[QUOTE="mugen08, post: 5637987, member: 604981"] Right on guys. Example= Crude oil refineries heat crude oil to 650 degrees or so and introduce the oil to a large tower at atmospheric pressure. At this temperature, most of the oil evarorates, rises into the tower, and later condenses into kerosene, deisel, gasoline, butane, and propane (each condensing back at a lower and lower temperature). The product that doesn't evaporate (basically a sludge, like liquid asphault), leaves the bottom of the tower and goes to a "vacuum) unit. In this unit, it is heated to about 750 degrees, and introduced to a vacuum that causes the heavy liquid to boil, and extract any remaining gases. On the other end of the process, the butanes and propanes that rise out of the first tower are compressed and turned back into a liquid for storage and transport. So.....Lower pressure=lower boiling temperature .........Higher pressure= higher boiling temperature. This is why you can compress water to 800 psi or so and heat the shit out of it until it boils, creating a superheated steam that is invisible but can cut you in half at that pressure and temperature.
