The discussion revolves around the behavior of propane and butane in a half-empty LPG cylinder, specifically whether the ratio of these gases changes as the contents are used. Participants explore the implications of using vapor versus liquid and the effects of vapor pressure on the gas mixture.
Participants do not reach a consensus, as there are multiple competing views regarding the behavior of the gas mixture and the conditions under which the gases are used.
Participants highlight the importance of specific conditions, such as whether gas is being taken from the vapor phase or liquid phase, which may influence the outcome of the discussion.
The outtake of gas will be in gas-phase (Vapor)Bystander said:"Yes."
You will have to be more specific about conditions.
The outtake of gas will be in gas-phase (Vapor)Averagesupernova said:It depends on whether you are just using vapor off the top of the tank or taking liquid.
So, the gasses keep their own properties and will not be a combination of the two?Chestermiller said:The Propane has a higher vapor pressure than the Butane, so the propane will be used faster, and the liquid will become richer in butane.
The exit vapor will be an intimate mixture of butane and propane in proportions described approximately by Raolt's Law.Saint1968 said:So, the gasses keep their own properties and will not be a combination of the two?
