Process for optimizing a device for regulating and damping a multiphase flow and device obtained with the process

摘要

The characteristics of a device for regulating and damping the composition fluctuations of a multiphase flow comprising a tank or surge drum and a sample tube located between a source of effluents and a multiphase pump are optimized by selecting the volume of the tank and the distribution of the apertures of the sample tube so as to define an average level around which the level of the liquid-gas interface is stabilized and so that the volume of the liquid phase corresponding to this average level is at least equal to the volume of liquid necessary to discharge any foreseeable volume of gaseous phase coming from the source of effluents. In case of a large volume of gaseous phase, an unpierced tube is introduced inside the sample tube.
