What is Sligcatcher?
Slugcatcher is part of a pipe system that distracts the energy of liquid slugs that occasionally occur, and temporarily stores any excess material for later processing. Slugs are large volumes of liquid or gas, east of the pipes as units. Slugcatcher is located at the end of the pipeline and acts as a buffer for protection of processing equipment. It can be permanent accessories designed to compensate for all entry or brought online only if the slug is expected.
pipes that allow the flow of two -phase or simultaneous transport of liquid and gas are subject to slug formation. Oil from the drill site carries pockets of natural gas and water. Gas pipes often experience hydrocarbon condensation and water accumulation or chemical processing. If the flow of liquid and gas in the pipeline is not constant, plugs consisting almost exclusively from gas or liquid. This accumulation is called slugs.
Variations in the height of the pipe due to Terrain MIt can cause the liquid to accumulate at low points and block the gas flow. The gas is compressed for blockage until the pressure overcomes the weight of the accumulation and processes it. A liquid slug is formed, which is pushed before the expanding gas. This process is responsible for both off -road and based on a coastal drilling device.
Under certain conditions, the gas causes slower moving liquid. If the height of the wool reaches the upper part of the pipe, the snail begins. Slig, pushed along the gas flow, accumulates the volume in the direction of the flow and loses the volume in the opposite direction. The relative degree of accumulation and loss determines whether the results of a permanent slug. This forming process is called hydrodynamic repayment.
Pigging includes inserting equipment into pipes for inspiration, maintenance or cleaning. During this process, the pipe flow usually does not stop. As a result, PiggingovThe slugs often form because the flow is blocked or the pipe content is pushed in front of the device. Unlike other cases of slug formation, which are periodic, this type is induced.
Slugcatcher proposals differ depending on the needs of the device, but there are three basic categories. The Slugcatcher type of container is generally a simple storage container, which also allows the separation of gas and liquid phases. Slumcatcher with multiple pipes can be implemented from standard pipe material and has a high flexibility in solving a wide range of streams. In Slugcatcher Parking loops are departments and storage different elements. The separator can be a type of vessel, while the storage part is a pipe loop located at a distance.
