Understanding Heat Transfer and Complex Buoyancy-driven Circulation in Sulphur Condensers

Troubleshooting and Root Cause Failure Analysis (RCFA), of process equipment operations, is often hampered by an inability to measure all key quantities of interest. Frequently the only recourse is to utilise simulation techniques.  The ease of use and accuracy of Computational Fluid Dynamics (CFD) continues to improve, however, successful CFD modelling frequently requires supporting analysis from process simulation and other analytical software.

CFD Process-side Distribution

CFD modelling was conducted for the process side system to establish the magnitude and impact of tube side maldistribution in the condensers.  This was found to be modest and was demonstrated to have minimal impact on thermal behaviour

Shell-side volume vapour fraction iso-surfaces

CFD simulation of the shell side circulation system, including fully coupled heat transfer representation of both process side cooling and evaporation on the shell side was central to the studies.  This revealed disruption of liquid recirculation was occurring within the shells, attributed to the way BFW was distributed within the shell.
