Pressurize the steel cylinder containing flammable liquids with compressed air to 0.8 Mpa? Is there any danger?
Thread Content
I need help with what’s mentioned in the title: filling liquefied gas cylinders with flammable liquids such as methanol and ethanol, and then pressurizing them to 0.8 Mpa using compressed air. Is this process dangerous? Can air be used? Still use nitrogen? Could someone with experience give me some advice?
1. Oxygen is added. 2. Pressurization leads to an increase in temperature. With both temperature and oxygen present, this process must be dangerous. Why use air for pressurization? You can use warm water or slightly hot water from the outside to raise the temperature; in that case, pressure can also increase
