CFD study - Finger Type Slug Catcher - Kranji Solutions

This movie shows a Computational Fluid Dynamics simulation of a Finger Type Slug Catcher . The Finger Type Slug Catcher shown is the existing mal-performing design. For more CFD troubleshooting information see also http://kranjisolutions.com. An American Oil and Gas company requested Kranji Solutions to perform a CFD simulation of their troubled Finger Type Slug Catcher. During pigging of the gas pipe line an extensive amount of liquids is travelling towards their gas plant. The storage volume of the collection fingers should be large enough to cope with the massive slugs entering this Finger Type Slug Catcher. Nevertheless, when the slug reached this equipment an unbalance was detected between the right-hand side and the left-hand side fingers, causing liquid level alarms, often followed by a complete plant trip. Upon discussions with the end-user, an exact 3D model of the Finger Type Slug Catcher was prepared. The arriving slug was modelled in the transient Eulerian 2-phase simulation. A User Defined Function (UDF) was used to incorporate the dynamic behaviour of the slug at the inlet of the model. The CFD analysis of the Existing Finger Type Slug Catcher revealed that the incoming liquids had a preferential flow path caused by the unfavourable inlet piping. More than 97% of the liquids entered the left-hand side of the Slug Catcher, while the right side only ended up with less then 3% liquid. This extreme unbalance caused several issues including the related liquid level alarms and plant trips. Upon discussions with the end-user, improvements were suggested and modelled. The CFD analysis of the improved design, with altered inlet piping and additional equalization line, showed far better distribution of the fluids. After submittal of the conclusive CFD results, the end-user modified the Finger Type Slug Catcher in accordance with the improvements suggested, which resolved all issues. CFD ANALYSIS BY KRANJI SOLUTIONS: In addition to many applications outside the process industry, for upstream, midstream and downstream Oil & Gas, CFD is an invaluable tool. It offers understanding of phase-interactions and quantifying velocities, forces and phase behaviour in complex flow systems.- Kranji Solutions has over 20 years’ experience assisting service companies and leading process operators to remedy process operation failures and constraints on production. Applying our industry knowledge and modelling skills we also develop unique equipment for our customers where they have challenging production and processing requirements involving 2-, 3- and 4-phase flows. TROUBLESHOOTING AND ANALYSIS. Using CFD in combination with MySep separator modelling software (www.mysep.com), or heat exchanger and process modelling, Kranji provides insight into the root cause of malperformance. Our specialisation in the application of CFD to internal flows, where phase-interaction is key to equipment performance, has resulted in a unique skill profile which has brought us success in assisting Oil & Gas customers world-wide. Our main application areas include: • Phase-separation • Heat transfer • Multi-phase flow dynamics • Impact of motion on performance (FPSO’s) • Erosion • Flow induced vibrations VALIDATION OF REMEDIAL MEASURES Having identified the causes of sub-optimal performance or operational failure, Kranji has deep experience of defining practical industry remedies. This may involve developing modifications to a unique flow system or entail recommending a range of vendors supplying suitable equipment. CFD modelling provides the client with confidence that process requirements can be met with a retro-fit or new-build solution. Design and Equipment Development We also undertake product development of proprietary equipment for customers. Sometimes this type of contract research involves CFD coupled with experimental test and validation using our in-house laboratory facilities and extensive research experience. BENEFITS OF CFD Whether the concern is mal-performance of existing operations or challenging new operational requirements, Kranji Solutions expert CFD modelling services allows our clients to: • Diagnose the root cause of mal performance or equipment failure • Verify the suitability of equipment designs before they are built • Optimise capital investment • Minimise risk of under-performance or down-time • Reducing project cycle time For more information please check http://kranjisolutions.com or email to [email protected].
