This book provides an overview of the science and technology of organic solids formation, deposition, removal, and prevention, with emphasis on the basic chemical and mechanical principles of deposition control. Chapters describe the flow systems in which arterial deposits occur, place the technical aspects of deposition management in the perspective of the upstream oil and gas business, and address multiple aspects of organic deposits, including the chemical and physical driving forces for deposit formation, the methods for managing deposits, and the simulation tools that may be used to forecast the magnitude of potential problems.
