Vapor pressure at boiling point
Thread Content
Dear experts, I would like to ask for your advice! Liquids with a boiling point below 45°C need to be placed in pressure vessels; at the boiling point, isn’t it true that the saturated vapor pressure of the liquid equals the atmospheric pressure? There is one question: is this pressure absolute or gauge pressure? If it is absolute pressure, then this pressure cannot reach the 0.1 MPa specified for pressure vessels
The gauge pressure is 0 at the boiling point. The boiling point applies only to open systems; the boiling point value for closed systems can serve only as a reference and has no practical significance. Investigating the relationship between vapor pressure and temperature in a closed system
The operating pressure of your container must be higher than the saturation vapor pressure to ensure that vaporization does not occur.
If I make it into an atmospheric pressure tank, isn’t that just an open system?
