A New Multiphase Header Design – Fluid Distribution in Multi-Pump Operation

Parallel operating multi-phase pumps interact due to hydraulic coupling. Asymmetrical distribution of the multi-phase mixture can then lead to an uneven working load in parallel operating multi-phase pumps. Thus the operating range of the complete pump system is limited by the marginal operation of individual pumps.
Homogenization of the flow conditions can make the operating range of a pumping system with parallel operating multi-phase pumps fully usable. For this purpose a specific header design was examined, the fundamentals of which are discussed and initial operational experiences are described.
