CAUSE ANALYSIS AND PROCESS OPTIMIZATION ON CORROSION OF PROPANE DEASPHALTING UNIT |
| |
| Abstract: | Corrosion situation of propane deasphalting unit was described. Corrosion causes were analyzed. Desulfurization limitation of the alkali liquor from gas phase propane was sum-marized. Solved project was put forth on desulfurization process flow by adding liquid phase MDEA solution. Corrosion problem in the main equipments and pipelines caused by hydrogen sulfide was solved by the fore mentioned project, which ensured safe and stable running of the unit. |
