A highly transient flow regime called riser slugging can develop in pipelines from wellheads to separation tanks which introduces severe oscillations of pressure and flow rates in off-shore processes. Mitigation of the intensity of riser slugging may be achieved via anticipative control actions on valves positioned at the entrance and at gas/oil exits of the separators. In Phase 1, this work is...

The main problem discussed in this study is the effort to improve quality of shrimp pond water, especially low dissolved oxygen levels by modifying angle aerator wheel. results showed that (DO) were very important culture and paddle wheel was a useful tool intensive aquaculture systems because it could produce DO as needed. used model designed using Solidworks software tested at scale 1:10 with...

It is also common for flowmeters to be installed downstream of a two or three phase separator. If the well conditions change or the separator has been incorrectly sized, then it is possible that the oil liquid outlet may have some gas carry under. The effects of gas entrainment on the output of ultrasonic and Coriolis meters has been reported previously [1] [2]. It is already known that gas ent...

The Physics Teacher ◆ Vol. 52, March 2014 DOI: 10.1119/1.4865514 wheel. We then measured the actual acceleration of the wheel in the CRT by video analysis of its motion and determined the moment of inertia of the wheel along with its mass and dimensions. We could then compare the force, which really acts on the wheel to produce the observed motion to the maximum impulsive force that is supplied...

supersonic separators have found extensive applications in dehumidification of natural gases since 2003. unlike previous studies, which have investigated the inlet conditions and nozzle geometry of supersonic separators for pure fluids, the present study employed a combination of momentum, heat, and mass transfer equations along with virial equation of state (eos) to inspect the effect of inlet...

The main problem that is often found in the failure of microalgae production poor water quality during maintenance period. One causes deteriorating lack oxygen which endangers can inhibit cell growth so it reduce its productivity. On this basis, efforts are needed to refresh or aeration help increase dissolved (DO) level container using a paddle wheel. development an aerator blade design has op...

This study evaluated the separation efficiency and developed a pressure drop model for a multicyclone separator used for natural gas purification. The collection and grade efficiencies of a multicyclone separator with 15 single cyclone separators were evaluated at inlet velocities of 6–24 m/s and particle concentrations of 30–2000 mg/m at atmospheric pressure and room temperature. The experimen...
