Computational Fluid Dynamics

Rhine Ruhr’s many years of practical experience coupled with client feedback of actual plant separation performance has resulted in reliable design correlations for the design of our range of separation internals.

The challenge to constantly improve our equipment separation capability has been made possible through the additional use of Computational Fluid Dynamics (CFD) analysis utilizing plant performance data.

CFD analysis is a powerful tool that provides a three-dimensional analysis of the fluid flow characteristics over time. Engineers at Rhine Ruhr investigate various characteristics of the client proposed vessel including gas side flow patterns, expected particle flow patterns and conditions at the inlet and outlet nozzles.

This information, combined with the CFD analysis results of our specialised equipment, provides confidence in the initial design or allows for recommendations to be made to improve separation capacity. Changes to equipment geometries or alternative equipment selection may eventually be needed to accommodate for upset conditions or future upgrades. CFD analysis can be used to improve equipment selection in installations that our clients deem as sensitive or critical.

An added benefit is our ability to interface various output from the CFD models with Finite Element Analysis (FEA) software in order to examine the mechanical reliability of the proposed equipment installation. This allows us to investigate the mechanical stress on the separation equipment caused by a liquid slug or developed by the mechanical support arrangement inside the vessel.
