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% SO2 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°C. The SO2 is then catalytically oxidized to SO3 which is removed as medium-strength sulfuric acid in a series of periodically flushed trickle-bed reactors containing an activated carbon-based catalyst. The SO2-free gas is then reheated to approximately 150°C and NH3 is injected into the gas stream. It is then passed over a fixed bed of another activated carbon-based catalyst to reduce the NOx to N2 and H2O. 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 SO2 and NOx removal with

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.

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) 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 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.

This book was released on 1993 with total page 46 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. 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.

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.
