What is the main purpose of a slug catcher?
A Slug Catcher is used to collect liquids that have settled in flow lines which can overload the gas/liquid handling capacity of the plant especially during pigging operations. The Slug Catcher helps protect your valuable production equipment from abrupt large bursts of liquids entering your gas stream.
Can a slug catcher separate gas from liquids?
A Parking Loop slug catcher combines features of the vessel and finger types. The Gas/Liquid Separation occurs in the Vessel, while the Liquid is stored in the parking loop shaped fingers.
What is a pipeline slug catcher?
Slug catcher is a static equipment used in the upstream oil production facilities to minimize the slug from oil and gas pipeline. Fluids extracted from oil and gas reservoirs contain crude oil, natural gas, water, salts etc. A slug is a large quantity of gas or liquid that exits in the pipeline.
What is slugging oil and gas?
1. n. [Production Testing] Accumulation of a water, oil or condensate in a gas pipeline. These fluids need to be removed using a pig. See: pigging.
What is the difference between pig launcher and pig receiver?
A Launcher is located at the upstream end of the pipeline to launch the Pig into the pipeline. A Receiver is located at the downstream end of the pipeline to remove the Pig from the pipeline.
How are pipelines cleaned?
Pipeline cleaning by means of a spherical or cylindrical pipe pig is a convenient and effective way of cleaning the pipe without interrupting the flow. The pipe is introduced into the pipeline via a trap, which is equipped with a launcher and receiver.
What is slugging in oil and gas industry?
slugging, liquid accumulates at the bottom of the riser and the. pipeline, blocking the passage of gas flow. This results in a. pressure buildup in the gas phase that will push the liquid slug up. the riser.
How do you clean a slugging?
Short-Cut Slugging Method
- Remove Makeup. In the evening, remove your makeup with micellar water or a cleansing lotion.
- Wash Your Face. Wash your face with cool water and a mild cleanser.
- Apply Petroleum Jelly.
- Wash Your Face.
- Moisturize.
What is kicker line in pigging?
Kicker line is used to pressurize the upstream side of pig so it can be launched. In case of receiver, kicker line provides an outlet for fluids arriving in the pig trap. Normally when pigging is not being performed, kicker line is closed using normally closed valve.
Where do slugs go at night?
They stay under logs and stones or under ground cover. They also hide under planters and low decks. At night they come out to eat. They make a slimy trail as they move around.
What is slug in drilling?
1. n. [Drilling Fluids] A volume of mud that is more dense than the mud in the drillpipe and wellbore annulus.
How does a finger type slug catcher work?
A finger-type slug catcher uses pieces of large-diameter pipe instead of a conventional vessel to provide a buffer volume (Fig. 2). Since pipe can be more easily designed to withstand high pressures compared to a vessel, this design is better suited for large-diameter pipes.
How do I choose the best slug catcher?
Finger style slug catchers work best when receiving and storing large volumes of hydrocarbon slugs, typically from pigging, with high gas flow rates. When optimizing for the most cost effective design for your site, the points below should help define your approach. 1. Design Codes
How do you separate gas and liquid in a slug catcher?
The gas/liquid separation occurs in the vessel, while the liquid is stored in the stored-loop-shaped fingers. A possible hybrid design can be used, with a vessel designed for the vapor/liquid separation and finger pipe work as the storage medium, as illustrated in Fig. 1. Fig. 1. Stored-loop-type slug catcher.
What is the CSA code for a slug catcher?
Finger type slug catchers are typically designed to a gas transmission code like ASME B31.8 or CSA Z662 in Canada. In rare cases, the slug catcher is located “inside the fence” of a gas processing plant which then requires the use of B31.3 design code.
