Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force. One type of gravity separator lifts the material by vacuum over an inclined vibrating screen covered deck. This results in the

Historical development of the gravity method in exploration

The gravity method was the first geophysical technique to be used in oil and gas exploration. Despite being eclipsed by seismology, it has continued to be an important and sometimes crucial constraint in a number of exploration areas. In oil exploration the gravity method is particularly applicable in salt provinces, overthrust and foothills belts,

Alternatives to conventional gravity separation methods

1999年12月1日  Conventional separation Conventional gravity separation uses the force of gravity to affect separation. Since oil and water have different densities, the force of gravity causes the more dense substance to fall to the bottom of the separation vessel while the lighter, less dense liquid rises.
