1. An apparatus for use in controlling a differential pressure between a fluid column upstream and downstream of the apparatus, said apparatus comprising at least two impellers, each having a rotatable shaft provided with a plurality of vanes or blades, the impellers being disposed in a housing which constitutes a portion of a pipeline, said shafts communicating with a load, said apparatus is arranged for receiving the fluid column between the shafts of the impellers, whereby the velocity of the fluid column through the apparatus substantially corresponds to the velocity of the fluid column immediately adjacent to the impellers of the apparatus, and the impellers of the apparatus are arranged for providing a rotatable barrier for the fluid column in that at least one of the vanes or blades of each of the impellers is in substantially sealing contact with a first portion of the internal jacket surface of the housing, said barrier being influenced by said load to provide any predetermined differential pressure between the fluid column upstream and downstream of the apparatus, wherein at least one of the blades of each of the impellers is constantly in substantially sealing contact with an elongated dividing element which is disposed in a portion of the apparatus, said dividing element providing a partition between the impellers and extending past a straight line through said shafts. 2. The apparatus in accordance with claim 1, further comprising a longitudinal axis of the dividing element is substantially parallel to an axis extending between an inlet portion and an outlet portion of the apparatus. 3. The apparatus in accordance with claim 1, further comprising at least a portion of the dividing element is provided with a biconcave shape. 4. The apparatus in accordance with claim 1, the dividing element comprising at least one fluid column control element pivotally disposed at a portion of the dividing element to control of the distribution of the fluid column between the two impellers. 5. The apparatus in accordance with claim 1, said load comprising a generator for producing electrical energy. 6. A method for controlling a differential pressure in a fluid column located within a pipeline, said method comprising: integrating in the pipeline an apparatus which includes at least two impellers, either one comprising a rotatable shaft provided with a plurality of vanes or blades,disposing the impellers in a housing which constitutes a portion of the pipeline, said shafts communicating with a load, whereby the velocity of the fluid column through the apparatus substantially corresponds to the velocity of the fluid column immediately adjacent to the impellers of the apparatus, and the impellers of the apparatus are arranged for providing a rotatable barrier for the fluid column in that at least one of the vanes or blades of each of the impellers is in substantially sealing contact with a first portion of the internal jacket surface of the housing, said barrier being influenced by said load to provide any predetermined differential pressure between the fluid column upstream and downstream of the apparatus; andcontrolling the rotation of said impellers by the load communicating with the shafts of the impellers to provide any predetermined differential pressure between the pressures of the fluid column upstream and downstream of the apparatus. 7. The method in accordance with claim 6, further comprising producing electrical energy from the load. 8. The method in accordance with claim 6, further comprising including in the apparatus a dividing element for providing a partition between the impellers. 9. The method in accordance with claim 6, further comprising distributing the fluid between the impellers with the dividing element and a fluid column control element. 10. The method in accordance with claim 6, further comprising the steps of: integrating the apparatus in a pipeline which extends between a petroleum underground formation and a petroleum installation;conducting a petroleum fluid through the pipeline from the underground formation to the installation; andcontrolling the rotation of the impellers for reducing the pressure in the pipeline between the underground formation and the installation.
