  • Patent number: 10473563
    Abstract: The present invention refers to a method for the isokinetic sampling of liquids and gases present in streams having many fluid phases, and to an apparatus suitable for achieving it. The method and apparatus have application in particular in the field of oil extraction, wherein, after the extraction of liquid and gaseous hydrocarbons possibly accompanied by water and suspended solids, it is necessary to know the composition of the mixture extracted and also the flow rate of the single phases.

  • Publication number: 20150300147
    Abstract: Apparatus and process for recovering hydrocarbons from an underwater well or pipeline in uncontrolled release conditions, wherein the apparatus comprises a separation chamber (11) having an inlet (11a) for a multi-phase stream comprising the flow of hydrocarbons (23) in outlet from the underwater well or from the underwater pipeline, and a plurality of outlets (13, 14, 18) for respectively conveying a mainly gas phase (21), a mainly light liquid phase (22b) and a mainly heavy liquid phase (22a) coming from the separation of the multi-phase stream in inlet, the inlet (11a) consisting of a directioning body (31) of the multi-phase stream towards the inside with respect to the separation chamber (11), the directioning body (31) comprising a first inlet end (31c) of the multi-phase stream and a second end (31b), opposite to the first end (31c), the second end (31b) being in fluid communication with the separation chamber (11) and it is characterised in that an outlet (18) for the mainly heavy liquid phase (22a) o

  • Patent number: 8770040
    Abstract: An apparatus for measuring a multiphase fluid stream which flows in a pipe (2) comprising: a measuring unit (11), coaxial to the pipe, consisting of an isokinetic sampling device (1) suitably configured for allowing the equidistribution of the flow at the inlet in n channels (6) having an area A, of which m are sampling channels and a flow restriction (13) both equipped with differential pressure measuring means (12, 14), a phase separator (15), connected to the sampling device, measurers and regulation means downstream of said separator. A method in accordance with said apparatus which comprises: the isokinetic sampling of a portion q of the multiphase flow Q at the inlet, measuring the flow-rates of the liquid qL and gas qG of the portion sampled and calculating the liquid and gas flow-rates (QL and Q0) from the sampling sections according to the equations QG=n/tn qG and QL=n/m qL. The method provides isokinetic sampling for portions of flow removed ranging from 5% to 20%.

  • Patent number: 8730461
    Abstract: Method for the quantification of the fugitive gas flow from a dispersed source (A) by monitoring with a remote detection optical instrument mounted on an aircraft (UAV) which moves at a determined height along a plane (S) perpendicular to the direction of the wind field (u), such wind field being known through suitable positioning of meteorological stations within and in areas neighboring the site to be monitored according to known techniques and use of commercially available diagnostic meteorological models.
