Fremgangsmåte og anordning for å separere og måle volumet av de forskjellige faser av en blanding av fluider

摘要

Is measured after decantation, the volumes of the different phases of a multi-phase mixture contained in a container, essentially by comparing by means of two pressure sensors relative or differential (14, 15), the pressures generated by three columns fluids of the same height filled, one completely with at least one of the fluids (a liquid phase, for example, surmounted by a gaseous phase); a second with at least two of the fluids (two liquid phases, for example, on top of the same gas phase). The container may be, for example, a cell which is elongated (11) of calibrated section, disposed vertically and provided with pressure taps in three distinct points of its height, communicating with the sensors by pipes fine. A treatment assembly (18, 19) combines the pressure measurements in order to obtain, in particular, the respective volumes of the phases. & br / applications of the measurements of volume in the various containers, in particular, installations of chemical engineering, tests of the geological samples porous saturated with a multi-phase mixture, etc, 1 / p
