  • Patent number: 8679228
    Abstract: The invention recovers highly pure hydrogen from the exhaust purge gas and reuses it as a hydrogen source in other production steps contributing to greatly reducing the disposal cost and the cost of producing polysilicon. The hydrogen chloride contained in the exhaust gas discharged from the step of depositing polysilicon by using trichlorosilane, is adsorbed by active carbon. The active carbon layer is then purged with the hydrogen gas, and the adsorbed hydrogen chloride is desorbed. Next, the exhaust purge gas is brought into contact with a hydrogen chloride-absorbing solution such as an aqueous solution of sodium hydroxide to remove the hydrogen chloride from the exhaust purge gas and to separate and recover the highly pure hydrogen gas. The recovered hydrogen gas is compressed and is fed as a hydrogen source to other steps of producing, for example, fumed silica.

  • Patent number: 8449652
    Abstract: Polymerizable ionic liquid monomers and their corresponding polymers (poly(ionic liquid)s) are created and found to exhibit high CO2 sorption. The poly(ionic liquid)s have enhanced and reproducible CO2 sorption capacities and sorption/desorption rates relative to room-temperature ionic liquids. Furthermore, these materials exhibit selectivity relative to other gases such as nitrogen, methane, and oxygen. They are useful as efficient separation agents, such sorbents and membranes. Novel radical and condensation polymerization approaches are used in the preparation of the poly(ionic liquids).

  • Publication number: 20130123560
    Abstract: Crystals of [VOBDC](H2BDC)0.71 were synthesized hydrothemally. The guest acid molecules were removed by heating in air to give high quality single crystals of VOBDC. VOBDC was observed to show crystal-to-crystal transformations on absorption of the guest molecules aniline, thiophene and acetone from the liquid phase. Accurate structural data of the guest molecules and framework deformations were obtained from single crystal X-ray data. VOBDC was also shown to absorb selectively thiophene and dimethyl sulphide from methane.

  • Publication number: 20130081538
    Abstract: A moisture removal system for removing water moisture from an air stream and an associated method are provided. The moisture removal system includes one or more packed beds that include a water-entry surface at which liquid water is received and an air-entry surface that is located substantially opposite the water-entry surface and at which the air stream is received. The air stream passes through the one or more packed beds in a direction substantially counter-current to the passage of the liquid water and the liquid water and the air stream contact one another in the one or more packed beds resulting in the removal of at least a portion of the water moisture from the air stream. The moisture removal system can be located upstream of and be operably connected to the inlet of a gas turbine system to which the air stream is delivered from the moisture removal system.

  • Publication number: 20130055893
    Abstract: A chamber air scrubber a chamber with an independent air scrubbing system for configured to adsorb plant odors and emissions. The scrubber includes air scrubbers for cleaning the air. The air scrubbers include a carbon portion with active carbon that adsorbs odors and emissions. The carbon portion includes an outer and an inner cylindrical frame that retain active carbon between them. The air scrubbers also include a series of fans that forces air through the carbon portion. The fans allow the air to pass from a lower chamber to an upper chamber. The air enters through an inlet in the lower chamber before passing over a liquid chiller. The air transfers the thermal energy generated by the plants to a vent in the upper chamber. This serves to eliminate odor from the plants.

  • Patent number: 8337589
    Abstract: A method and apparatus for extracting CO2 from air comprising an anion exchange material formed in a matrix exposed to a flow of the air, and for delivering that extracted CO2 to controlled environments. The present invention contemplates the extraction of CO2 from air using conventional extraction methods or by using one of the extraction methods disclosed; e.g., humidity swing or electro dialysis. The present invention also provides delivery of the CO2 to greenhouses where increased levels of CO2 will improve conditions for growth. Alternatively, the CO2 is fed to an algae culture.

  • Patent number: 8328910
    Abstract: A method of remediating at least a portion of a building that contains defective drywall is presented. The method comprises removal of the defective drywall and cross-contaminated drywall, actively desorbing volatile compounds from the building materials exposed after removal of the drywall and passively desorbing remaining contaminants by depositing a film of an absorbent on the accessible surfaces of the exposed building materials. Active desorbing of volatiles can be carried out with forced thermal desorption, where the interior surfaces of the building are heated while the air is removed and replaced with air free of the volatile compounds. The absorbent for passive desorption can be a nanoparticulate metal oxide.

  • Publication number: 20120304857
    Abstract: A contaminant is removed from a gas in a method in which the gas is contacted with a solvent for the contaminant, and the resultant solution is contacted with intercalated graphite onto which the contaminant is adsorbed. The solvent will normally comprise water, and may itself be a contaminated liquid. In a preferred method the solvent is in a reservoir with particulate intercalated graphite; the contaminated gas is delivered to the base of the reservoir; and the gas rises in the solvent mobilizing the intercalated graphite in the reservoir.

  • Publication number: 20120276616
    Abstract: The method and system for methane separation and purification from a biogas includes collecting a raw Biogas gas stream having methane, carbon dioxide, water, sulfur compounds and non-methane organic compound (NMOC) constituents. The Biogas stream is fed into the intake of a liquid sulfur scrubber or a sulfur adsorber unit where the Biogas is separated into a main gas stream routed downstream in the system and a sulfur compounds stream removed from the system. The main gas stream is then processed by an NMOC absorber and further downstream, by an NMOC adsorber. NMOC produced by both NMOC processes is liquefied, removed from the system and stored. Upstream from the NMOC processes, the main gas stream is processed by at least one CO2, N2, O2 gas separation unit that produces a usable product stream of enriched methane gas, and an off-gas stream, which a VPSAU processes for venting and recycling.
