medium strength sulfuric acid. The S02-free flue gas is then mixed with NH3, and the NO(subscript x) in the gas is subjected to selective catalytic reduction (SCR) to N2 over a fixed bed of activated carbon catalyst. In the previous four quarters, a detailed project management plan was prepared describing the experimental setup, work plan, and test plan. The experimental system was completed for SO2 conversion at Waterloo and for NO(subscript x) conversion at Research Triangle Institute. Shakedown experiments were completed. The NO(subscript x) removal performance of two additional modified carbon catalysts (MCCII and MCCIII) was studied. MCCII showed NO2 removal efficiency which was similar to that observed for MCCI. However, MCCIII was considerably less active for NO(subscript x) removal. In the present quarter, further tests of MCCI were performed for SO2 removal with NO in the feed gas, except the reactor was operated at 130°C (instead of 80°C during previous tests). Tests were also performed with MCCII for NO removal with nominally 100 ppm SO2 in the feed gas.

The SO2-free flue gas is then mixed with NH3, and the NO(subscript x) in the gas is subjected to selective catalytic reduction (SCR) to N2 over a fixed bed of activated carbon catalyst. In the previous three quarters, a detailed project management plan was prepared describing the experimental setup, work plan, and test plan. The experimental system was completed for SO2 conversion at Waterloo and for NO(subscript x) conversion at RTI. Shakedown experiments were completed. In the present quarter, the NO(subscript x) removal performance of two additional modified carbon catalysts (MCCII and MCCIII) was studied. MCCII showed NO(subscript x) removal efficiency which was similar to that observed for MCCI. However, MCCI was considerably less active for NO(subscript x) removal. SO2 removal experiments with NO present in the feed gas were performed with MCCI. SO2 removal efficiency was consistently about 98% over each of 10 cycles and was very similar to that observed earlier with no NO present in the feed. Finally, a preliminary economic evaluation of the process was performed and a project review meeting was held. The economic evaluation showed that the Rn-Waterloo process was competitive with SCR/IFGD and other combined SO2/NO(subscript x), removal processes.

Available in PDF, EPUB and Kindle. Book excerpt: A low-temperature process employing activated carbon-based catalysts and operating downstream of the electrostatic precipitator (ESP) was evaluated jointly by Research Triangle Institute (RTI) and the University of Waterloo (Waterloo). The RTI-Waterloo process was projected to be capable of removing more than 95% SO[sub 2] and 75% NO[sub x]from coal combustion flue gas. In the process, the flue gas leaving the ESP is first cooled to approximately 100[degree]C. The SO[sub 2] is then catalytically oxidized to SO[sub 3] which is removed as medium-strength sulfuric acid in a series of periodically flushed trickle-bed reactors containing an activated carbon-based catalyst. The SO[sub 2]-free gas is then reheated to approximately 150[degree]C and NH[sub 3] is injected into the gas stream. It is then passed over a fixed bed of another activated carbon-based catalyst to reduce the NO[sub x] to N[sub 2] and H[sub 2]O. The clean flue gas is then vented to the stack. The feasibility of the process has been demonstrated in laboratory-scale experiments using simulated flue gas. Catalysts have been identified that gave the required performance for SO[sub 2] and NO[sub x] removal with

Quarterly Technical Progress Report No. 4, December 1, 1991--February 29, 1992 written by and published by . This book was released on 1992 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NOXSO Process is a dry, post-combustion flue gas treatment technology which uses a regenerable sorbent to simultaneously adsorb sulfur dioxide (SO2) and nitrogen oxides (NOx) from the flue gas of a coal-fired utility boiler. In the process, the SO2 is reduced to elemental sulfur and the NOx is reduced to nitrogen and oxygen. It is predicted that the process can economically remove 90% of the acid rain precursor gases from the flue gas stream in a retrofit or new facility. The objective of the NOXSO Demonstration Project is to design, construct, and operate a flue gas treatment system utilizing the NOXSO Process at Ohio Edisons̀ Niles Plant Unit {number_sign}1. The effectiveness of the process will be demonstrated by achieving significant reductions in emissions of sulfur and nitrogen oxides. In addition, sufficient operating data will be obtained to confirm the process economics and provide a basis to guarantee performance on a commercial scale. Ohio Edisons̀ Niles Plant Unit {number_sign}1 generates 115 MW of electricity and 275,000 scfm of flue gas while burning 3.5% sulfur coal. The project is presently in the project definition and preliminary design phase. This phase was included in the project to allow completion of process studies and preliminary activities which could be conducted in parallel with NOXSOs̀ pilot plant project being conducted at Ohio Edisons̀ Toronto Power Plant.

This book was released on 1992 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have used non-aqueous impregnation techniques to prepare an aluminum oxide surface covered with a well-dispersed magnesium oxide layer using magnesium acetylacetonate dehydrate [Mg(acac)2{sm_bullet}2H20] as a precursor. Using lithium acetylacetonate as a precursor, we have begun attempts to prepare a similarly well dispersed surface layer of lithium ''oxide.'' We have generated higher weight loadings of magnesium on alumina by using a Soxhlet extractor to dissolve the sparingly soluble Mg(acac)2{sm_bullet}2H20 in methanol. With this device we are able to obtain loadings of MgO on the alumina up to 0.66 wt/wt%. The precursor samples were examined by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and our results indicate that the complex loses the water of hydration upon adsorption. It appears, however, that the initial form of the complex on the surface is as anhydrous crystallites. Heating the supported precursor under vacuum leads to ''melting'' of the crystals, which can be observed by DRIFTS. Decomposition of the precursor under nitrogen or air leads to very similar activity when adsorbing SO2. SO2 uptake appears to be independent of whether O2 is Present in the gas stream or not. We have shown that SO2 adsorption increases with Mg-loading on the impregnated aluminas, with 0.85 additional molecules Of SO2 adsorbed for each additional Mg atom (or MgO molecule) on the surface. We have shown that non-aqueous impregnation leads to samples which are more efficient with regard to SO2 uptake per magnesium atom than aqueous impregnation.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The CZD process involves injecting a finely atomized slurry of reactive lime into the flue gas duct work of a coal-fired utility boiler. The principle of the confined zone is to form a wet zone of slurry droplets in the middle of the duct confined in an envelope of hot gas between the wet zone and the duct walls. The lime slurry reacts with part of the SO[sub 2] in the gas, and the reaction products dry to form solid particles. A solids collector, typically an electrostatic precipitator (ESP) downstream from the point of injection, captures the reaction products along with the fly ash entrained in the flue gas. The goal of this demonstration is to prove the technical and economic feasibility of the CZD technology on a commercial scale. The process is expected to achieve 50% SO[sub 2] removal at lower capital and O & M costs than other systems. To achieve its objectives, the project is divided into the following three phases: Phase 1: Design and Permitting, Phase 2: Construction and Start-up, Phase 3: Operation and Disposition. Phase 1 activities were completed on January 31, 1991. Phase 2 activities were essentially concluded on July 31, 1991, and Phase 3a, Parametric Testing, was initiated on July 1, 1991. This Quarterly Technical Progress Report covers Phase 3b activities from August 17, 1992 through November 16, 1992.
