Modeling and Simulation of Catalytic Reactors for Petroleum Refining

Modeling and Simulation of Catalytic Reactors for Petroleum Refining

Jorge Ancheyta

John Wiley Sons Inc
2011
sidottu
Modeling and Simulation of Catalytic Reactors for Petroleum Refining deals with fundamental descriptions of the main conversion processes employed in the petroleum refining industry: catalytic hydrotreating, catalytic reforming, and fluid catalytic cracking. Common approaches for modeling of catalytic reactors for steady-state and dynamic simulations are also described and analyzed. Aspects such as thermodynamics, reaction kinetics, process variables, process scheme, and reactor design are discussed in detail from both research and commercial points of view. Results of simulation with the developed models are compared with those determined at pilot plant scale as well as commercial practice. Kinetics data used in the reactor model are either taken from the literature or obtained under controlled experiments at the laboratory.

Modeling of Processes and Reactors for Upgrading of Heavy Petroleum

Modeling of Processes and Reactors for Upgrading of Heavy Petroleum

Jorge Ancheyta

CRC Press Inc
2013
sidottu
The worldwide petroleum industry is facing a dilemma: the production level of heavy petroleum is higher than that of light petroleum. Heavy crude oils possess high amounts of impurities (sulfur, nitrogen, metals, and asphaltenes), as well as a high yield of residue with consequent low production of valuable distillates (gasoline and diesel). These characteristics, in turn, are responsible for the low price of heavy petroleum. Additionally, existing refineries are designed to process light crude oil, and heavy oil cannot be refined to 100 percent. One solution to this problem is the installation of plants for heavy oil upgrading before sending this raw material to a refinery. Modeling of Processes and Reactors for Upgrading of Heavy Petroleum gives an up-to-date treatment of modeling of reactors employed in the main processes for heavy petroleum upgrading. The book includes fundamental aspects such as thermodynamics, reaction kinetics, chemistry, and process variables. Process schemes for each process are discussed in detail. The author thoroughly describes the development of correlations, reactor models, and kinetic models with the aid of experimental data collected from different reaction scales. The validation of modeling results is performed by comparison with experimental and commercial data taken from the literature or generated in various laboratory scale reactors. Organized into three sections, this book deals with general aspects of properties and upgrading of heavy oils, describes the modeling of non-catalytic processes, as well as the modeling of catalytic processes. Each chapter provides detailed experimental data, explanations of how to determine model parameters, and comparisons with reactor model predictions for different situations, so that readers can adapt their own computer programs. The book includes rigorous treatment of the different topics as well as the step-by-step description of model formulation and application. It is not only an indispensable reference for professionals working in the development of reactor models for the petroleum industry, but also a textbook for full courses in chemical reaction engineering.The author would like to express his sincere appreciation to the Marcos Moshinsky Foundation for the financial support provided by means of a Cátedra de Investigación.

During the upgrading of heavy petroleum, asphaltene is the most problematic impurity since it is the main cause of catalyst deactivation and sediments formation. Exploring many aspects related to asphaltenes composition and conversion, Asphaltenes: Chemical Transformation during Hydroprocessing of Heavy Oils highlights the various changes that these heavy and complex molecules undergo during catalytic hydroprocessing. After defining and characterizing asphaltene structure, the book examines the composition of petroleum and the processes and catalysts for upgrading heavy oils. It then details the characterization of asphaltenes after hydroprocessing and the effect of reaction conditions on their structures. The authors also analyze the deactivation and characterization of spent hydroprocessing catalysts as well as the role played by asphaltenes. They cover sediments formation during hydroprocessing and the role of asphaltenes on it. The final chapters describe the hydrocracking and kinetics of asphaltenes and the fractionation of heavy crudes and asphaltenes.Due to the increasing production of heavy crude oils, asphaltene has become one of the most studied molecules. This book provides a deep understanding of how asphaltenes transform during hydroprocessing, offering insight on designing catalysts and processing for the upgrading of heavy oils.

Jorge Luis Borges

Ilan Stavans

OXFORD UNIVERSITY PRESS INC

Jorge Luis Borges (1899--1986) is one of the most influential literary figures of the twentieth century. His short stories, poems, essays, and translations explore Argentine mythology, mysticism, philosophical ideas, and myriad other topics. This Very Short Introduction gives an engaging overview of Borges's life and the major themes of his oeuvre. Ilan Stavans places Borges in the context of tango and gaucho literature and follows his transformation into an explorer of time and metaphysical dimensions across cultures. As an inveterate reader of Cervantes, Shakespeare, Flaubert, Coleridge, and The Arabian Nights, Borges has become closely associated with the book as an object of knowledge and of the imagination. Stavans demonstrates how Borges's evolution as a writer allowed him to revolutionize contemporary literature and thought in fundamental ways through such works as Ficciones, Other Inquisitions, and Labyrinths, and shows how his career redefined Latin American as well as global literature.

Jorge Luis Borges, Post-Analytic Philosophy, and Representation

Jorge Luis Borges, Post-Analytic Philosophy, and Representation

Silvia G. Dapía

Routledge
2019
nidottu
Making an important contribution to studies in Literature and Philosophy, this book reads Jorge Luis Borges philosophically, particularly in reference to his use of representation and reality. Rather than attempting to subordinate Borges to a set of philosophical constructs, to reduce Borges’ texts to mere exemplifications or illustrations of philosophical theories, the book uses Borges’s short stories to demonstrate how philosophical questions related to representation develop out of literature and actually serve as precursors to the various strains of post-analytic philosophy that later developed in the United States. The volume discusses American post-analytic philosophers Richard Rorty, Hilary Putnam, Donald Davidson, Nelson Goodman, and Arthur Danto, as well as a wide-ranging set of philosophical ideas including reflections on Keynes, Hayek, Schopenhauer and many others . Chapters offer detailed readings of Borges’ texts extending from 1939 to 1983, locating where he thematizes issues of representation, and pursuing the logic of Borges’s text toward its philosophical implications without neglecting their literary value. The book argues that Borges’ exploration of the relationship between representation and reality places him unmistakably in the position of a precursor to the post-analytic philosophers. Illuminating the role that language plays in the creation of reality and representation, this volume makes significant contributions not only to Borges scholarship but also post-structuralism, post-analytic studies of language, semiotics, comparative literature, and Latin American literature.
