Abstract
Embodiments of a Flow Conditioning System (“FCS”) of this disclosure may be used for homogenizing a fluid containing a gas phase and a liquid phase. In some embodiments the FCS may be applied to a fluid containing hydrocarbons. The FCS may be located where appropriate, including but not limited to subsea. The FCS may be used for homogenizing slug flow. In embodiments, the FCS may be composed of an outer shroud pipe section, into which a concentric perforated smaller pipe is inserted at the top. The inlet slug flow regime is changed at the shroud section whereby the slugs are broken, transitioning to well-mixed flow regimes, such as bubbly flow or continuous churn flow. The bubbly or continuous churn flow that occur in the shroud section are forced to pass through the perforations of the perforated smaller diameter pipe, which promote a more thorough mixing of the phases upstream of devices such as multiphase pumps.
