| Abstract: |
| In allusion to corrosion damage effects of crude oil refining on equipment and pipeline, source, formation mechanism and corrosion mechanism of elemental sulfur, hydrogen sulfide, naphthenic acid and HCl + H2S + H2O system were analyzed; situations of sulfur, salt and acid content in processing crude oil of the seven eastern petrochemical enterprises were introduced. According to the oil refining process, corrosion and control situations of main equipment and pipeline in crude oil desalting and dewatering, atmospheric and vacuum distillation, catalytic cracking, hydrocracking, delayed coking, and other process were compared respectively; direction of research and application in this respect for the oil refining enterprises and related research institutions was proposed. |
