“…Hydrotreating is a process in which the feed stream, practically any fraction of the oil, reacts with hydrogen at high pressures and temperatures in the presence of a heterogeneous catalyst (Korsten and Hoffmann, 1996;Murali et al, 2007). According to Aye and Zhang (2005) and Ferreira et al (2013), kinetic models are fundamental for a good performance of the HDT simulation, and the optimization of the hydrotreatment process can benefit from reliable kinetic models of the hydrodesulfurization reactions, among others.…”

The presence of contaminants in diesel oil is severely controlled. These components affect the diesel properties, causing impacts on the emissions of pollutants and compromising its commercialization. The Brazilian legislation imposes the use of diesel S10. In this work, a hydrotreatment unit fed with multiple diesel streams was optimized using a phenomenological mathematical model. A three-phase model of a tricked-bed reactor was considered. The optimization of the process was performed with the interior point method considering the hydrodesulfurization reaction of diesel. It was proposed to minimize the operating cost, keeping the amount of sulfur in the final product below the maximum allowed value. The EMSO process simulator was used to model, simulate and optimize the hydrotreatment process. It was observed that the optimization strategy drove the contaminant content into the diesel S10 specification range, as well as reducing the process operating cost by increasing the feed temperature and hydrogen flowrate and adjusting the feed composition blend of the available diesel streams.

“…O HDT de diesel é feito com o uso de um reator de leito gotejante (Trickle Bed Reactor -TBR) que permite a redução do teor de enxofre e de outros contaminantes. Desta forma, as correntes de óleo diesel a ser hidrotratado e de hidrogênio fluem através de um leito fixo de catalisador (Murali et al, 2007).…”

RESUMO -A presença de contaminantes no óleo diesel é severamente controlada. Estes componentes afetam as propriedades do diesel, causando impactos nas emissões de poluentes e comprometendo sua comercialização. A legislação impõe o uso de diesel mais puro, como o diesel S10. Este trabalho aborda a modelagem fenomenológica e controle avançado do processo de hidrotratamento de diesel, tendo como base mecanismos existentes na literatura. Na representação do processo foi considerado um modelo dinâmico trifásico de um reator de leito gotejante. Uma estratégia de controle preditivo baseada em modelo (MPC) foi implementada com o objetivo de controlar a concentração de enxofre na saída do reator, manipulando a vazão de líquido na carga, na presença de distúrbios na vazão de hidrogênio. Observou-se que a estratégia de controle levou o teor de contaminante para dentro da faixa de especificação do diesel S10.
