Abstract (en)
[origin: EP0549440A1] The characteristics of a device for regulating and damping the fluctuations in composition of a polyphase flow, comprising a buffer storage vessel or sphere (2) and a sampling tube (3) placed between a source of effluents (5) and a polyphase pump (P) are optimised by selecting the volume of the storage vessel and the distribution of the orifices (4) in the sampling tube so as to define a mean level about which the level of the liquid-gas interface (6) is stabilised and so that the volume of the liquid phase corresponding to this mean level is at least equal to the volume of liquid needed to remove all the foreseeable volume of gas phase originating from the source of effluents. In the case of a large volume of gas phase, an unpierced tube is introduced inside the sampling tube. <IMAGE>
