Can you boil water out of oil?

Why does water boil over when adding salt?

In order for water to boil, its vapor pressure has to equal the pressure of the atmosphere, Giddings said. … When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said.

How do you flush water out of oil?

There are two common ways to remove water from lube oil- one is by coalescing the water. Coalescence is the method of joining water droplets together to form an increasingly sized pool of water which can then be removed from the oil in order for it to be purified and re-used successfully.
