As scientific and technological capabilities improve, various industries are placing increasing demands on the performance of production equipment. In particular, chemical processing equipment is widely used in oil and chemical companies, and the quality of such equipment has a direct impact on the output and quality of the products manufactured by these companies. Moreover, the production costs of chemical enterprises depend to a large extent on the sophistication of their chemical equipment. The most common problem with chemical processing equipment is corrosion that occurs over time as a result of its long-term use, and relevant technicians must design anti-corrosion measures based on the extent of corrosion in the equipment. However, due to various constraints, there are many problems in the anti-corrosion measures for chemical equipment, which have a serious impact on the production safety and quality of chemical products. The article analyzes the causes of corrosion in equipment and formulates targeted anti-corrosion measures to ensure the performance of chemical processing equipment. 1 Reasons for corrosion in chemical equipment: The reason for corrosion in chemical equipment is the generation of large amounts of harmful substances such as carbon dioxide, sulfur dioxide, hydrogen sulfide, and sulfides during the long-term production processes in chemical enterprises. Under specific temperature and humidity conditions, harmful substances undergo chemical reactions with the materials of chemical equipment, resulting in corrosion of such equipment. Corrosion in chemical processing equipment undermines the structural stability of such equipment, severely affecting its safety performance. Corrosion of chemical equipment mainly falls into three types: chemical corrosion, electrochemical corrosion, and physical corrosion. Firstly, chemical corrosion occurs when the special material on the surface of a device reacts chemically with substances in the air, resulting in the formation of new oxidized substances that adhere to the device’s surface and damage the structure of the material there. The main reason for this is the high-temperature environment during the production of chemical products, which accelerates the reactions of substances on the surface of the equipment. Secondly, electrochemical corrosion is a phenomenon of corrosion that occurs in chemical processing equipment when it comes into contact with dielectric solutions, as a result of electrode reactions. The main reason for this is that the environment in which chemical processing equipment operates is relatively humid. Finally, physical corrosion refers to the physical dissolution of the metal material in chemical processing equipment, which damages the performance of such equipment. During physical corrosion, no chemical or electrochemical reactions take place. 2 Control measures for chemical equipment corrosion 2.1 Enhancing the professional skills of anti-corrosion workers Corrosion of chemical equipment can significantly affect its safety performance; therefore, when carrying out anti-corrosion tasks, it is necessary to improve the technical expertise of those responsible for such work to ensure that anti-corrosion measures are implemented in a scientific and effective manner. The prerequisite for ensuring the scientific approach to corrosion prevention is that relevant staff receive training in professional knowledge and skills related to corrosion prevention, and that appropriate departments supervise and inspect the quality of each step in this process. This ensures that such staff fully understand the importance of chemical equipment in the production of chemical products, and that they adhere strictly to the relevant operating standards during equipment use, thereby preventing operational errors and equipment corrosion. Failure to do so can create safety risks in production processes and affect the quality of chemical products. 2.2 Corrosion prevention measures for the surfaces of chemical equipment: During corrosion prevention operations, the first step is to address the corrosion issues present on the surfaces of chemical equipment. Generally, when corrosion occurs on the surface of chemical processing equipment, sandblasting or the use of sprays is employed to cover the corroded areas. Before carrying out sandblasting, it is necessary to thoroughly remove rust and oxides from the surface of the equipment, and to ensure that the area to be treated is clean and dry. Then, the sandblasting mixture is prepared, and care must be taken to maintain the correct proportions during this process to ensure that the mixture meets relevant standards. Finally, the surface of the equipment is fully coated to prevent further corrosion. 2.3 Control of chemical medium concentration: Corrosion in chemical processing equipment is largely related to chemical media, and the concentration of these chemical media is the main cause of corrosion in such equipment. Under normal circumstances, certain concentrations of sodium hydroxide, hydrogen sulfide, water, and other chemicals in the medium directly cause corrosion of equipment. When welding steel components used in chemical processing equipment, it is essential to strictly control the ratio of hydrogen sulfide to water in order to maximize the time before stress corrosion cracking occurs in the welded joints. However, different welding methods and techniques are employed depending on the type of steel material. For example, if the material of the steel is carbon steel or low-alloy steel, it is necessary to strictly control the concentration of sodium hydroxide during welding, and the ambient temperature during welding should not be too high in order to prevent stress corrosion cracking after welding. 2.4 Proper use of anti-corrosion coatings There are many various methods for preventing corrosion in chemical equipment, among which anti-corrosion coatings are the most commonly used method; this approach is widely applied in the task of protecting chemical equipment in petrochemical enterprises. Proper use of anti-corrosion coatings can effectively prevent corrosion in chemical equipment. The main functions of anti-corrosion coatings can be manifested in the following aspects: First, anti-corrosion coatings can effectively isolate the surface of chemical equipment from relevant corrosive substances, providing strong protection for such equipment. Anticorrosive coatings are also insulating materials; when applied to the surface of equipment, they can effectively block the path of corrosion currents, preventing electrochemical reactions between the materials of chemical processing equipment and the relevant media through electrolytes. Secondly, anti-corrosion coatings can slow down the rate of corrosion by forming a reinforced protective layer. The mechanism by which ordinary coatings create such a protective layer is that the chemical substances contained in the coatings react with water vapor in the air, resulting in the formation of a reinforced protective layer that adheres to the surface of industrial equipment, thereby slowing down the corrosion of the metal components of that equipment to the greatest extent possible. Thirdly, anti-corrosion coatings provide some protection for the negative electrode in electrochemical reactions. Since the electrode potential of the protective film formed by the coating is higher than that of the metal materials in chemical equipment, in electrochemical corrosion the coating can act as the positive electrode, offering a certain degree of protection to the negative electrode. This is an important factor in preventing corrosion in chemical equipment. 2.5 Using corrosion inhibitors for protection A common method used in corrosion prevention in chemical plants is the application of corrosion inhibitors. The main principle behind their use is to slow down the rate of corrosion of the metal components in chemical equipment at low concentrations. Corrosion inhibitors also have many advantages; for example, they are relatively inexpensive and easy to use, which is why they are widely employed in the corrosion protection of chemical equipment. During use, the corrosion inhibitor utilizes relevant media to form an adsorption film on the surface of the electrode, thereby increasing the rate of electrode polarization in electrochemical corrosion and effectively reducing the corrosion rate of chemical processing equipment caused by corrosion currents. Of course, when using corrosion inhibitors, it is necessary to thoroughly analyze the properties and characteristics of the materials used in chemical equipment. Based on these analyses, an appropriate corrosion inhibitor should be selected for the anti-corrosion protection of such equipment, thereby ensuring effective protection against corrosion and maintaining the efficiency and safety of the chemical equipment. Conclusion In summary, corrosion of chemical processing equipment is directly related to the quality and safety of its use, and it has a crucial impact on both the volume and quality of the products manufactured by chemical companies. Therefore, relevant companies need to carefully analyze the reasons for corrosion in chemical equipment and take appropriate measures to slow down the rate of corrosion or prevent it from occurring, thereby ensuring the efficient and safe operation of the equipment.
