  • Patent number: 9073808
    Abstract: A process for recovering unreacted olefin in a polyolefin manufacturing process comprising the treatment of a purge bin vent gas. The process involves cooling and condensing the vent gas (purge stream), which contains at least an olefin, a paraffin, and nitrogen, to produce a liquid condensate and an uncondensed (residual) gas stream. Both streams are then passed through membrane separation steps. The membrane separation of the uncondensed gas stream results in a residue stream containing mostly nitrogen and/or paraffin and a permeate stream enriched in either C2+ hydrocarbons or olefin, depending on the type of separation. The permeate from this step is recirculated within the process prior to the condensation step. The membrane separation of the condensate results in a residue stream containing paraffin and a permeate stream enriched in olefin, which may be recycled to the polymerization reactor.

  • Publication number: 20140238234
    Abstract: An aircraft has a ventilation system that employs a plurality of nozzles positioned in a cavity between a sidewall of the aircraft cabin and a section of the aircraft fuselage. The nozzles receive a supply of ventilation air and direct jets of air from the nozzles, through the cavity and into the aircraft cabin. The jets of air produced by the nozzles create low-pressure areas in the cavity. At least one return air opening in the cabin sidewall communicates the low-pressure areas with the cabin interior, whereby the low pressure areas draw air from the cabin interior into the cavity where the drawn air is entrained with the jets of air produced by the nozzles. Devices inside the cavity remove suspended impurities from the air drawn into the cavity. In this manner, the ventilation system filters or sanitizes the air drawn through the system.

  • Patent number: 8709135
    Abstract: An off gas extraction system cleans common sources of off gas, such as storage tanks and polluted soils. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas that can be reintroduced as a treated gas into the off gas source. Alternatively, a regenerative absorber cleans the treated gas by adsorbing residual chemical vapor and concentrates the removed chemical vapors and reprocesses them. If the treated gas is not reintroduced into the off gas source, conventional scrubbers may used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are similarly provided, including novel methods for degassing storage tanks and treating polluted soils to meet current environmental regulations, as well as green technology and sustainability initiatives.

  • Patent number: 8034159
    Abstract: A method for cleaning hydrocarbons from a gas-vapor medium ejected to the atmosphere, formed while storing oil or gasoline or filling a container therewith is provided. The medium is pumped out and compressed in a gas-liquid jet apparatus due to energy of oil or gasoline supplied by a pump. The formed mixture is separated in a separator, where a pressure of 0.7 to 2.5 MPa is maintained, and gas from the separator is compressed in a jet apparatus by oil or gasoline supplied by a pump. The gas medium cleaned from the hydrocarbons is outputted and the saturated absorbent is directed to a desorber where a pressure is generated to be lower than the pressure in the separator. The liquid medium is removed from the separators and to a container or to a storage tank from which oil or gasoline is simultaneously supplied to pump inlets or to the separators.

  • Patent number: 8025860
    Abstract: Acid mist may be removed efficiently from a gas stream using at least one fiber bed mist eliminator operating at elevated pressure of typically at least 2 bar (0.2 MPa), e.g. at about 4 bar (0.4 MPa) to about 50 bar (5 MPa). The invention has particular application in methods for processing carbon dioxide flue gas in which SO2 and/or NOx contaminants are converted at elevated pressure to sulfuric acid condensate and/or nitric acid condensate respectively.

  • Publication number: 20110219949
    Abstract: A gas separation process for treating exhaust gases from the combustion of gaseous fuels, and gaseous fuel combustion processes including such gas separation. The invention involves routing a first portion of the exhaust stream to a carbon dioxide capture step, while simultaneously flowing a second portion of the exhaust gas stream across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, then passing the permeate/sweep gas back to the combustor.

  • Publication number: 20110183276
    Abstract: An apparatus for the degassing of a dust from a synthesis gas produced by a gasification process, is disclosed. The apparatus comprises a main dust separator, a multi-purpose vessel, fluid for degassing and cooling and a storage facility for dust. The synthesis gas produced is conducted via a connecting pipe to a main dust separator, from which a de-dusted raw synthesis gas stream and a dust-like solid which also contains raw synthesis gas in the voids between the dust particles can be removed. The dust-like solid is directed into a multi-purpose vessel equipped with devices for reducing the pressure level so that a tail gas is obtained and a solid containing lower gas quantities in the void fraction remains. There is a device for transporting a solid into a gas exchange apparatus, the latter comprising a gas exchange tank, a dust separator and a feed device for exchange gas. It is possible to reduce the gas exchange tank to atmospheric pressure.

  • Patent number: 7985278
    Abstract: A method is provided for separating CO2 from an exhaust gas flow of a combustion process. The method includes: compressing the gas flow and cooling the compressed gas flow. The method also includes feeding the cooled gas flow to a swirl nozzle and separating the CO2 from the gas flow in the swirl nozzle. The method also includes discharging the CO2 which is separated in the swirl nozzle from the swirl nozzle for separate further treatment. A CO2 separating device is also provided that separates CO2 from an exhaust gas flow of a combustion process that operates with fossil fuels. The device includes a swirl nozzle which is exposed to through-flow of the gas flow, a compressor located upstream or downstream of the swirl nozzle, and a plurality of cooling devices which are provided upstream of the swirl nozzle for cooling of the gas flow which comes from the compressor.

  • Patent number: 7959710
    Abstract: A method of removing siloxanes from a gas that contains siloxanes and water, the method comprising: (a) expanding the gas to cool the gas and freeze at least some of the water in the gas; and (b) removing the siloxanes and frozen water from the expanded and cooled gas. The method may also include compressing the gas prior to expanding it. The step of expanding the gas may include expanding it through a turbine. The method may also include using an energy input mechanism to drive one or both of the compressor or turbine. The ice and siloxanes may be removed from the gas with a cyclonic separator.
