The process is called fractional distillation. It works by heating up the crude oil inside a chamber to a boil (vaporizing it). Due to the fact that each component of crude oil has a different boiling point, each component of the crude oil will condense at a different height inside the chamber since the chamber gets colder the further up you go away from the heat source. Since each component condenses at different heights in the chamber, there are places to collect condensing liquid at different heights in the chamber (The heights correspond to the boiling point of each component). These collection areas will collect only the component of crude oil that condenses at that temperature. The condensing point is basically the boiling point which means the lower in the chamber that component condenses at, the higher the boiling point for that component is and therefore the heavier that component is (the heavier components get collected near the bottom of the chamber while the lighter components get collected near the top of the chamber).

I hope this helps. Let me know if anything is unclear.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
