  • Publication number: 20240073643
    Abstract: There are many techniques for determining the route of a mobile terminal. Among these techniques, some can be used to estimate this route along roads in a transport network using signalling data. Regarding the cross-referencing of this information with transport network graphs to determine this route, it is known to use hidden Markov models (HMMs). When the position of the mobile terminal is obtained using data collected from the radio communication network to which the mobile terminal is attached, the routes taken by a mobile terminal determined using a HMM on the basis of this information are uncertain. The present method and device helps to overcome this limitation by using a likelihood map of support by a base station to calculate a probability of connection of the mobile terminal to a given base station.

  • Patent number: 9605896
    Abstract: The disclosure includes a process for treating a natural gas containing carbon dioxide wherein the natural gas is separated by a cryogenic process in order to provide, on the one hand, a stream of liquid carbon dioxide, containing hydrocarbons, and, on the other hand, purified natural gas; at least one part of the natural gas is cooled in a first heat exchanger and then in a second heat exchanger before the cryogenic process and/or before a reflux to the cryogenic process; at least one part of the stream of liquid carbon dioxide is recovered in order to provide a stream of recycled carbon dioxide; the stream of recycled carbon dioxide is divided into a first portion and a second portion; the first portion is expanded and then heated in the first heat exchanger, in order to provide a first stream of heated carbon dioxide; the second portion is cooled, then at least one part of the second portion is expanded and then heated in the second heat exchanger, in order to provide a second stream of heated carbon dioxi

  • Publication number: 20140131379
    Abstract: The present document describes a device dispensing portion to be installed on a dispensing fluid tank having an outlet, an inlet and a longitudinal axis which comprises an inlet for receiving a fluid and for being connected to the fluid tank outlet, an outlet for dispensing a fluid, the device dispensing portion defining a longitudinal axis at an angle with the tank longitudinal axis for dispensing fluid substantially free of centripetal swirling action; and a compression single point load cell located at the dispensing portion outlet to dispense fluid at a predetermined amount.

  • Publication number: 20060239879
    Abstract: The method allows pretreatment of an acid gas that can comprise more than 10% H2S, for example a natural gas or a gas associated with the production of a crude petroleum effluent. The gas is dehydrated in unit DH, then cooled by heat exchangers E9 to E12 and by expansion carried out through valve V7. Cooling allows part of the H2S contained in the gas to be condensed. The condensates are separated from the gas in drum B1. The liquid recovered at the bottom of drum B1 is pumped and injected into well P to be sequestered in an underground reservoir or a geologic structure. The gas discharged at the top of drum B1 is depleted in H2S. This gas is sent through line 43 to a treating site in order to be subjected to additional treatments prior to being used.
