Stripping tower for the hydrogenation refining of gasoline, diesel, and kerosene in the petrochemical industry; tower material: SPV32 (a high-wear-resistant, high-strength alloy structural steel); medium: steam and oil gases; temperature: 150°C; pressure: 1.3 MPa. During use, corrosion occurred on the inner wall of the tower; rust deposits adhered to the surface of the tower, along with some grease and dirt. During maintenance, chemical cleaning was used to clean the inner wall of the tower, and the results were good.
In the petrochemical industry, chemical cleaning methods are used in stripping towers to effectively remove corrosion products and oil residues from within the tower, thereby ensuring the proper operation of the equipment and extending its service life. .
