| dc.description.abstract | Removal of sulphur from fossil fuels is important in order to avoid the emission of sulphur oxides into the atmosphere, exposure to which has negative health and environ- mental effects. Sulphur is removed from refinery petrochemical products via the Claus process which contains a waste heat boiler (WHB). These WHBs are exposed to extreme temperatures and corrosive conditions, yet they are expected to operate continuously for years at a time. Typically WHBs have been designed using empirical correlations and heuristics, but more recently using process and multiphysics simulation. In this work a proof of concept for the numerical simulation of a WHB and its protective insulation is demonstrated. Continuum multiphysics models for both shell and tube side of a WHB are developed. An iterative coupling method for the determination of steady-state numerical solution of these models is then used to simulate a sub-region of a typical WHB. Simulation results for the tube-side of the WHB predict both the temperature profile and nature of the turbulent energy transport in the inlet region, highlighting complex flow profiles. Simulations of the shell-side of the WHB predict the multiphase convective boiling behaviour in the bulk (far from wall effects). Finally, preliminary results of the coupled shell/tube configurations are presented and compared to previous results. | en |
