摘要

Abstract

Computer simulation is a good guide and reference for development and research on petroleum refining processes. Traditionally

pseudo-components are used in the simulation

in which their physical properties are estimated by empirical relations and cannot be associated with actual chemical reactions

as nomolecular structure is available for pseudo-components. This limitation can be overcome if real components are used. In this paper

a real component based method is proposed for the simulation of a diesel hydrotreating process by using the software of Unisim Design. This process includes reaction units and distillation units. The chemical reaction network is established by analyzing the feedstock. The feedstock is characterized by real components

which are obtained based on true boiling point curve. Simulation results are consistent with actual data.
