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 |
