Question

Propane turns into liquid after this has been done?

Answer 1

When the temperature is below the boiling point. At atmospheric pressure this is about -42°C. The boiling point will increase if the pressure is increased.  Is that what you were looking for?  ...Good Luck...

Additional: It would work basically like a home air conditioner. Freon 22 has a boiling point of about -40.8°C. The gas is compressed to raise the boiling point which also raises the temperature of the gas. It is then passed through a condenser to lower the temperature until it is below the boiling point..

Answer 2

After compression to around 20 atm, and cooling to ambient temperature, Gaseous Propane will condense to a liquid.

(This is a process used in the production of LPG (Liquefied Petroleum Gas).

Propane liquid stored at ambient temperature (70°F or 21°C), has a vapour pressure of around 300psi. (20atm).

Answer 3

After it has been cooled to a temperature lower than -42 degrees Farenheit

-OR-

It is stored in a pressure vessel with 200 lbs. or more working pressure.

Answer 4

Propane can be liquefied by pressure at room temperature. You must be familiar with the common LPG tanks that are used for many uses about the home. This gas can have up to 90% propane. I do not think that the pressure is very high. I have a small canister containing propane gas that I use to refill my gaslighter, and although this contains 100% propane, ir is made from light steel and has a plastic valve on the top. When I open my large gas tank, 48kg gas, the pressure is not high straight out of the tank. At a guess, not exceeding 5 atm

Answer 5

Applied a boatload of pressure or cooled it or, more likely, both.
