  • COAL DUST TREATMENT METHODS AND COMPOSITIONS
    Publication number: 20180346834
    Abstract: Methods and compositions for treating coal are provided. A nitroxyl radical compound is added to the coal in order to inhibit coal autooxidation. Additionally, the nitroxyl radical compound can be conjointly used with conventional dust control agents, in order to suppress fugitive coal dust dissemination. In those cases in which foamed treatment is desired to treat coal dust, the nitroxyl radical compound can be conjointly used in the foamable compositions, along with a variety of foam building surfactants such as the amphoteric, nonionic and anionic surfactants.

  • ADSORBENT COMPOSITION BY A GREEN PROCESS AND A PROCESS FOR TOXIC METAL ION REMOVAL
    Publication number: 20140116949
    Abstract: An adsorbent composition of a carrier coated with nanoparticles of zerovalent iron (“NZVI”) is disclosed. The NZVI are synthesized in situ using a tannin extract. Methods of making the adsorbent composition comprise providing a liquid stream; dispersing iron salts in the liquid stream to form an iron salt solution; adding a carrier to the iron salt solution to form a prepared stream; adding a tannin extract to the prepared stream to form a reaction stream; and forming the adsorbent composition in the reaction stream. Methods of reducing toxic metal ions in an aqueous stream are also disclosed. The methods comprise providing said aqueous stream; providing an adsorbent composition having a carrier coated with in situ nanoparticles of zerovalent iron (“NZVI”) therein; and contacting the aqueous stream with the adsorbent composition.

  • METHODS FOR BREAKING CRUDE OIL AND WATER EMULSIONS
    Publication number: 20090197978
    Abstract: A method for breaking a crude oil emulsion includes treating the emulsion at an elevated temperature with a demulsifier. The demulsifier contains at least 70 percent by weight of ethylene oxide, 3-hydroxypropylene oxide, or a mixture and has a cloud point temperature of at least about 100° C. A method for desalting the crude oil is also provided.
