Description
Book SynopsisComprehensively covers the engineering aspects of corrosion and materials in hydrocarbon production
This book captures the current understanding of corrosion processes in upstream operations and provides a brief overview of parameters and measures needed for optimum design of facilities. It focuses on internal corrosion occurring in hydrocarbon production environments and the key issues affecting its occurrence, including: the types and morphology of corrosion damage; principal metallic materials deployed; and mitigating measures to optimise its occurrence. The book also highlights important areas of progress and challenges, and looks toward the future of research and development to enable improved and economical design of facilities for oil and a gas production.
Written for both those familiar and unfamiliar with the subjectand by two authors with more than 60 years combined industry experiencethis book covers everything from Corrosion Resistant Alloys (CRAs) t
