Slugging refers to the irregular two-phase flow of both gas and liquids in a gas pipeline. Slug flow can create serious issues in gas pipelines and facilities including severe damage from mechanical vibrations, reduced production and even forced shut down of separators and compressor stations. As a result, having the capability to handle and mitigate the issues created by liquid slugs should always be a high priority in gas pipeline and facility design considerations.
Vessel-Type Slug Catcher
Spitzer’s Slug Catchers are designed in both the Two-Phase and Three-Phase variations. Both variations are in the most economically feasible way to handle the two-phase gas-liquid slugs. For many applications a vessel-type slug catcher is enough to capture and process, or work off the slug, without causing an upset at the facility. In this application the slug catcher works as a simple separator, with sufficient space to hold the liquid slug while still allowing gas volumes to pass unrestricted in the upper section of the vessel.
Finger-Type (Harp) Slug Catcher
When liquid volumes become sufficiently large, it becomes more economical feasible to use the Finger-Type slug catcher, this is due to the thinner wall requirements for the smaller diameter pipe or fingers. In addition, the manifold style of a Finger-Type slug catcher allows for easy addition of additional pipe should more capacity be needed in the future.
