Multiobjective Optimization of a Hydrodesulfurization

2019-3-13·In distillation systems, steam is used either for heating purposes, indirectly in reboilers, or as a direct stripping agent in so-called steam-distillations, such as crude oil units. The flame temperature is lower in a boiler than in a furnace because the heat of combustion is removed immediately from the steam.
