| Abstract: | The causes of corrosion of the bottom reboiler of solvent regenerator in a gas desulfurization unit were analyzed. The carbon dioxide in the solvent, inappropriate equipment construction and erosion were the major factors resulting in corrosion. The corrosion prevention measures, including equipment construction retrofit, upgrading materials, solvent purification and process condition optimization were proposed. Good results have been obtained. |
