...-shaped riser. At riser top the riser is connected to both 1st and 2nd stage separators, thus reflecting a setup similar to that typically found in a real offshore flowline-riser process plant system. The model fluids used in the current work are air, Exxsol D60 and a viscous water/MEG phase. The system...

.... That is the pressure drop from vessel to separator and not the tubing pressure drop curve. A numerical investigation confirms this for pressure dependent liquid injection. This stability point can be at a higher or lower velocity than the actual loading/flooding point. The results of these experiments are elaborated...

...™, provides information of the operational process and multiphase flow conditions through the wells and templates, subsea compression station, import/export flowlines and topside separation system. The flowline model in the FAS has been tuned against existing field data on pressure drop and liquid...

... ABSTRACT Subsea water removal has emerged as a viable option to prolong the lifetime of brown field installations, increase recovery and generate increased return for operators. This paper presents a thorough literature review of both current subsea liquid-liquid separation installations...

... Abstract Subsea separation is increasingly becoming a critical subject in the context of deepwater field development. Gas-liquid cyclonic separators are the most promising option for subsea separation due to their simplicity, cost effectiveness and ease of intervention. The performance...

... Abstract Erosion experiments were conducted with gas-sand and gas-liquid-sand flow conditions varying air and water velocities in a laboratory scale Gas-Liquid Cylindrical Cyclone Separator (GLCC). The location of highest erosion measured for gas-liquid-sand conditions was slightly above...

... ABSTRACT Large fluctuations in gas and/or liquid production can lead to major disruptions on the topside facilities. Level control of separators becomes difficult with the risk of liquid carry-over into the gas train. Furthermore, the pressure surges accompanying the liquid surges hamper...

... structure, pipeline diameter and riser height and boundary conditions have been inserted into the model to analyze the impact on the severe slugging characteristics, which make the model more generic and reliable. separator equation university riser system l-shaped model multiphase flow...

... ABSTRACT The performance of a particular type of horizontal three phase separator (bucket & weir) was evaluated on the Alba Field, situated offshore of the coast of Equatorial Guinea, by coding a set of equations for the design of the separators. Output parameters such as the oil and water...

... ABSTRACT Vetco has been commissioned by Total to study a subsea gas liquid separation concept, for the development of deepwater fields. The concept's feasibility depends on subsea separation performance, meaning that it depends on a full understanding of dynamic behaviour of the whole subsea...

... INTRODUCTION The flow meter presented in this paper is based on the isokinetic sampling of the gas-liquid mixture, followed by separation and metering of the individual phases. With respect to other MPFMs, the main feature of the meter is the advantage of self-calibration, [1], [2]. Moreover...
