In the modern chemical industry, equipment protection is like a solid line of defense, ensuring the safe and efficient operation of the production process. Chemical equipment usually needs to work in extreme environments, such as high temperature, high pressure, strong acid or strong alkali, and other conditions, which pose severe challenges to equipment materials. Therefore, it is particularly important to take effective protective measures. As a highly efficient preservative, dimorpholinyldiethyl ether (DMDEE) plays an irreplaceable role in the protection of chemical equipment.

The importance of equipment protection

The normal operation of chemical equipment is directly related to the efficiency and safety of the entire production process. Once the equipment is damaged due to corrosion or other reasons, it will not only cause the production line to be interrupted, but may also cause serious safety accidents. According to statistics, the global economic losses caused by corrosion are as high as trillions of dollars each year, among which the losses in the chemical industry are particularly prominent. Therefore, strengthening equipment protection is not only a cost reductionEffective means are key measures to ensure safe production.

Limitations of current protection technology

Although there are currently a variety of equipment protection technologies, such as coatings, cathode protection and corrosion inhibitors, each method has its limitations. For example, although traditional coating technology can isolate corrosive media to a certain extent, it is prone to failure due to mechanical damage or aging; cathode protection has high requirements for the material of the equipment and has high maintenance costs. In contrast, as a new corrosion inhibitor, DMDEE has gradually become the new favorite for chemical equipment protection with its unique molecular structure and excellent performance.

The application advantages of DMDEE

The reason why DMDEE can stand out among many protection technologies is mainly due to the following advantages:

Efficient corrosion protection: DMDEE can form a dense protective film on the metal surface, effectively preventing corrosive media from contacting metal and significantly reducing the corrosion rate.
Wide applicability: Whether it is carbon steel, stainless steel or copper alloy, DMDEE can provide good protection and is suitable for chemical equipment of various materials.
Easy to operate: DMDEE is usually added to the process system in liquid form, without the need for complex construction equipment or special treatments, greatly simplifying the operation process.
Environmentally friendly: Compared with traditional chromium-containing and phosphorus-containing corrosion inhibitors, DMDEE has lower toxicity and has less impact on the environment, which is in line with the development trend of green chemical industry.

Status of domestic and foreign research

In recent years, domestic and foreign scholars have made significant progress in the research on DMDEE. Some well-known foreign chemical companies have successfully applied DMDEE to petroleum refining, natural gas transportation and other fields, and have achieved good results. Relevant domestic research started late but developed rapidly, especially in the optimization of DMDEE synthesis process and exploration of practical applications, and has achieved a series of important results.

For example, a study showed that in experiments simulated acidic environments, the corrosion rate of carbon steel decreased by nearly 90% after adding DMDEE. Another study found that when DMDEE works synergistically with other additives, it can further improve its protective effect, providing new ideas for the development of a multifunctional composite protection system.

To sum up, chemical equipment protection is a complex and important task, and DMDEE, as an emerging protective material, is gradually changing the traditional pattern in this field with its unique advantages and broad application prospects. With the continuous advancement of technology, I believe DMDEE will play a more important role in the protection of chemical equipment in the future.
