Theoretical approach for enhanced mass transfer effects in-duct flue gas desulfurization processes

Description: Removal of sulfur dioxide (SO{sub 2}) from the flue gas of coal- burning power plants can be achieved by duct spray drying using calcium hydroxide (Ca(OH){sub 2}) slurries. A primary objective of this research was to discover the aspects of mass transfer into Ca(OH){sub 2} slurries which limit SO{sub 2} absorption. A bench- scale stirred tank reactor with a flat gas/liquid interface was used to simulate SO{sub 2} absorption in a slurry droplet. The absorption rate of SO{sub 2} from gas concentr… more

Theoretical approach for enhanced mass transfer effects in-duct flue gas desulfurization processes

Description: This report presents the results of fundamental mass transfer testing for in-duct removal of SO{sub 2}. Following this initial part of an experimental program, it became clear that the amount of initial moisture on the sorbent strongly affected the extent of Ca(OH){sub 2} conversion. Novel techniques aimed at increasing sorbent utilization were investigated and are described. Major novel technique investigated and reported on here was the reaction with SO{sub 2} of sorbents with initial free mo… more

Organic evaporator steam valve failure

Description: Defense Waste Processing Facility (DWPF) Technical has requested an analysis of the capacity of the Organic Evaporator (OE) condenser (OEC) be performed to determine its capability in the case where the OE steam flow control valve fails open. Calculations of the OE boilup and the OEC heat transfer coefficient indicate the OEC will have more than enough capacity to remove the heat at maximum OE boilup. In fact, the Salt Cell Vent Condenser (SCVC) should also have sufficient capacity to handle th… more

Investigation of cold nuclear fusion in condensed matter. Final report

Description: Recent research has been directed towards finding means to produce neutron emissions at will, to demonstrate reproducibility, and to permit in-depth studies of the origin of neutron emissions. this goal has been pursued in the Kamiokande detector in Japan and has led to the development of a deep underground laboratory in a tunnel in the Wasatch mountains near Brigham Young University. New counters for low-level neutron emissions are being utilized. Calorimetric tools have also been developed.

Applications of Micellar Enzymology to Clean Coal Technology. Tenth Quarterly Report

Description: Full implementation of coal fuel sources will require more effective methods of providing ``clean coal`` as a fuel source. Methods must be developed to reduce the sulfur content of coal which significantly contributes to environmental pollution. This project is designed to develop methods for pre-combustion coal remediation by implementing recent advances in enzyme biochemistry. The novel approach of this study is incorporation of hydrophilic oxidative enzymes in reverse micelles in an organic … more
