Total pressure of propane and a little nitrogen
Thread Content
Hello everyone. The vapor pressure of propane at equilibrium is around 9 bar. I would like to ask: if there is a tank containing propane along with some nitrogen, how will the presence of that nitrogen affect the total pressure of the entire system?

For example, if propane makes up 90% of the gas phase and the total pressure is 10 bar, then if propane constitutes x% of the gas phase, the total pressure will be 9 bar/x%. At this point, nitrogen is entirely in the gas phase, so there is no issue with nitrogen saturation pressure; only the percentage of nitrogen in the gas phase and its partial pressure matter.
Equal to the vapor pressure of propane + the partial pressure of nitrogen
