The Study of Molecular Modeling for Heavy Oil Thermal Cracking

Abstract: The tighter specifications for refining products have gradually led refineries to focus on the molecular modeling of petroleum processing. In this work, a systematic methodology is presented for the molecular modeling of heavy oil thermal cracking (HOTC). This research which is based on a microscopic understanding provides a basis to achieve better design, management, optimization, and control of HOTC. The molecular information of HOTC product streams is represented in the form of a MTHS (molecular type homolo… Show more

“…The satisfactory accordance demonstrates that the proposed methodology in present study is of sufficient accuracy to characterize specific interaction between CO2 and functional groups of polymeric chain. This study demonstrates that the findings of atomistic behaviour at a microscopic scale can be extended to extrapolation of material properties applied to new applications and operation windows at a macroscopic level [114][115][116], which emphasizes the importance of molecular modelling in present study.…”

“…For instance, Peng et al [17] proposed an approach to represent a complex mixture based on a molecular-type homologous series (MTHS) with homologous and carbon number. Subsequently, Yan et al [18] incorporated the matrix into a heavy oil system and built a molecular model for the thermal cracking of heavy oil, which yields good results. In addition, two different algorithms were developed by Hudebine et al [19] to generate a complex mixture of molecules from standardized petroleum analyses: a stochastic reconstruction technique and a reconstruction by information entropy maximization.…”

“…Estes lumps podem ser classificados de acordo com seu ponto de ebulição, solubilidade etc(RADMANESH et al, 2008).O êxito do modelo depende da escolha do número de lumps, logo o maior número de lumps resulta em predições mais exatas(YAN et al, 2007).Com base nas variações das propriedades térmicas (em maior parte o ponto de ebulição) nestes componentes, os modelos cinéticos de lumps têm sido propostos. Os modelos mencionados podem ser categorizados entre (i) modelos de reação paralela (ii) modelos de reação paralelos -consecutivos.…”

“…Os modelos mencionados podem ser categorizados entre (i) modelos de reação paralela (ii) modelos de reação paralelos -consecutivos. As Tabela 3.1 e 3.2 mostram estas categorias respectivamente(KATARIA et al, 2003).A principal diferença entre estes é que o produto formado no modelo paraleloconsecutivo poderia sofrer craqueamento térmico adicional(YAN et al, 2007).…”
