Case Studies

Slug Catcher Flow Assurance

Gas production systems may operate in the "slug flow" multiphase regime in which large volumes of liquid are interspersed with the gas. Under these conditions, the arrival of the liquid slugs can be detrimental to separation performance and the mechanical stress levels are greatly increased. In the example shown below, Zeta-pdm was asked to analyse the failure of a slug catcher vessel. Inspection showed that the slugs had caused mechanical failure of the separation internals. Subsequently, a simulation study yielded a vastly improved understanding of the flow behaviour, enabling Zeta-pdm to recommend internals better able to withstand severe operating conditions.
