| Abstract: | An analysis was made of the corrosion shapes and corrosion products of the components of the hydrogenation reactors of the PTA plants for their stress corrosion problems in high temperature and alkali environments using the optical microscope and EDS instruments,and the value and distribution of the heat stress were obtained through ANSYS software,the major factors of forming alkali corrosion and mutual effect were derived,and some corresponding preventions and improvements were proposed. |
