Information necessary to solve scientific or engineering problems is often so vast, that the need arises to lump information together into a more manageable subset in order to proceed. The idea of lumping is one which is used, more or less consciously, in a large variety of fields. The thermodynamics and kinetic behavior of multicomponent mixtures is an area where the requirements of lumping have been clearly identified and the techniques and results of lumping have been analyzed in considerable detail. This book comprises the proceedings of a Symposium on Kinetic and Thermodynamic Lumping of Multicomponent Mixtures which was held at the American Chemical Society Meeting in Atlanta, GA, in April 1991. Papers presented at the symposium consisted of both invited and contributed papers. Each invited paper was a review of a subfield within the landscape of the symposium while the contributed papers contain detailed analyses of specific problems. The symposium brought together active researchers in this field to report on and discuss the progress which has been made in the lumping of mixtures of very many components for a number of different applications, and to identify the important problem areas which still remain. This volume will serve both as an introduction to anyone entering the field, and as a reference work for more experienced researchers.

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.

Chemical processes in many fields of science and technology, including combustion, atmospheric chemistry, environmental modelling, process engineering, and systems biology, can be described by detailed reaction mechanisms consisting of numerous reaction steps. This book describes methods for the analysis of reaction mechanisms that are applicable in all these fields. Topics addressed include: how sensitivity and uncertainty analyses allow the calculation of the overall uncertainty of simulation results and the identification of the most important input parameters, the ways in which mechanisms can be reduced without losing important kinetic and dynamic detail, and the application of reduced models for more accurate engineering optimizations. This monograph is invaluable for researchers and engineers dealing with detailed reaction mechanisms, but is also useful for graduate students of related courses in chemistry, mechanical engineering, energy and environmental science and biology.

Process Engineering, the science and art of transforming rawmaterials and energy into a vast array of commercial materials, wasconceived at the end of the 19th Century. Its history in the roleof the Process Industries has been quite honorable, and techniquesand products have contributed to improve health, welfare andquality of life. Today, industrial enterprises, which are still amajor source of wealth, have to deal with new challenges in aglobal world. They need to reconsider their strategy taking intoaccount environmental constraints, social requirements, profit,competition, and resource depletion. “Systems thinking” is a prerequisite from processdevelopment at the lab level to good project management. Newmanufacturing concepts have to be considered, taking into accountLCA, supply chain management, recycling, plant flexibility,continuous development, process intensification andinnovation. This book combines experience from academia and industry in thefield of industrialization, i.e. in all processes involved in theconversion of research into successful operations. Enterprises arefacing major challenges in a world of fierce competition andglobalization. Process engineering techniques provide ProcessIndustries with the necessary tools to cope with these issues. Thechapters of this book give a new approach to the management oftechnology, projects and manufacturing. Contents Part 1: The Company as of Today 1.
