  • Patent number: 10514371
    Abstract: Sampling devices for mercury speciation protocols are described. Devices can be utilized to separate mercury species from one another as a sample diffuses through a sampling device. Methods can determine the presence or quantity of targeted mercury species in a fluid sample. The devices are passive sampling devices based upon diffusion gradient in thin film (DGT) passive sampling devices. Devices include a reactant component and a sequesterant component that selectively react with a targeted species and retain a species (or a reaction product of a species) of a sample flow. Remaining mercury species can optionally be captured downgradient, for instance at an ion exchange resin.

  • Patent number: 10457598
    Abstract: A method of providing highly reactive hydrated lime and the resultant lime hydrate where an initial lime feed comprising calcium and impurities is first ground to a particle-size distribution with relatively course particles. Smaller particles are then removed from this ground lime and the smaller particles are hydrated and flash dried to form a hydrated lime, which is then milled to a significantly smaller particle size than that of the relatively course particles.

  • Patent number: 10434460
    Abstract: A class of water lean, organic solvents that can bind with various acid gasses to form acid gas bound molecules having a high degree of intramolecular hydrogen bonding which enables their use as regenerable solvents for acid gas capture. Unlike the other devices described in the prior art, the present invention takes advantage of shortened distances between the portions of the molecule that form hydrogen bonds within the structures when loaded with an acid gas so as to create a molecule with a higher internal bonding affinity and a reduced proclivity for agglomeration with other molecules.

  • Patent number: 10434501
    Abstract: The present invention belongs to the flue gas desulfuration field. Specifically, the present invention relates to a supported solid-phase catalyst for oxidizing the by-product magnesium sulfite in a magnesium desulfuration process, and to preparation method and use thereof. The catalyst uses an activated carbon particle as a support, and cobalt nitrate, manganese nitrate, copper nitrate and ferrous nitrate as catalytically active components. The preparation method is as follows: mixing the pre-treated activated carbon support with the catalytically active components, followed by oscillating, standing under microwave irradiation, filtrating, drying, baking, so as to obtain the supported solid-phase catalyst.

  • Patent number: 10419312
    Abstract: A process for improved real-time conflict identification and resolution, and information corroboration, during an interrogation relative to an incident includes capturing a first real-time digital audio or video stream from a first interviewee under interrogation by a first interviewer relative to an incident. The first real-time digital audio or video stream is converted to a first digital text string, which is then semantically processed to identify and store first information relative to the incident. Stored second information created via interrogation of a second interviewee under interrogation relative to the incident is accessed, and a conflict between the stored first information and the stored second information is identified. A visual or audio prompt is generated associated with the conflict and an indication of the conflict is played back via the visual or audio prompt to the first interviewer.

  • Patent number: 10413860
    Abstract: The present invention relates to an absorbent, an absorbent system and a process for removing acidic gas such as CO2 from exhaust gases from fossil fuel fired power stations, from natural gas streams, from blast furnace oven off-gases in iron/steel plants, from cement plant exhaust gas and from reformer gases containing CO2 in mixtures with H2S and COS. The liquid absorbent, a mixture of amine and amino acid salt is contacted with a CO2 containing gas in an absorber and CO2 in the gas stream is absorbed into the liquid. The absorbed CO2 forms more than one type of solid precipitate in the liquid at different absorption stages. In a first absorption stage solid precipitate of amine bicarbonate is formed and is withdrawn as slurry from the bottom of a first absorber section. In a second absorption stage solid precipitate of alkali metal bicarbonate is formed and withdrawn as slurry at the bottom of a second absorber section.

  • Patent number: 10399002
    Abstract: A method for separating lighter components of a hydrocarbon product in a container tank includes introducing the hydrocarbon product into the container tank via an inlet located near or at the bottom of the container tank; routing the hydrocarbon product through a pipe-in-pipe conduit that is at least partially surrounded by a bulk fluid stored in the container tank; providing a vapor-liquid interface that allows efficient evaporation of the lighter components resulting in separation of the lighter components and a processed hydrocarbon product; and routing the processed hydrocarbon product into the annular space of the pipe-in-pipe conduit thereby thermally insulating incoming hydrocarbon product from the surrounding bulk fluid and eliminating or minimizing vapor liquid equilibrium shift of the incoming hydrocarbon product caused by increased head pressure and/or reduction in temperature of the incoming hydrocarbon product.
