A New Technique to Eliminate Severe Slugging in Pipeline

Webb1 feb. 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 … how fathers win custody

Slug flow - Wikipedia

WebbOne of the methods for calculating the effect of slug flow loads is the static method. Vertical, horizontal, and resultant forces F can be determined by the formulas: where. θ – bend angle (90 degrees, 45 degrees, etc.) ρ – fluid density. v – slug velocity at the moment then it hits the bend. A – internal pipe cross-section area. WebbHydrodynamic Slugging – refers to gas flowing faster than liquid, causing a wave effect. Examples may be a pipeline traveling down a mountain causing extreme velocities through the piping. Pigging Slugs – refers to the liquid pushed through a pipeline by a piece of equipment referred to as a pig. What is a slug catcher?

WebbSlugs can be generated by different mechanisms in a pipeline: Terrain slugging is caused by the elevations in the pipeline, which follows the ground elevation or the sea bed. Liquid can accumulate at a low point of the pipeline until sufficient pressure builds up behind it. Once the liquid is pushed out of the low point, it can form a slug. Webb30 maj 2013 · Pigging slugs are caused by pigging operations in the pipeline. The pig is designed to push all or most of the liquid of the pipeline to the outlet. This unintentionally creates a liquid slug. Slug Management Slugs have three deleterious impacts on topsides.

Slugging the pipe

Webb2 dec. 2024 · Slug forces are generated when there is 'two-phase' (gaseous and liquid phase) fluid flowing through pipes and slugs of liquid that are formed intermittently travel at relatively high velocity. The liquid slug can cause large reaction forces at changes in direction such as elbows or tee connections. WebbThe occurrence of slug flow in a transportation pipeline can cause many problems in design and operation processes, which include kinetic force on fittings and vessels, pressure cycling, control instability, and inadequate phase separation. Slugging greatly affects the design of receiving facilities.
