Abstract
Transfer by pumping of effluents containing at least one gas phase and at least one liquid phase in a transfer line connecting a source of effluents is optimized by interposing on the line, between the source and the point of designation, a multiphase pump. The rotating speed of the pump is regulated so as to adapt the pump flow rate to at least one of the following parameters: flow rate variation well, variation of the volumetric ratio GLR or pressure drop variations occurring in the line during transfer. The values of the parameters are controlled and adjusted to values comparable with the operation of the pump.
