  • Patent number: 9260669
    Abstract: The use of neutral aqueous solutions of glyoxal (pH approximately 6 to 8.5) scavenges H2S that is present in natural gas and in oil better than glyoxal alone or base alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over glyoxal used alone. A buffer may be optionally used. In another embodiment, the combination of non-nitrogen-containing surfactants and glyoxal results in a significant increase in the reaction rate and the overall scavenging efficiency, i.e. capacity as compared to glyoxal used alone.

  • Patent number: 8961821
    Abstract: A process of treating a gas stream containing mercury and acid gas pollutants is disclosed. The process includes applying a sorbent composition into a gas stream in order to adsorb mercury containing compounds and acid gas pollutants. The sorbent composition includes a compound having the formula (SiO2)x(OH)yMzSaF.B. The combination of basic inorganic solids for the adsorption of acid gases, and metal sulfide-doped silica for the adsorption of mercury provides dual sorbent functionality, along with additional benefits for each individual sorbent: silica for moisture retention on the surface of the basic inorganic particle and adsorption of acid gas, which will improve metal sulfide performance at higher operating temperatures. The use of a hygroscopic solid effectively dries the metal sulfide-doped silica slurry without the use of filtration of drying equipment, providing significant economic benefit for the manufacture of metal sulfide-doped silica material.

  • Publication number: 20140312271
    Abstract: Method for the production of a clay-alkali-amine CO2 sorbent prepared by integrating a clay substrate, basic alkali salt, and amine liquid. The basic alkali salt is present relative to the clay substrate in a weight ratio of from about 1 part to about 50 parts per 100 parts of the clay substrate. The amine liquid is present relative to a clay-alkali combination in a weight ratio of from about 1 part to about 10 parts per 10 parts of the clay-alkali combination. The clay substrate and basic alkali salt may be combined in a solid-solid heterogeneous mixture and followed by introduction of the amine liquid. Alternatively, an alkaline solution may be blended with the amine solution prior to contacting the clay substrate. The clay-alkali-amine CO2 sorbent is particularly advantageous for low temperature CO2 removal cycles in a gas stream having a CO2 concentration less than around 2000 ppm and an oxygen concentration around 21%, such as air.

    Abstract: Provided is an absorbent for capturing carbon dioxide. The absorbent may include an amino acid with multiple amine groups and an alkali-metal hydroxide mixed with the amino acid and thus, may increase an absorption capacity for carbon dioxide. When a sterically hindered effect is induced to the amino acid with multiple amine groups, the absorption capacity for carbon dioxide may increase and heat of absorption reaction may decrease and thus, energy consumed for regeneration of an absorbent may be reduced. The absorbent for capturing carbon dioxide may include amino acid with multiple amine groups and the metal hydroxide, and may provide a functional group around the amine groups to cause an sterically hindered effect and thus, the absorption capacity for carbon dioxide and an carbon dioxide absorption rate may increase, and the capital cost for a carbon dioxide capturing process and an operating cost may be significantly reduced.

  • Patent number: 7435380
    Abstract: A pseudo-plastic or thixotropic carrier having anti-malodorous components dissolved or suspended therein is sprayed on the internal surfaces of an ostomy bag or pouch. The viscoelastic properties of the carrier allow the composition to be conveniently dispensed from a spray bottle into the ostomy bag and retained on the inner walls thereof without being displaced therefrom by incoming waste during use of the ostomy bag. This allows the composition to continue to deodorize the ostomy bag headspace even after waste material begins to fill the bag.

  • Patent number: 6399036
    Abstract: The present invention relates generally to the use of a combination of alkali metal hydroxides and alkaline-earth metal hydroxides as a scavenging material for cyanide gas. In particular, the present invention relates to a method and means for either filtering out cyanide gas or detoxifying areas contaminated with cyanide using Sodalime or Baralyme™. The scavenging material of the invention is typically incorporated into a scrubbing device wherein a motor (50) powers a fan (52) to draw contaminated air into an inlet (54) and across a filter (56) which contains the scavenger material, thereby absorbing cyanide gas contained in the air.
