Understand the future of oil production with this comprehensive guide
Heavy oil, also known as viscous oil, is oil too viscous to flow normally from wells and reservoirs. In recent decades it has become increasingly important as a source of liquid oil for use in industrial processes. This places all the greater importance on proper analysis of heavy oil and its properties, so that it can be more effectively refined and deployed to meet ever-growing energy needs.
Handbook of Heavy Oil Properties and Analysis provides a comprehensive introduction to the analysis of viscous oil and its properties. It discusses the full range of tests and analytical procedures by which the behavior and refinability of viscous oil samples can be predicted and connects theoretical knowledge to refinery practice throughout. Additionally, its incorporation of the latest environmental regulations makes it an invaluable resource.
Readers will also find: - Detailed coverage of both physical properties and chemical composition of heavy oil - An author more than fifty years of experience in the process industries - Discussion of new methods for determining instability and incompatibility
This book is a useful reference for scientists and engineers in the oil refining industries, chemists and researchers in heavy oil and adjacent industries, and government officials and regulators.
