Precautions for air separation production

Thread Content

Precautions for air separation production: 1. Oxygen produced through air separation is a flammable substance; the use of fire and smoke is strictly prohibited. 2. Nitrogen produced by air separation is a asphyxiating gas; measures must be taken to prevent asphyxiation injuries. 3. The liquid produced by air separation is at around -170 to -190 degrees Celsius, so strict precautions must be taken to avoid frostbite. 4. The air separation pre-cooling system uses Freon, and leaks can cause environmental pollution. 5. In air separation pre-cooling systems that use ammonia coolers, ammonia leaks can lead to poisoning. 6. The liquids in the upper and lower towers contain harmful substances such as acetylene and hydrocarbons, which can cause explosions if they accumulate. 7. Many containers used in air separation are pressure vessels, and it is necessary to strictly control the pressure to prevent explosions of these vessels from causing injury to people. 8. When loading and unloading pearlescent sand, proper personal protection must be used to prevent people from falling from heights or from being suffocated or buried. 9. Prevent the occurrence of \"pulsation\" during the operation of the turbine compressor to avoid damaging the equipment. 10. For equipment maintenance, hot work, work at heights, and other similar tasks, the approval system must be strictly followed. 11. Pay attention to degreasing newly installed or repaired equipment. 12. Operate the valves slowly; never open or close them quickly. 13. Use copper tools; never use iron tools. 14. The liquid oxygen storage tank should have its total carbon and acetylene contents analyzed regularly.
