Enhancement of Productivity of Distillate Fractions by Crude Oil Hydrotreatment: Development of Kinetic Model for the Hydrotreating Process

摘要

Crude oil hydrotreatment enhances the productivity of distillate fractions due to chemical reactions. A trickle bed reactor (TBR) is used in this work for hydrotreating (HDT) crude oil. In order to obtain a useful model for the reactor which can be confidently applied to design, operation and control, accurate estimation of kinetic parameters of the relevant reactions are required. A kinetic model for those chemical reactions is proposed here. An optimization technique is used to obtain the best values of the kinetic parameters based on pilot plant experiment. The predicted hydrotreated product composition shows very well agreement with the experimental data for a wide range of operating conditions with absolute average errors less than 5% and clearly shows enhancement of productivity of distillate fractions.
