| Abstract: | The equipment corrosion forms of hydroprocessing units in processing high-sulfur crude oils are described and corrosion mechanisms and harms are analyzed.The major culprits of corrosion of equipment are H_2,S,H_2S,NH_4HS and NH_4Cl,etc.The main corrosion forms are hydrogen attack,SSCC of austenitie stainless steel,temper embrittlement of Cr-Mo steel and corrosion of NH_4HS and NH_4Cl.The corrosions can be brought under control by proper selection of materials,good fabrication and installation,strict operation, necessary process corrosion protection and scheduled inspection and maintenance. |
