| Abstract |
The Bacman 1 Reinjection system was designed to conduct hot brine in rugged terrain over a 42-meter hump. Automatic pressure control valves maintained pressure upstream of this hump above jluid saturation thus preventing large pressure transients associated with column separation and rejoining. when these valves were removed the system's tolerance for pressure and flow fluctuarions have to be assessed to design appropriate operatirag procedures for the modiJied system. The aim of this project is to create a steady state jlow model of the modiJied Bacman I reinjection system that will allow pressure h'ansient simulator soJtwares to evalwte system's response to jlow and pressure fluctuations. It is also designed to assess how the steady state jlow moakl varied with changes in mass flows, heat transfer andpipe friction losses. These will provide information for selection of an optimum reinjection utilization strategv. The model t h f was conceived had two-phase jlow occurring as much as 10 meters below the hump on its upstream side. Variations in the stable water level of the liquid column upstream of the hump, when the mass jlow, Jiiction loss and heat loss rate changed, were minim1 to injluence the reinjection line utilization stratea. A pressure transient simulation wirh appropriate software is still recommedd to conjirm these results. |
