چکیده:

A two-phase flow pipeline is intended for transporting the gas and liquid phases
simultaneously. There are different modes under which liquid can be produced from the
pipeline. These include: the continuous liquid flow production mode under normal steady
flow conditions; the intermittent or transient liquid production mode occurring when flow
rates are varied and the pigging or sphering mode when liquid is displaced within the
pipeline in a relatively short time. These occasionally very large volumes of liquids
encountered must be handled and stored as they emerge from the pipeline, preferably
without any reduction in velocity, which would be reflected in the gas production. For this
reason, a liquid-receiving facility known as a slug catcher is always connected to a twophase
pipeline. In this paper, rigorous modeling of multiple-pipe slug catcher based on
computational Fluid Dynamic (CFD) Calculations with ANSYS CFXTM is presented,
together with its application for debottlenecking of an existing multiple-pipe slug catcher.
