Asphaltene Deposition Control by Chemical Inhibitors: Theoretical and Practical Prospects is the most advanced reference focused on chemical dispersants and inhibitors from both an experimental and modeling viewpoint. Adequate knowledge of the effective parameters in each treatment method, interactions, mechanisms and economic viewpoints involved in asphaltene treatment are crucial for future development, recovery forecast, and reserve prediction, hence this reference delivers on all these aspects. Sections cover the environmental impacts of asphaltene deposition, prevention methods, and experimental methods, both static and dynamic, to test the effectiveness of inhibitors on restricting asphaltene deposition. Rounding out with modeling methods used to simulate asphaltene-inhibitor interactions and a workflow to select suitable inhibitors by technical, economic and environmental considerations, this book will give today's engineers and researchers the right tool to mitigate formation damage in a sustainably responsible way. - Focuses on inhibitors, mitigators and the interplay between the asphaltene-inhibitors - Helps readers learn from experimental models and replicate treatments with screening workflows - Includes case studies that help readers make sustainable and economically-sound decisions on treatments

Asphaltenes are non-crystalline, brittle, and black solids. At high temperatures they can polymerize, and convert into coke or asphaltic residue. As they do not show a fixed boiling point temperature, it is impossible to measure their enthalpy of vaporization by direct means. This book provides current research on the fundamentals, applications and future developments of asphaltenes. Chapter One presents an overview of the main properties of the crude oil (crude) asphaltenes, the problems that these dimly-understood solubility class of chemical compounds may create during the production, transportation and refining processes, and the recent efforts that have been made to achieve a more comprehensive understanding of the molecular architecture and aggregation mechanisms presented by these compounds. Chapter Two examines asphaltenes and crude oil fouling. Chapter Three reviews thermal degradation of asphaltene by Micro Scale Sealed Vessel (MSSV) pyrolysis. Chapter Four aims to develop magnetite-silica nanoparticles with a core-shell structure to inhibit the formation damage caused by asphaltenes. Chapter Five evaluates surface changes in CAP 30/45 (asphalt cement, penetration grade 30/45) and paraffin films obtained through spin coating and aged by ultraviolet (UV) irradiation. Chapter Six investigates the factors that affect the breakthrough time process of CO2 injection, using a 2D mathematical model for immiscible injection of carbon dioxide which was developed in the formation of Ilam in one of the oil fields in Iran.

Asphaltenes are molecular substances that are found in crude oil, along with resins, aromatic hydrocarbons, and alkanes (i.e., saturated hydrocarbons). Asphaltenes in the form of distillation products from oil refineries are used as'tar-mats'on roads. This new book discusses the characterization of alphaltenes and crude oils using near-UV/visible absorption spectroscopy. An overview of alphaltenes in petroleum and the cause of sediment deposition during production and refining is examined as well as the effects of magnetic fields on the paramagnetic, antioxidant, and viscous properties of oils and resin-alphaltene components. Insights into the structural characteristics of asphaltenes and its geochemical significance is also discussed.

This is the second volume in the series of Asphaltenes and Asphalts. Since the publication of the first volume in 1994, there has been a significant advancement in our knowledge. Knowledge of both asphaltenes and asphalts is needed by several disciplines, and often the progress is dictated by interdisciplinary sciences and technology. This includes material sciences, fuel sciences, chemical engineering, civil engineering, environmental engineering, polymer sciences, transportation engineering, petroleum engineering, chemistry, geological sciences, physics, geochemistry rheology, biological sciences, tribology, soil sciences, petroleum science. The development in this field is not based on our knowledge of chemistry or petroleum engineering alone, as many chemists and petroleum engineers believe. In this volume, therefore, significant contributions from different disciplines have been included.

This is the first volume of a two-volume set of critical reviews of many aspects of both asphaltenes and asphalts and their interrelationship. Asphaltene is invariably present in asphalt or bitumen and other fossil fuel-derived liquids such as coal tar, coal liquefaction products, pyrolyzed shale oil from oil shales, source rock extracts and numerous naturally occurring bituminous substances. The latter include asphaltites, asphaltoids, waxes, and carbonaceous deposits containing a composition of petroleum and coal.The contents cover not only the basic science of asphaltene but also deal with the applications and technology such as upstreams (production, recovery) and down streams (refining, upgrading) of petroleum, and the paving technology and formulation preparation. The main features of the book are: it provides an up-to-date, in-depth review of every aspect of asphaltenes and asphalts; it spans five decades of research and technology of heavy fractions of petroleum; it presents a global view of asphaltene related to exploration production, refining and upgrading.The book will be welcomed as a valuable reference source for petroleum companies, research institutes, refineries, universities and also by individuals dealing with the production, origin, formation, engineering, conversion and catalysis of heavy oil, tar sands and other bitumens materials.
