Experimental analysis and modeline of gasoil hydrotreatment process

Medde, Michela (2008) Experimental analysis and modeline of gasoil hydrotreatment process. [Doctoral Thesis]



Oil industry is continuously evolving chasing the fast development of the contrasting requirements of modern life. From one side, it tries to satisfy the growing energy demand adopting its production to provide the energy resources requred by the market while considering at the same time the increasing pressure to the environmental protection. For this reason, the increasing demand for diesel fuels coupled with the progressive tightening of environmental specifications has brought new emphasis on the research on gasoil production. Worldwide refineries, also in consideration of the varyng quality of the feedstock, are tryng to optimaze the current process operation to maximize the utilization of the available sources. Depending of the specific constraints, this is realizable through the construction of the new plants or the revamp of pre-existing units coupled to the utilization of state of the art catalysts. In any case, optimization of operating conditions is crucial. In this context, this thesis proposes a phenomenological model that could be used to optimize the operating conditions of hydroprocessing plants that, due to their hydrogenation, hydrodesulfurization and hydrodenitrogenation reactions, are the refinery plants devoted to the improvement of gasoil quality. In this way the optimization of the process can always guarantee the satisfaction of more critical specifications.
