Abstract: This disclosure relates in general to systems and methods for spot checking flow properties of a multiphase mixture containing one or more hydrocarbons flowing through a pipeline or the like. More specifically, but not by way of limitation, embodiments of the present invention provide systems and methods for creating slug-type flows of isokinetically obtained samples of the multiphase mixture flow. By spot checking the slug-type flow of an isokinetically obtained sample of the multiphase flow, embodiments of the present invention may provide for determining flow properties of gas, oil/condensate and/or water components of the multiphase flow. In certain aspects of the present invention, an active sampling device may be used to enrich one of the phases of the slug-type flow of the sampled multiphase mixture and/or take a representative sample of one of the phases of the slug-type flow of the sampled multiphase mixture.

Abstract: A method of detecting an additional element from a plurality of other elements forming a multiphase flow. The method comprising: measuring an energy spectrum response based on electromagnetic irradiation of the multiphase flow. Determining a fraction concentration of the other elements forming the multiphase flow based on a lower energy peak in the spectrum response and detecting an additional element in the multiphase flow based on measuring a variation of a higher energy peak in the spectrum response. It is also possible to measure the quantity of the additional element and to compensate the fractional concentrations of the respective n-phase measurements.

Abstract: An apparatus and method for measuring a mass flow rate of a multi-phase fluid flowing through a conduit. The apparatus includes a differential pressure element located in the conduit, wherein a first differential pressure measurement device is in communication with the multi-phase fluid between a first and second position across the differential pressure element and is able to measure a first fluid differential pressure. A second differential pressure measurement device is in communication with the multi-phase fluid between a third and fourth position across the differential pressure element and is able to measure a second fluid differential pressure. A processor is in communication with the first and second differential pressure measurement devices, and is able to calculate the Reynolds number and discharge coefficient using the first and second fluid differential pressures. The processor is also capable of calculating the mass flow rate by using the Reynolds number and discharge coefficient.

Abstract: A detector (1) is used distinguishing a phase from a multiphase fluid mixture. The detector comprises: an optical probe (2) for optically distinguishing one of the phases from the multiphase fluid mixture, the optical probe having a tip (20) in contact with the multiphase fluid mixture, and a detector cell (3) arranged to be coupled to a multiphase fluid mixture flowing line (L) and to the optical probe (2). The detector cell (1) further comprises: an internal flowing line (4) arranged so that the phases of the multiphase fluid mixture flowing in the internal flowing line are driven-on by capillarity effect, and a bore (5) coupled to the internal flowing line for positioning the optical probe in the detector cell so that the multiphase fluid mixture flows substantially around the tip (20) of the optical probe.
