  • Publication number: 20130191552
    Abstract: Methods and systems are provided for determining a flow path for a flow between a source host and a destination host on a computer network wherein the flow has a tuple associated therewith. In one embodiment, a method comprises receiving flow data from exporters on the network, finding one or more exporters that possibly carry the flow, and using the flow data to determine whether any of the one or more exporters that possibly carry the flow include the tuple. For any exporters that include the tuple, the flow data is used to determine a next hop for such exporter. Connection pairs are created between each exporter that includes the tuple and its next hop. The connection pairs are combined to define the flow path.

  • Patent number: 4541852
    Abstract: A system for liquefying and subcooling natural gas wherein compression power is shifted off the closed cycle refrigerant by subcooling the liquid natural gas to a relatively warm exit temperature and subsequently reducing the pressure and flashing the liquefied natural gas to recover a gaseous phase natural gas in excess of plant fuel requirements, the excess being recompressed and recycled to the feed to the process.

  • Patent number: 4411677
    Abstract: A process is disclosed for rejecting nitrogen from a natural gas feed containing nitrogen over a wide range of compositions, e.g. 5-85% nitrogen by volume, under elevated pressure using a single distillation column and a closed loop methane heat pump which reboils and refluxes the column. An intermediate reflux condenser is refrigerated by both the heat pump and overhead nitrogen fraction from the distillation column. The process can handle feeds with increasing nitrogen content and more than 100 ppmv carbon dioxide. The feed can be at pipeline pressure with the natural gas liquid components still present or at lower pressure with natural gas liquids removed. A mixed cryogenic refrigerant can be used in the heat pump as an alternative to methane. The process provides a high methane recovery over the entire feed range, and provides a nitrogen product stream having an elevated pressure suitable for recycling and reinjection to an oil or gas well to improve well head pressure.
