http://www.oilfieldwiki.com/wiki/Slugging_and_Liquid_Handling WebTerrain Slugging When a flow line system passes through uneven terrain with severe dips and sudden rises, liquid phases are likely to accumulate in the lower levels. With time, the volumes at these lower elevations reach saturation and create a lot of pressure that pushes the liquid out, all at once, causing a slug. Hydrodynamic Slugging

At low flow rate, the liquid accumulates at the riser base, blocking the gas flow while the riser column gets filled with liquid (slug formation stage); the gas is compressed in the upstream pipeline, causing a pressure … symptomatische aaaWebFeb 1, 1985 · Abstract. Severe slug flow (i.e., terrain-dominated slug flow) was studied in a simulated offshore pipeline riser-pipe system. Severe slug flow is characterized by extremely long liquid slugs generated at the base of the vertical riser. This phenomenon occurs at low gas and liquid flow rates and for negative pipeline inclinations. Slugging in some … thai carrboro
