Acoustic agglomeration of power plant fly ash. Final report

Description: The work has shown that acoustic agglomeration at practical acoustic intensities and frequencies is technically and most likely economically viable. The following studies were performed with the listed results: The physics of acoustic agglomeration is complex particularly at the needed high acoustic intensities in the range of 150 to 160 dB and frequencies in the 2500 Hz range. The analytical model which we developed, although not including nonlinear acoustic efforts, agreed with the trends obs… more

Anion-exchange resin-based desulfurization process

Description: Under DOE Grant No. FG22-90PC90309, the University of Tennessee Space Institute (UTSI) is contracted to further develop its anion-exchange, resin-based desulfurization concept to desulfurize alkali metal sulfates. From environmental as well as economic viewpoints, it is necessary to remove soluble sulfates from the wastes created by flue gas desulfurization systems. In order to do this economically, a low-cost desulfurization process for spent sorbents is necessary. UTSI's anion-exchange resin-… more

Middle Fork and Upper Salmon River Habitat Improvement Implementation Plan, FY 1988-1992.

Description: This document presents an implementation plan for completing the phase II portion of the Middle Fork and Upper Salmon River Habitat Improvement Agreement. Underseeding of spawning adult salmon and steelhead, high instream sediment levels, a lack of habitat diversity in the form of overhanging riparian vegetation and edge, and barriers to both adult and juvenile anadromous fish migration were identified as the principal factors limiting anadromous fish production in the project area. Underseedin… more

Cross-flow, filter-sorbent catalyst for particulate, SO sub 2 and NO sub x control

Description: This report describes work performed on a new concept for integrated pollutant control: a cross-flow filter comprised of layered, gas permeable membranes that act as a particle filter, an SO {sub 2} sorbent, and a NO {sub x} reduction catalyst. One critical element of the R D program is the development of mixed metal oxide materials that serve as combined SO {sub 2} sorbents and NO {sub x} reduction catalysts. In this seventh quarterly progress report, we summarize the performance characteristi… more

A novel carbon-based process for flue gas cleanup

Description: 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% SO{sub 2} and at least 75% NO{sub 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 SO{sub 2} is oxidized to SO{sub 3} and removed as medium strength sulfuric acid. The … more

The 1990 Clean Air Act Amendments and the Great Lakes Economy: Challenges and Opportunities

Description: This paper deals with the market for SO{sub 2} emission allowances over time and electric utility compliance choices. For currently high emitting plants ( > 2.5 lb SO{sub 2}/MMBtu), the 1990 Clean Air Act Amendments (CAAA) provide for about twice as many SO{sub 2} allowances to be issued per year in Phase 1 (1995--1999) than in Phase 2. Also, considering the scrubber incentives in Phase 1, there is likely to be substantial emission banking for use in Phase 2. Allowance prices are expected to in… more
