what is the name of the process used to separate the components of petroleum
Petroleum Petroleum (from Ancient Greek: petra: "rock" + oleum: "oil"[1][2][3][4][5][6]) is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column.
Honing oil In the context of hand blade sharpening, honing oil is used on a sharpening stone to protect the stone, carry away the debris (swarf), and to more efficiently produce a keen edge on a metal blade such as a knife.[1] In a machine shop it also carries away excess heat and depending on composition, may prevent unintentional tearing and welding of the metal. Or when used with materials such as soft copper, it may have extra additives to prevent stone loading, or metal deactivators to prevent staining of copper containing alloys.[2] To achieve maximum cutting rates and abrasive life with petroleum (mineral) based machining oils when honing difficult materials like stainless steel, a higher level of surface active lubricity agents are combined with sulfur extreme pressure additives.[3] Industrial honing oil is typically available in: 5 gal pails, 55 gal drums, 275 gal and 330 gal totes, while home knife honing oils are typically available in 1 oz, 4 oz, and 12 oz. bottles.[4]
