Corrosion in the oil, gas and petrochemical industry and its preventive methods

Corrosion is one of the major problems facing the oil, gas and petrochemical industry, which is costly to deal with. Corrosion is effective on the life of the equipment, its exploitation, the return on capital, the quality of the products manufactured, and so on. The industry can include condensate wells, sweet oil wells, sour oil wells, offshore platforms (drilling), transportation and maintenance, refining operations, and others that recognizing these environments and the corrosion rate of these environments can help to control corrosion In the equipment. The higher temperatures and pressures usually cause more severe corrosion conditions. Corrosion control agents include: material selection ,Change in corrosive condition or corrosive material , Change in environmental conditions such as temperature, pressure and ... , Design changes , Use of corrosion inhibitors , Use of protective coatings , Use of cathodic protection and use of anode protection. In this paper, it has been tried to introduce the types of corrosion in the oil, gas and petrochemical industry, identification methods and mechanisms for their creation, and provide appropriate solutions to prevent these corrosion.
