Slug catchers can be used continuously or on-demand. A slug catcher permanently connected to the pipeline will buffer all production, including the slugs, before it is sent to the gas and liquid handling facilities. This is used for difficult to predict slugging behaviour found in terrain slugging, hydrodynamic slugging or riser-based slugging.
In fluid mechanics, slug flow in liquid–gas two-phase flow is a type of flow pattern. Lighter, faster moving continuous fluid which contains gas bubbles - pushes along a disperse gas bubble. [ 1 ] [ 2 ] Pressure oscillations within piping can be caused by slug flow. [ 3 ]
Slug flow is where large frothy waves of liquid form a slug that can fill the pipe completely. These slugs may also be in the form of a surge wave that exists upon a thick film of liquid on the bottom of the pipe. Elongated bubble flow consists of a mostly liquid flow with elongated bubbles present closer to the top of the pipe.
Slugging, [1] also known as casual carpooling and flexible carpooling, [2] is the practice of forming ad hoc, informal carpools for purposes of commuting, essentially a variation of hitchhiking. A driver picks up these non-paying passengers (known as "slugs" or "sluggers") at key locations, as having these additional passengers means that the ...
A slug catcher is a type of vapor–liquid separator that is able to receive a large inflow of liquid at random times. It is usually found at the end of gas pipelines where condensate may be present as slugs of liquid.
It's flu season right now, and the U.S. is in the midst of a wave that's straining hospitals.But not all influenza is the same. There are some notable differences between flu A and flu B strains.
Column separation is a phenomenon that can occur during a water-hammer event. If the pressure in a pipeline drops below the vapor pressure of the liquid, cavitation will occur (some of the liquid vaporizes, forming a bubble in the pipeline, keeping the pressure close to the vapor pressure). This is most likely to occur at specific locations ...
A "pig" is a tool that is sent down a pipeline and propelled by the pressure of the product flow in the pipeline itself. There are four main uses for pigs: Physical separation between different fluids flowing through the pipeline; Internal cleaning of pipelines; Inspection of the condition of pipeline walls (also known as an inline inspection ...
