| Abstract: | In allusion to resolve corrosion problems of the main tar vacuum distillation tower′s exhaust equipment and pipelines in Henan Kaitan New Material Co.，Ltd.，the atmospheric distillation without alkali distillation mechanism was studied，and then the cause of the devices′s corrosion were found.By adding a super centrifuge，the technology of organic combinations of existing storage tanks and super-centrifuge were used.The pretreatment transformation of tar refining was completed.On the basis of the transformation，the operating parameters of the whole tar processing technology were optimized and the process management wad strengthened.Overall，corrosion problems had been fundamentally resolved，and then the system′s long-term operation had been ensured.Economic and environmental benefits were obvious. |
