  • Patent number: 8282899
    Abstract: Solvent absorption processes for separating components of an impure feed gas are disclosed. The processes involve two stages of gas-liquid contacting, namely a first, absorption stage and a second, stripping stage. In the case of a carbon dioxide (CO2)-containing methane gas as an impure feed gas, contacting, in the stripping stage, the solvent effluent from the absorption stage with a recycled vapor fraction of the solvent effluent from the stripping stage can improve the recovery and purity of not only the methane (and/or other light hydrocarbons in the impure feed gas), but also that of the CO2 contaminant gas.

  • Publication number: 20120240650
    Abstract: A method for the recovery of hydrogen sulphide and other acid gas fractions from sour wellsite gas in hydrocarbon production is provided. The selected acid gas fractions are absorbed into a noncorrosive and transportable solvent solution at the wellsite, the rich solvent solution being transported to a central plant location where it is desorbed from the solvent solution for further handling or processing. The lean solvent solution can then be recycled. Multiple acid gas fractions could be recovered from the sour gas in question using a single appropriate solvent solution. Carbon dioxide could be absorbed and desorbed at the wellsite rather than at the central plant location. Clean gas is yielded at the natural gas into solvent wellsite for downstream processing or sale.

  • Patent number: 8197857
    Abstract: A method for the elimination of carbon dioxide from waste gases includes the following steps. First, waste gases, which include carbon dioxide, are provided from a source for waste gases. Next, the waste gases are contacted with an absorbent composition that includes perfluorodecalin solution. The waste gases, especially the carbon dioxide, are then absorbed by the absorbent composition. The absorbent composition thereby absorbs the waste gases to eliminate the carbon dioxide.

    Abstract: A system and method of cleaning and scrubbing contaminants, including sulfides, from an unclean or raw gas includes one or more containers, each of which include a gas permeable receptacle or bag containing an appropriate gas scrubbing medium for removing the contaminants from the gas stream. A gas extraction device is adapted via inserted into the gas scrubbing medium with the gas permeable receptacle wherein the gas extraction device is connected to at least one gas outlet port in the container. A series of containers can be used wherein the containers are connected sequentially to remove the gas. A system for bypassing one of the plurality of containers in order to clean out the container while the gas cleaning mechanism is still in operation is also described.

  • Publication number: 20120111189
    Abstract: Method and system to capture target gases from all kind of point-sources, as well as from ambient air and surface waters, sediments or soils by advantage of large differences in Henrys law constants. For gas dissolution in water the constants favor dissolution of e.g. CO2 compared to the main constituents of flue gases like N2 and O2. The main principle is to dissolve the gases—release of the non-dissolved part stripping the liquid for the dissolved gases, which are enriched in target gas. Further steps can be used to reach a predetermined level of target gas concentration.

  • Publication number: 20120031269
    Abstract: A method and a device for purifying a carbon-dioxide-containing gas stream are described, in which the gas stream is first subjected in a lower section (3) of an absorption column (1) to a prescrubbing for conditioning the gas stream and subsequently in an upper section (8) of the absorption column (1) the carbon dioxide is scrubbed out from the gas stream at least in part with a scrubbing liquid. For improving the construction of the absorption column it is proposed that the entire scrubbing liquid loaded with the carbon dioxide which is scrubbed out is taken off from the absorption column (1) and fed to a receiver tank (11) arranged outside the absorption column (1) and subsequently applied to a scrubbing liquid pump (12) which pumps the scrubbing liquid to a scrubbing medium regeneration stage.

  • Publication number: 20110315014
    Abstract: A method for removing SOx (x=2 and/or 3) from gas using a solution having polyethylene glycol as the main ingredient. First, SOx in the gas is absorbed by the solution of polyethylene glycol. Second, the solution of polyethylene glycol which has absorbed SOx is regenerated by one or more of the heating, vacuum, ultrasonic, microwave or radiation methods, thereby releasing the by-products of sulfur dioxide and sulfur trioxide. The regenerated solution of polyethylene glycol is recycled. When the water content of the regenerated solution of polyethylene glycol is high enough to affect the desulfurization, it needs to be removed. Removal methods include heating and rectification, absorption using a water absorbent, or a combination of these methods. The polyethylene glycol solution is recycled after dehydration.
