There are two main types of gravity separators in upstream service: two-phase (gas/liquid) and three-phase (gas/liquid/liquid). The gas/liquid separators are often vertical as the separation is frequently limited by liquid removal from gas and controlled by gas velocity/momentum.
Principles and Methods of Gravity Separation. Gravity separation processes can be broadly categorized into four main types:-Heavy medium separation (H.M.S. Baths, cyclones, etc.) Stratification in a pulsed or moving dense bed (Jigs). Film sizing with a thin flowing liquid film (Vanners, frames, etc.) Centrifugal separation …
Spherical separators are a type of vertical separator. It is affordable and has a compact vessel arrangement. These types of separators have relatively little surge room and a liquid settling section. They are ineffective when a well stream contains excessive mud or sand or is subjected to surging y components.
Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces).
The Jig separator concentrator is an effective gravity separation machine based on the ore material density difference.
Mineral jigs are a type of mining equipment, also referred to as gravity concentrators or jig concentrators, that are used in operations to separate different ore materials based on their densities.
