  • Patent number: 9028592
    Abstract: A system and method of reducing the net carbon dioxide footprint of an industrial process that generates power from the combustion of hydrocarbon fuels in which ambient air is admixed with up to 50% by volume of an effluent gas from the power generator of the industrial process, in order to substantially increase the CO2 concentration in the air prior to treatment. The treatment comprises adsorbing CO2 from the admixed ambient air utilizing a cooled, porous substrate-supported amine adsorbent, wherein the porous substrate initially contacts the mixed ambient air containing condensed water in its pores, which act as an intrinsic coolant with respect to the exothermic heat generated by the adsorption process.

  • Patent number: 8926734
    Abstract: An exemplary embodiment of the present invention provides an induced-draft injection system comprising an injection line in fluid communication with a duct under negative pressure, a particulate storage containing particulate, and a feeder receiving the particulate from the particulate storage and feeding the particulate to the injection line. The negative pressure in the duct supports the transportation of at least a portion of the particulate through the injection line and into the duct. Inside the duct, a binding portion of the particulate is bound to a portion of mercury in a flue gas passing through the duct, thus enabling a portion of the mercury to be filtered out of the flue gas.

  • Patent number: 8500855
    Abstract: A method and a system to remove relatively pure carbon dioxide directly from ambient air. The method comprises generating process heat, to co-generate substantially saturated steam; alternately and repeatedly exposing a sorbent to a flow of ambient air, at substantially ambient conditions, to sorb, and therefore remove, carbon dioxide from said ambient air, and exposing the CO2-laden sorbent to a flow of the co-generated steam, at a temperature in the range of not greater than about 130° C, to release the carbon dioxide, thereby regenerating the sorbent, and capturing relatively pure carbon dioxide. To render this process more efficient, admix with the air a minor amount of a pre-treated effluent gas containing a higher concentration of carbon dioxide than in the atmosphere. The captured carbon dioxide can be stored for further use, or sequestered permanently. The purified carbon dioxide is useful for agriculture or chemical processes.

Perforations are disposed along the wall of a tank in a path generally parallel to the tank's axis. Stoppers are provided for stoppering the perforations. With the perforations so stoppered, a gas is introduced at high pressure into the tank. Thereafter, quickly unstoppering the perforations releases the gas from the tank in form of a longitudinally disposed, sharp puff of gas moving in a direction perpendicular to the tank's axis. If the tank is placed vertically alongside or within a space receiving gas from a panel bed, the sharp puff can effectively puffback the panel bed.

  • Patent number: 8372180
    Abstract: The invention provides a process for controlling the moisture content of a supply gas for use in drying a product, which process comprises the steps of: (a) providing the supply gas; (b) optionally heating the supply gas; (c) determining the temperature and the moisture content of the supply gas; (d) contacting the supply gas with a rotating desiccant wheel, whereby the rotating speed of the desiccant wheel is controlled by means of the data on the temperature and the moisture content as obtained in step (c) in combination with the corresponding sorption isotherm of the desiccant; and (e) recovering the dehumidified supply gas as obtained in step (d). The invention further provides a dehumidified gas obtainable by said process, a dehumidifier system, a process for drying a product comprising bringing the product into contact with a dehumidified gas as obtained in accordance with the invention, and a product obtainable by said drying process.

  • Patent number: 8353978
    Abstract: A multi-step process for removing CO2 from a process gas stream having CO2 and other gaseous components commences by adjusting the temperature of a CO2 laden process gas stream to be between about 80° and about 500° C. A first part of the temperature adjusted process gas stream is taken and contacted with a adsorbent in thermal contact with a heat-exchange surface. The remainder of said temperature adjusted process gas stream is taken and contacted with said heat-exchange surface to transfer heat to said adsorbent, thus causing any adsorbed CO2 to be desorbed for collection, and to cool said process gas stream remainder and removing any condensate from said cooled process gas stream remainder. The cooled process gas stream remainder is passed in contact with a cooled section of said adsorbent to adsorb CO2 therefrom, producing a CO2 depleted process gas stream. The desorbed CO2 is withdrawn for collection.

  • Publication number: 20120325088
    Abstract: A method and reactor for removing a component from a gas stream is provided. In one embodiment, the method includes providing the gas stream containing the component that is to be removed and adsorbing the component out of the gas stream as the gas stream rises via microbeads of a sorbent falling down an adsorber section of a reactor.

  • Patent number: 8277542
    Abstract: The present invention relates to use of carbon-based sorbents such as activated carbon for controlling vapor phase mercury emissions in coal-fired power plant flue gases or waste incineration flue gases. The invention features new methods that improve the performance of carbonaceous sorbents for mercury control compared to the previous methods. One method consists of injecting the sorbent (consisting of at least some carbonaceous material) into the flue gas where the flue gas temperature is at a value above about 1100° F. and below about 2000° F. The invention also consists of injecting the sorbent within or upstream of an economizer section in a coal-fired power boiler. Injecting the sorbent at the locations indicated above, rather than further downstream, provides increased residence time for contact between the flue gas and the sorbent resulting in increased mercury capture, improved sorbent utilization, and improved fly ash properties.

  • Patent number: 8187364
    Abstract: A method and apparatus for simultaneously removing alkali chlorides from an industrial process and purifying vaporizable contaminants such as mercury from a particulate material. Gases containing alkali chlorides are cooled to a temperature above the boiling point of the contaminants and below the boiling point of the alkali chlorides. Particulates rich in alkali chlorides are removed from the gas stream with a first dust collector. The gas stream cleaned of alkali chlorides is directed to a reaction area where particulate material containing mercury contaminants is inserted into the gas stream to vaporize the contaminants from the material and entrain the cleaned material in the gases. The gases are directed to a second dust collector to remove the entrained particulate material, after which a sorbent or chemical reagent is injected in the gases to interact with the contaminants and form a contaminant containing product that is entrained in the gases and thereafter separated from the gases.
