  • Effects on Bromine, Chlorine and SO2 Under Air Firing and Oxy-Fuel
    GAS-PHASE MERCURY OXIDATION: EFFECTS OF BROMINE, CHLORINE AND SO2 UNDER AIR FIRING AND OXY-FUEL CONDITIONS, EXPERIMENTAL AND MODELING STUDY by Paula Andrea Buitrago A dissertation submitted to the faculty of The University of Utah in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Chemical Engineering The University of Utah August 2011 Copyright © Paula Andrea Buitrago 2011 All Rights Reserved STATEMENT OF DISSERTATION APPROVAL The dissertation of Paula Andrea Bnitrago has been approved by the following supervisory committee members: Geoffrey D.

Wight, Dean of The Graduate School. ABSTRACT The mercury in coal is emitted in its elemental state when the coal is burned. As the combustion flue gas cools, reactions under homogeneous and heterogeneous conditions between mercury and species such chlorine, bromine, SOx and NOx can take place. The temperature and concentration of these species determines the extent of mercury oxidation. The main objective of this study was to evaluate the effects of bromine, chlorine, SOx and NOx on gas-phase mercury oxidation reactions in flue gas. This study used a methane-fired, bench-scale reactor and CHEMKIN software for performing kinetic calculations. The model included reaction pathways to account for halogen, mercury, and combustion chemistry. The experimental results showed that chlorine is not effective as a gas-phase oxidant of mercury compared with other halogens such as bromine.

Infobox links nitrogen tribromid is a chemical compound with the NBr3 formula. It is extremely explosive in its purest form, even at 100 degrees Celsius, and was not isolated until 1975. It's deep-red and volatile solid. The drug NBr3 was first prepared by the reaction of bistrimetligrilbramamin (bis (trimethylsil)amin bromide) with bromine monochloride (with trimethylylyl chloride as a by-product) at 87 degrees on the following equations: (Me3Si)2NBr2 BrCl → NBr3 and 2 Me3SiCl, Where Me is He instantly reacts with ammonia in a dichloromethane solution at 87 degrees Celsius to give NBrH2.
