Corrosion Behaviors of L360 Steel in Vapor and Liquid Phases Containing H₂S/CO₂

The corrosion behavior of L360 steel in vapor and liquid phases containing H2S/CO2 was studied by dynamic weight loss method.The inhibition performance in liquid phase was studied by adding inhibitors.The results showed that as the temperature rised, the corrosion rate in vapor phase decreasd and in liquid phase increasd. As the partial pressure of H2S and CO2 increased, the corrosion rate in vapor and liquid phases both increased. The addition of inhibitors reduced greatly the corrosion rate.
