This book was released on 2013-01-29 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Catalysts for Upgrading Heavy Petroleum Feeds written by Edward Furimsky and published by Elsevier. This book was released on 2007-09-12 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides the most up-to-date information on testing and development of hydroprocessing catalysts with the aim to improve performance of the conventional and modified catalysts as well as to develop novel catalytic formulations. Besides diverse chemical composition, special attention is devoted to pore size and pore volume distribution of the catalysts. Properties of the catalysts are discussed in terms of their suitability for upgrading heavy feeds. For this purpose atmospheric residue was chosen as the base for defining other heavy feeds which comprise vacuum gas oil, deasphalted oil and vacuum residues in addition to topped heavy crude and bitumen. Attention is paid to deactivation with the aim to extent catalyst life during the operation. Into consideration is taken the loss of activity due to fouling, metal deposition, coke formed as the result of chemical reaction and poisoning by nitrogen bases. Mathematical models were reviewed focussing on those which can simulate performance of the commercial operations. Configurations of hydroprocessing reactors were compared in terms of their capability to upgrade various heavy feeds providing that a suitable catalyst was selected. Strategies for regeneration, utilization and disposal of spent hydroprocesing catalysts were evaluated. Potential of the non-conventional hydroprocessing involving soluble/dispersed catalysts and biocatalysts in comparison with conventional methods were assessed to identify issues which prevent commercial utilization of the former. A separate chapter is devoted to catalytic dewaxing because the structure of dewaxing catalysts is rather different than that of hydroprocessing catalysts, i.e., the objective of catalytic dewaxing is different than that of the conventional hydroprocessing, The relevant information in the scientific literature is complemented with the Patent literature covering the development of catalysts and novel reactor configurations.Separate chapter was added to distinguish upgrading capabilities of the residues catalytic cracking processes from those employing hydroprocessing. Upper limits on the content of carbon residue and metals in the feeds which can still be upgraded by the former processes differ markedly from those in the feeds which can be upgraded by hydroprocessing. It is necessary that the costs of modifications of catalytic cracking processes to accommodate heavier feeds are compared with that of hydroprocessing methods.Objective of the short chapter on upgrading by carbon rejecting processes was to identify limits of contaminants in heavy feeds beyond which catalytic upgrading via hydroprocessing becomes uneconomical because of the costs of catalyst inventory and that of reactors and equipment. - Comprehensive and most recent information on hydroprocessing catalysts for upgrading heavy petroleum feeds.- Compares conventional, modified and novel catalysts for upgrading a wide range of heavy petroleum feeds.- Comparison of conventional with non-conventional hydroprocessing, the latter involving soluble/dispersed catalysts and biocatalysts. - Development and comparison of mathematical models to simulate performance of catalytic reactors including most problematic feeds.- Residues upgrading by catalytic cracking in comparison to hydroprocessing.

This book was released on 2023-06-06 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalytic In-Situ Upgrading of Heavy and Extra-Heavy Crude Oils A comprehensive guide to a cutting-edge and cost-effective refinement process for heavy oil Oil sufficiently viscous that it cannot flow normally from production wells is called heavy oil and constitutes as much as 70% of global oil reserves. Extracting and refining this oil can pose significant challenges, including very high transportation costs. As a result, processes which produce and partially refine heavy oil in situ, known as catalytic upgrading, are an increasingly important part of the heavy oil extraction process, and the reduced carbon footprint associated with these methods promises to make them even more significant in the coming years. Catalytic In-Situ Upgrading of Heavy and Extra-Heavy Crude Oils provides a comprehensive introduction to these processes. It introduces the properties and characteristics of heavy and extra-heavy oil before discussing different catalysts and catalyzing processes, their mechanisms and underlying physics, and more. It offers the full sweep of description and analysis required for petroleum and chemical engineers to understand this vital aspect of the modern oil industry. Readers will also find: Detailed discussion of subjects including electron paramagnetic resonance spectroscopy, nuclear magnetic resonance spectroscopy, and more Analysis of both liquid catalysts and nanoparticle catalysts A numerical simulation of the catalytic in-situ oil upgrading process Catalytic In-Situ Upgrading of Heavy and Extra-Heavy Crude Oils is a valuable reference for petroleum and chemical engineers as well as advanced undergraduate and graduate students in related fields.

D.) and published by . This book was released on 2019 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercritical water heavy oil upgrading, which has the potential for high distillate liquid yields with lower coke formation, is a complex process involving coupled reactions, phase equilibrium and two-phase mixing phenomena. This thesis presents the development of a range of models and tools to simulate such processes at different scales with varying levels of fidelity in describing the underlying physical phenomena. Over the past decade, a number of experiments have been performed in batch reactors to study the upgrading of various heavy oils and crude oil vacuum residua through both oil-phase pyrolysis and reaction in the presence of supercritical water (SCW). While these studies indicate that the presence of SCW can significantly affect the outcomes of the upgrading process, there remains a lack of clarity on whether thermolytic processing in the presence of SCW is indeed significantly beneficial as opposed to pure oil phase pyrolysis and if so, at what operating conditions. In addition, modeling tools coupling the reaction kinetics and phase equilibrium, which can provide deeper insight into the process and the underlying phenomena have been lacking. The first part of this thesis describes the development and application of a two-phase stirred reactor (TPSR) model which couples sub-models for the phase-specific reaction kinetics and multi-component hydrocarbon-water phase equilibrium. Using this model, separate lumped kinetics rate parameters for the oil and SCW phases were inferred that best fit batch reactor experimental data. Analysis of the obtained kinetics parameters reveal the following crucial insights on the chemical pathways involved in the SCW upgrading process (i) the primary coke precursor formation pathway is not suppressed in the SCW phase and (ii) only the secondary pathway towards coke precursors from product distillate species is suppressed in the SCW phase, especially at higher operating temperatures. The TPSR model was then applied to evaluate the performance of heavy oil upgrading using SCW in an oil-water co-flow (visbreaking) Next, an extractive upgrading reactor design was hypothesized to improve high-value distillate liquid product yields and reduce undesirable extrinsic coke formation by removing the distillate products safely out of the reactor in a SCW up-flow thereby preventing their further participation in secondary retrograde combination reactions towards more aromatic coke precursors and low-value gas. The TPSR model was used to evaluate the performance of the SCW extractive upgrading process in terms of distillate liquid yields and coke formation rates for heavy oil vacuum residue over a range of operating temperatures and water flow rates. The predictions demonstrate the significant potential of the extractive upgrading process to achieve the aforementioned objectives. The effect of the extraction rate governed by the interphase mixing time-scale on the product yields and oil-inflow rate for steady-state operation was then quantified. The second part of the thesis describes the development of a computational fluid dynamics (CFD) framework and modeling tool for simulating the coupled two-phase flow and multi-component interphase mass transfer at near-critical/supercritical conditions in applications like SCW heavy oil upgrading. The CFD tool accounts for interface tracking in 2-D/3-D, intra-phase species diffusion, phase-equilibrium limited interphase species transfer and non-ideal thermodynamics. In this tool, the interface is tracked with a conservative sharp interface capturing Volume of Fluid (VoF) scheme using (i) a Piece-wise Linear Interface Reconstruction (PLIC) algorithm (ii) an unsplit geometrical advective flux calculation and (iii) a flux-polyhedron correction. The intra-phase species diffusion is handled using a corrected face-normal gradient calculation accounting for the arbitrary shape and size of phase-specific sub-cells. The interphase mass transfer is computed as a source term consistent with the local phase equilibrium and transport flux constraints at the interface. Finally, the phase-volume change is rigorously accounted for in the discrete pressure equation. The tool was implemented on an open-source CFD platform ensuring compatibility with unstructured mesh information and parallel processing constraints. Finally, the developed CFD tool was applied to determine the two-phase mixing rates in an extractive upgrading configuration for water flow rates of interest. The predictions suggest that the earlier assumption of instantaneous phase-equilibration with respect to the time-scale of reactions relevant in the SCW heavy-oil upgrading process is a reasonable approximation for centimeter-scale reactors. Furthermore, the scaling of the total oil-water interfacial area in the reactor and the average Sherwood number with the water inlet velocity and oil-water interfacial tension were established, providing insight into ways to manipulate the two-phase mixing rate to enable control of the extractive upgrading process at higher operating temperatures.
