What is the safe distance between liquid oxygen storage tanks
Date: Jun 09, 2020
The safety distance of the liquid oxygen storage tank should not be lower than the radius of the large tank adjacent to the two tanks. Liquid oxygen is a cryogenic liquid at -183°C. Storage should require heat insulation measures, otherwise it will vaporize into carbon dioxide, so the liquid oxygen storage tank It must be a vessel with a two-layer thermal insulation structure or a cryogenic liquid storage tank, such as an oxygen tank for gas cutting, an oxygen tank for hospital outpatients, and a liquid oxygen storage tank.
The cryogenic storage tank of this product is a two-layer fixed vacuum powder heat insulation storage tank. The material of the inner tank is stainless steel plate and the material of the outer tank is Q235B. The coating on the surface is shot blasting, paint spraying, purge, etc. At the same time, it also uses a rapid and stubborn liquid architectural coating.
1. The liquid oxygen storage tank is generally placed at a safety address next to the air separation plant to prevent open flames, pyrogens and flammable substances. The storage tank is prohibited from overpressure.
2. Liquid oxygen has magnetic rationality, and under the effect of charge and discharge, it is easy to produce active oxygen with very high specificity of organic chemistry. Therefore, fire or spark discharge is forbidden within 30m around the liquid oxygen storage tank, and explosion-proof equipment must be used.
3. The liquid oxygen in the liquid oxygen tank continues to volatilize, and the acetylene concentration value will increase, causing accumulation and dissolution, so as to be explosion-proof. The liquid oxygen in the liquid oxygen storage tank should be used as much as possible, often upgraded to avoid Acetylene accumulates and analyzes the water content of acetylene in liquid oxygen once a week. Exceeding the specifications, the liquid oxygen should be exhausted.
4. Air pressure gauges, vacuum gauges, liquid level gauges, alarm devices, valves, etc. of liquid oxygen storage tanks should be checked on time to ensure accuracy, dexterity, and safety.
5. When there is working pressure in the liquid oxygen storage tank, it is strictly forbidden to overhaul or tighten, and the pressure must be relieved first. In actual operation, the worker must formulate safety precautions and operating procedures.
