摘要

- device for continuous regulation of the composition of a fluid mixture comprising at least two components of different polarities, which is intended, for example, to be inserted in a separation system which it supplies, in the transport fluid composition stabilized. - it comprises a storage reservoir (3) receiving the mixture from the separation system at least one auxiliary container (6) containing one of the components of the mixture, and means for controlling the transfer of this component from the auxiliary container (6) towards the storage reservoir (3). These control means comprise at least one capacitive probe is tubular (cs) totally immersed in the fluid mixture, a probe (ts) for measuring the temperature of the mixture, a probe (ls) for measuring the level of the mixture in the storage reservoir (3). A regulating assembly (10) connected to the different probes, is adapted to determine the volume of at least one of the components to be transferred into the storage reservoir (3), in order to re-establish a composition of the setpoint for the said mixture. (-, for example, to the control of the simulated moving bed, of distillation columns, etc, 1 / p
