  • 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: 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 In a first absorption stage solid precipitate of amine bicarbonate is formed and is withdrawn as slurry from the bottom of a first absorber section. In a second absorption stage solid precipitate of alkali metal bicarbonate is formed and withdrawn as slurry at the bottom of a second absorber section.

    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.

    Abstract: A granular sorption material including a plurality of porous granules formed by buildup agglomeration for separation, especially absorption, of harmful gases, especially of SOX and/or HCl, from offgases of thermal processes. The granules containing greater than 80% by weight, and preferably greater than 95% by weight, of Ca(OH)2 and/or CaCO3 based on the dry mass. The granules having a dry apparent density ?, determined by means of an apparent density pycnometer, of 0.5 to 1.2 kg/dm3, preferably 0.7 to 1.1 kg/dm3, and/or a porosity of 45% to 73% by volume, preferably 55% to 65% by volume, and have especially been increased in porosity. A process for producing the granular sorption material, in which pores are introduced into the granules by means of a porosity agent during the production.

  • Patent number: 9791106
    Abstract: A pretreatment system and method for a floating liquid natural gas (“FLNG”) facility are presented. The inlet natural gas stream flows through a membrane system to remove carbon dioxide and a heat exchanger, producing first and second cooled CO2-depleted non-permeate streams. The first cooled CO2-depleted non-permeate stream is routed to additional pretreatment equipment, while the second cooled CO2-depleted non-permeate stream is routed directly to a LNG train. Alternatively, the inlet natural gas stream may flow through a membrane system to produce a single cooled CO2-depleted non-permeate stream that is routed to the LNG train after sweetening and dehydration. Because the pretreatment system delivers the incoming gas stream to the LNG train at a lower temperature than conventional systems, less energy is needed to convert the gas stream to LNG. In addition, the pretreatment system has a smaller footprint than conventional pretreatment systems.

  • Patent number: 9750200
    Abstract: A flue gas treatment apparatus has a flue gas inlet, a treated gas outlet downstream of the flue gas inlet, and a gas flow path therebetween. The flue gas treatment apparatus comprises a particulate removal device. A first heater is downstream of the particulate removal device. The first heater heats the flue gas to a first treatment temperature. A first catalytic converter is downstream of the first heater for eliminating at least some CO and SO2 from the flue gas. A second heater is downstream of the first catalytic converter for heating the flue gas to a second treatment temperature. A second catalytic converter is downstream of the second heater for eliminating at least some NOx from the flue gas. At least a first fan forces the flue gas from the flue gas inlet to the treated gas outlet.

  • Patent number: 9670422
    Abstract: The invention relates to a process for removing and recovering mercury, an impurity, from a hydrocarbon feedstream containing oxygen, such as introduced during hydraulic fracturing. Mercury is selectively removed to very low levels of concentration from fluid streams such as natural gas, cracked gas, hydrogen or naphtha by passage of the stream through an adsorbent bed containing particles of a zeolitic molecular sieve preferably having pore diameters of at least 3.0 angstroms and in which the zeolite crystallites are formed into an aggregate (cylindrical or beads) which contain ionic or elemental silver. These adsorbent particles maintain their capacity for removal of mercury despite the presence of oxygen.
