Corrosion Protection of Pipe Steel in Petroleum Gas Preparation and Drying Equipment

  • MATERIALS SCIENCE AND CORROSION PROTECTION

Chemical and Petroleum Engineering Aims and scope

Corrosion resistance of 09G2S steel in a moving model environment of formation water of the Kharyaga oilfield and in a moist hydrogen sulfide-containing atmosphere that simulate the chemical composition of the technological environment in petroleum gas preparation and drying is investigated. Introduction of inhibitors Olazol Т2P, Olazol 26501, Telaz and IKB2–2 into the model environments reduces the corrosion rate of the investigated steel from 3.34 to 0.37 g/(m2·hr). In a moist hydrogen sulfide-containing atmosphere, coating of steel surface in inhibitor film increases the time to appearance of corrosion damage. After 30 days of testing, the surface of steel without an inhibitor film is entirely covered in corrosion products, and under the inhibitor film the corrosion damage area is much smaller. The obtained results indicate that effective protection of steel of petroleum gas preparation and drying equipment is possible using the studied inhibitors.
