Title
Simulation of hydrotreating of light cycle oil with a system dynamics model
Abstract

To serve as a diesel fraction, light cycle oil (LCO) is commonly hydrotreated by a complicated and widely used industrial process under high temperature and high pressure. In this study, the system dynamics (SD) methodology is, for the first time, introduced to dynamically simulate this commercial hydratreating process along the axial positions of the hydrotreator. The proposed SD model is fully presented and validated by both direct and indirect structure validation tests. The efficiencies of the hydrodesulphurization (HDS), hydrodenitrogenation (HDN), and hydrodearomatization (HDA), and the consumption rate of H2 gas during the hydrotreating process are also simulated. The influence of the operating conditions such as the liquid hourly space velocity (LHSV) and the inlet feed temperature on these efficiencies and H2 consumption is investigated numerically.
