Questions regarding the true vapor pressure
Thread Content
May I ask: What are the true vapor pressures of the following media in KPa? Diesel hydrogenation feedstock, naphtha, reformed refined oil, methanol, light contaminated oil, MTBE, catalytic gasoline, atmospheric pressure diesel
By searching for the Antoine equation online, one can find coefficients for nearly a hundred substances; by plugging these values in, calculations can be performed. For substances for which no coefficients are available, however, there is no way to carry out calculations
I would like to ask what is the difference between the so-called true vapor pressure and the commonly referred to saturated vapor pressure?
Truth means “actual,” and saturation means being in a saturated state. This is a logical issue, not a technical one; ask a logic teacher
The term vapor pressure is also often seen in pollution emission standards
Antoine’s formula is used to calculate the saturated vapor pressure of substances at different temperatures. Do you understand? ? Isn’t this still the saturated vapor pressure?
For calculating the saturated vapor pressure using Antoine’s equation, you can use the hint you provided. Real gases are not necessarily in a saturated state; they may be in an unsaturated state, in which case their partial pressure is less than their corresponding saturated vapor pressure
It’s not in a saturated state – can the Antoine equation be used?
Teach me? Do you know under what conditions something is saturated and under what conditions it is not?
