Abstract A thermodynamic analysis on the characteristics of iron/naphthenic acid/hydrogen sulfide ocrrosion system is presented.The results indicate that the corrosion products of this system are dependent on the partial pressures of hydrogen sulfide and naphthenic acid.In the passivation region,the diffusion process of sulfide in the surficial layer is the rate-determining step of corrosion.In the corrosion region,however,the corrosion rate is controlled by the reaction process of naphthenic acid on iron surface.And corrosion of iron can only occur when the partial pressure exceeds a critical value.On the basis of the phase diagrams,the reasons for the appearance of two peaks of corrosion rate with the change of temperature are discussed.It could be attributed to the formation and the decomposition of active sulfides.

Key words: naphthenic acid hydrogen sulfide diagram
