چکیده

Annually, huge amount of money is lost due to corrosion problems in upstream and downstream oil and gas industries. In order to control the corrosion costs, recently, the corrosion control/corrosion management concept is developed. The aim of corrosion management philosophy is to reduce the corrosion costs and increase the safety by re-evaluation process in different stages of the project. Material selection process is one of key stages in integration assurance of the system, which plays important role in overall corrosion control process. Some important parameters in selecting suitable materials for using in a given working and environmental condition includes: design pressure and temperature, weldability, costs and corrosion concerns. Nowadays, the last one attracted attentions of the both researchers and owners. Codes like ISO ۲۱۴۵۷ necessitate providing Material Selection Procedure Report before proceeding executive steps of the project. Without any specific material selection procedure; the material selection process will be a complex and confusing task because of the diversity in codes and fluid service conditions. The aim of this study is to introduce researchers and engineering with corrosion concerns especially in CO۲, H۲S and salt contained services and the solutions which are normally employed in upstream oil industry to deal with associated problems. Towards, environmental deterioration problems in Iranian oil and gas fields are discussed and the related treatments are presented.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
