  • Patent number: 10702825
    Abstract: Outside air is cooled and dehumidified by a pre-cooler to pass through an adsorption zone of a carbon dioxide adsorbing rotor, producing air having a low carbon dioxide concentration which is cooled by an intercooler. The air that has passed through the intercooler is passed through an adsorption zone of a moisture adsorption rotor and then supplied to a low humidity working chamber. Return air from the low humidity working chamber may be mixed with the air leaving the pre-cooler. A part of the air which passed through the intercooler is branched to pass through a purge zone of the moisture adsorption rotor before being sent to a regeneration zone of the humidity adsorption rotor. Air that passed through the regeneration zone of the humidity adsorption rotor is mixed with outside air and then passed through a regeneration zone of the carbon dioxide adsorption rotor before being exhausted.

  • Patent number: 10689254
    Abstract: A method and system for abating the emissions of at least sulfur dioxide present in a tail gas emitted from sulfur recovery units are provided. The invention is characterized by the provision of at least two adsorber units in a parallel arrangement. While one adsorber is in an adsorption mode, it receives a gas contaminated w/ sulfur dioxide and adsorbs and removes the sulfur dioxide out of the gas. The other adsorber is in regeneration mode, and receives an acid gas stream comprising hydrogen sulfide as well as an oxygen-containing gas to regenerate the spent adsorbent material and produce an off-gas comprising hydrogen sulfide and sulfur dioxide. This off-gas is then recycled back to the sulfur recovery unit.

  • Patent number: 10486132
    Abstract: Copper adsorbents which are resistant to the reduction by the components of the synthesis gas at normal operation conditions. The adsorbents are produced by admixing small amounts of an inorganic halide, such as NaCl, to the basic copper carbonate precursor followed by calcination at a temperature sufficient to decompose the carbonate. The introduction of the halide can be also achieved during the forming stage of adsorbent preparation. These reduction resistant copper oxides can be in the form of composites with alumina and are especially useful for purification of synthesis gas and the removal of mercury, arsine, phosphine, as well as hydrogen sulfide.

  • Patent number: 10239017
    Abstract: A method for removing carbon dioxide directly from ambient air, using a sorbent under ambient conditions, to obtain relatively pure CO2. The CO2 is removed from the sorbent using process heat, preferably in the form of steam, at a temperature in the range of not greater than about 130° C., to capture the relatively pure CO2 and to regenerate the sorbent for repeated use. Increased efficiency can be achieved by admixing with the ambient air, prior to contacting the sorbent, a minor amount of a preferably pretreated effluent gas containing a higher concentration of carbon dioxide. The captured carbon dioxide can be stored for further use, or sequestered permanently. The above method provides purified carbon dioxide for further use in agriculture and chemical processes, or for permanent sequestration.

  • Patent number: 9181504
    Abstract: Method and system for gasifying biomass. Tar loaded gas from the reactor for gasifying the biomass is subjected to a saturation and absorption treatment with a first and second fluid respectively. The first fluid comprises aromatic hydrocarbons whilst the second fluid comprises linear hydrocarbons. Tars received in the aromatic fluid is entered together with such fluid in a separation column. Separation is effected based on evaporation temperature and the lighter fraction is returned to the inflow of the saturation separator. The heavier fractions are either discharged or sent back to the biomass reactor. An intermediate buffer vessel can be provided between the discharge of the saturation cleaner and the separator.

  • Patent number: 9138677
    Abstract: A carbon capture system, such as a chilled ammonia process, is provided that includes with a cooling system, a carbon dioxide absorption system and an ammonia absorption system. The ammonia absorption system includes an absorber column to receive carbon dioxide lean gas stream having ammonia and to receive an absorbent, wherein the absorbent absorbs ammonia from the carbon dioxide lean gas stream to provide an ammonia reduced gas stream and an ammonia rich absorbent. Further, an ammonia stripper is provided to receive the ammonia rich absorbent and to receive a portion of the gas stream, wherein the gas stream flows through the ammonia stripper to heat the ammonia rich absorbent to release the ammonia therefrom and provide an ammonia rich gas stream and an ammonia reduced absorbent.

  • Publication number: 20150125368
    Abstract: The present invention describes the process of preparing ceramics for the absorption of ACIDIC gases, which worsen the greenhouse effect, that are released in combustion systems, or that are present in closed environments. In relation to carbon dioxide, principal target of the present invention, the process of absorption, transport, processing and transformation of the gas into other products is described. The process uses ceramic materials prepared through the solid mixture of one or more metallic oxides, with one or more binding agents and an expanding agent. The product generated can be processed and the absorbent system regenerated. The carbon dioxide obtained in the processing can be used as analytic or commercial carbonic gas, various carbamates and ammonium carbonate.

    Abstract: In some embodiments, the present disclosure pertains to methods of capturing a gas from an environment by associating the environment (e.g., a pressurized environment) with a porous carbon material that comprises a plurality of pores and a plurality of nucleophilic moieties. In some embodiments, the associating results in sorption of gas components (e.g., CO2 or H2S) to the porous carbon materials. In some embodiments, the methods of the present disclosure also include a step of releasing captured gas components from porous carbon materials. In some embodiments, the releasing occurs without any heating steps by decreasing environmental pressure. In some embodiments, the methods of the present disclosure also include a step of disposing released gas components and reusing porous carbon materials. Additional embodiments of the present disclosure pertain to porous carbon materials that are used for gas capture.
