On the safety issues of gasification units
Thread Content
Dear colleagues, I urge everyone to use their wisdom to discuss how to ensure the safe operation of coal chemical plants during production. What are the main safety hazards associated with such plants? As a coal chemical plant, what are the safety hazards that are specific to it? Gasification in coal chemical plants basically involves the use of pure oxygen. Regarding the safety aspects related to pure oxygen, which issues require special attention?
It possesses all the characteristics of chemical processing units (flammability and explosiveness, toxicity and harmfulness, high temperature and pressure, deep cold and negative pressure), which are also its safety hazards. Gasification in coal chemical plants basically involves the use of pure oxygen for gasification, right? Basically? Or part? I’m afraid my knowledge is limited.
I would like to mention a very important point here: pure oxygen storage tanks need to be dried out before use, and water should be drained from them regularly at intervals to prevent water from remaining inside the tank. Because under aerobic conditions, the tank walls are prone to corrosion, which thins them and reduces their pressure resistance.
Bro: Where does the oxygen you mentioned come from? If it were separated by air, how could there be water? The products produced at such low temperatures in air separation should not contain any water, right?
Your topic is quite large. Coal chemical industry also includes various types, such as gas production, synthetic ammonia production, methanol and dimethyl ether production, etc. The characteristics of each system vary; in general, they involve issues such as flammability and explosiveness, toxicity and harmfulness, as well as high temperatures and pressures. Regarding the issue you mentioned about the liquefaction of oxygen, it is in accordance with the relevant requirements of the \"Safety Technical Regulations for Oxygen and Related Gases\". You can also refer to the \"Safety Technical Regulations for Small Nitrogen Fertilizers\", which contain safety requirements regarding the use of oxygen.
Good point, but your question is too broad! You can’t even explain it with a whole book! There are corresponding safety technical specifications for various production units, processes, job types, and various activities within the production area.
The problem is significant; it’s just that during the gasification process to produce gas, there is gas involved (which is flammable, explosive, and toxic), so it is essential to prevent any leaks of gas during this process. Additionally, gas stoves and gas systems are prone to explosions, which is another issue that requires attention.
