  • Patent number: 8992868
    Abstract: Dry processes, apparatus, compositions and systems are provided for reducing emissions of mercury and optionally sulfur oxides and/or HCl. In an embodiment the copper-based mercury remediation composition comprises a copper ammonium complex having an empirical formula of C2H7CuNO2 or any of the other materials described, which include compositions defined by the formula Cu(NH3)x(lower carboxylate)y, wherein the lower carboxylate is selected from the group consisting of formate, acetate and propionate, x is an integer from 0 to 4, y is an integer from 0 to 2, and x+y is equal to or greater than 1. Sulfur oxides and/or HCl can be additionally reduced by introduction of dolomite hydrate sorbent, and additional mercury remediation chemicals as manganese oxides can be employed. The treated gas stream is treated with a particulate removal device.

  • Patent number: 8916120
    Abstract: Dry processes, apparatus, compositions and systems are provided for reducing emissions of sulfur oxides, and sulfur dioxide in particular, and/or HCl in a process employing a combination of a dolomite hydrate sorbent and a sorbent doping agent administered to achieve coverage of a three-dimensional cross section of a passage carrying SOx and/or HCl —containing gases with a short but effective residence time at a temperature effective to provide significant sulfur dioxide and/or HCl reductions with high rates of reaction and sorbent utilization. The once-through, dry process can advantageously introduce the sorbent and sorbent doping agent dry or preferably as a slurry to enable uniform treatment. Preferred sorbent doping agents include water-soluble or water-dispersible copper and/or iron compositions which can be heated to an active form in situ by the flue gases being treated.

  • Publication number: 20070210005
    Abstract: It has been found that phosphorous-containing and oxyanion compounds can be removed efficiently and economically by adsorption with cation-exchanged aluminosilicates that are ion-exchanged in a concentrated aluminosilicate composition containing the aluminosilicate, the exchange cations, and only about 15% to about 50% by weight water, based on the total weight of the aluminosilicate and water. Further, the ion-exchange process described herein has been found to be effective, in addition to those complexing or ion-exchange elements described in the Douglas '383 patent, when complexed or ion-exchanged with one or more elements of Group VIII (Fe, Co, Mi, Ru, Rh, Pd, Re, Os, Ir), Group IB (Cn, Ag, Au), and Group IIB (Zn, Cl, Hg).

  • Patent number: 7267784
    Abstract: Compositions and methods for planarizing or polishing a surface, particularly a semiconductor wafer surface. The polishing compositions described herein comprise (a) a liquid carrier; (b) purified clay; and optional additives, such as (c) a chemical accelerator; and (d) a complexing or coupling agent capable of chemically or ionically complexing with, or coupling to, the metal and/or insulating material removed during the polishing process. The complexing or coupling agent carries away the removed metal and/or silicon dioxide insulator particles, during polishing, to prevent the separated particles from returning to the surface from which they were removed. Also disclosed are methods of planarizing or polishing a surface comprising contacting the surface with the compositions.
