| Abstract: | The CO2 absorber for ammonia plant in Chongqing Jianfeng Chemical Fertilizer Co., Ltd. was serious corroded on the lower barrel. To repair the equipment, first we made an added welding on its inner wall, then we replaced the corroded barrel and painted an anti-corrosive coatings (1591) on its inner wall to increase its resistance to corrosion and abrasion. Reasons for corrosion were analyzed. It is suggested that aqueous alkali and liquid brushing are the main factors for erosion of metal material. Aimed at the corrosion reasons, anti-corrosion measures were presented accordingly. |
