Effectively eliminate hidden dangers in the use of cryogenic storage tanks

Cryogenic storage tanks belong to three types of pressure vessels. The safety management of cryogenic storage tanks involves many aspects. Only the overall and systematic safety management of cryogenic storage tanks can be effectively prevented in order to effectively control all related processes, equipment, instruments, and other links so that they are in a controlled state. occur.
 
Today we will talk about how to effectively eliminate the safety hazards of cryogenic storage tanks:
1. The cryogenic storage tank should be provided with anti-sun measures and a fixed cooling water spray system.
 
2. The safety valve outlet pipe of the cryogenic storage tank should be connected to the production recovery system or the water tank for absorption.
 
3. The liquid phase inlet and outlet pipelines of the cryogenic liquid storage tank shall be provided with an emergency shut-off valve; the operating position of the emergency shut-off valve shall not be less than 15 meters from the cryogenic storage tank, and shall be able to start within 5 meters of the filling operation point or in the control room .
 
4. Full-pressure cryogenic storage tanks shall be provided with fire protection dykes and meet the requirements for setting up "clean water" storage facilities.

 

5. The measurement of important parameters such as the pressure, temperature, liquid level, leakage alarm of the cryogenic liquid storage tank shall be remotely transmitted and continuously recorded, and the necessary video monitoring system shall be set up.
 
6. Process alarm, interlock, emergency pressure relief, flammable and toxic gas alarm device should be regularly checked, calibrated and maintained to ensure that it is complete, effective, sensitive and easy to use.
 
7. Strengthen the "no leakage" management of cryogenic storage tanks. Root valves, inlet and outlet valves, flanges, gaskets, and instrument pipelines connected to storage tanks should be registered and filed. Regular inspections should be performed to find hidden dangers. Tank or parking.
 
8. Adequate fire protection and air defense facilities and equipment should be provided in accordance with relevant regulations to establish a stable and reliable fire protection system.
