Multiphase pumping system with feedback loop |
摘要 |
The invention relates to a pumping system for applying a sufficient pressure increase to multiphase effluents for them to be conveyed from a source such as an petroleum producing well to a remote destination point. To improve pump function and render management of effluent transfers more flexible, the system has a loop (7) for recycling a fraction of the multiphase effluents leaving pump (1) to the inlet thereof, comprising preferably a tap (5) such as a T formed to decrease the volumetric ratio GLR of the recycled effluents. A regulator such as a control valve (8) and a buffer tank and an element (9) such as an ejector-mixer are interposed in the loop to use part of the energy of the effluents tapped off. The invention has application for offshore pumping facilities.
