Shida Shenghua has obtained a patent for a new nitrogen sealing device for methyl ethyl carbonate storage tanks, which helps maintain stable pressure inside the tanks. According to information from the Intellectual Property Office, Dongying Shida Shenghua New Materials Co., Ltd. has been granted a patent titled “New Nitrogen Sealing Device for Methyl Ethyl Carbonate Storage Tanks”; the approval number is CN223242524U, and the application was submitted in November 2024. The patent abstract indicates that this utility model discloses a new type of nitrogen sealing device for methyl ethyl carbonate storage tanks. It includes a tank body; a feed pipe is fixed at the upper end of the tank body, a pressure gauge is also fixed at the upper end of the same tank body. An nitrogen inlet pipe is fixed on one side of the upper end of the tank body, while an nitrogen outlet pipe is fixed on the other side. A backup nitrogen regulation mechanism is provided on the outer wall of the tank body. This utility model is equipped with a backup nitrogen regulation mechanism; in the event that the first nitrogen control valve and the second control valve become damaged, the third and fourth pressure transmitters can be used to activate this backup mechanism, thereby maintaining stable air pressure inside the tank. This prevents air from entering the tank, which could affect the quality and safety of ethyl methyl carbonate. It also improves the airtightness of the tank, ensuring the safety of ethyl methyl carbonate during transportation and storage.
