yes freezing point of commpresed natural gas is -296.7 and freezing point of water is 32 F and freezing point.

Freezing can occur not only when water in the gas stream mixes with temperatures below 32 degrees Fahrenheit, but also with the presence of hydrates well above the freezing mark.

Temperature of gas will drop nearly 50 degree Fahrenheit and will start freezing after this point. Freezing point of natural gas is minus 296.7 degree Fahrenheit

Saeed Abbasi
by Saeed Abbasi , Senior Resident Engineer , Osmani and Company Engineering Consultants

YES. Freezing point of water is 32 degree F. Gas temperature is reduced whenever pressure is reduced. Temperature of gas will drop nearly 50 degree Fahrenheit and will start freezing after this point. Freezing point of natural gas is minus 296.7 degree Fahrenheit
