Publication number: 20120288428Abstract: The disclosure provides methods and systems for sequestering and/or reducing sulfur oxides, nitrogen oxides and/or carbon dioxide present in industrial effluent fluid streams. A solid particulate material comprising a slag component, a binder component (distinct from the slag component), and optionally water is formed and then contacted with the effluent fluid stream to reduce at least one of the sulfur oxides, nitrogen oxides, and/or carbon dioxide. The contacting of the effluent stream may occur in a packed bed reactor with the solid dry particulate material. Methods of reducing pollutants from exhaust generated by combustion sources, lime and/or cement kilns, iron and/or steel furnaces, and the like are provided.Type: ApplicationFiled: July 27, 2012Publication date: November 15, 2012Applicant: C-QUEST TECHNOLOGIES L.L.C.Inventor: Douglas C. Comrie

Publication number: 20120272877Abstract: Sorbent components containing halogen, calcium, alumina, and silica are used in combination during coal combustion to produce environmental benefits. Sorbents such as calcium bromide are added to the coal ahead of combustion and other components are added into the flame or downstream of the flame, preferably at minimum temperatures to assure complete formation of the refractory structures that result in various advantages of the methods. When used together, the components reduce emissions of elemental and oxidized mercury; increase the level of Hg, As, Pb, and/or Cl in the coal ash; decrease the levels of leachable heavy metals (such as Hg) in the ash, preferably to levels below the detectable limits; and make a highly cementitious ash product.Type: ApplicationFiled: June 22, 2012Publication date: November 1, 2012Applicant: NOX II, LTD.Inventor: Douglas C.

Publication number: 20120174830Abstract: Methods involve adding sorbent components, such as calcium oxide, alumina, and silica, as well as optional halogens as part of environmental control. Use of the sorbents leads to significant reductions in sulfur and mercury emissions that otherwise would result from burning coal. Use of the sorbents leads to production of waste coal ash that, while higher in mercury; is nevertheless usable as a commercial product because the mercury in the ash is non-leaching and because the coal ash has a higher cementitious nature by virtue of the increased content of the sorbent components in the ash. Thus, the methods involve adding powders having qualities that lead to the production of a cementitious coal ash while at the same time reducing emissions from a coal burning facility.Type: ApplicationFiled: March 23, 2012Publication date: July 12, 2012Applicant: NOX II, LTD.Inventor: Douglas C.
