Current status of corrosion simulation in plant engineering is reviewed. As a result, it is shown that corrosion simulation is used for evaluation of corrosion resistance of materials, study of corrosiveness by change in operation parameter and identification of highly corrosive locations. In addition, an example of application of corrosion simulator for gas production facility which handles corrosive media such as hydrogen sulfide and carbon dioxide is introduced. As are result, it is indicated that calculated results are different between simulators due to difference in input parameters or calculation algorithm. Through the study, it is suggested that corrosion simulation is a powerful tool but knowledge and special consideration on corrosion phenomenon are required for engineers who use it.
