Wet gases are usually processed with either two (one separator and stock-tank) or three (two separators and stock-tank) stage separation system. If two-stage separation is utilized, we can use Eq. 4.6 to estimate the reservoir gas specific gravity. The equation requires knowledge of both the separator GOR and the stock-tank GOR (which is ...
Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)

Wet separation is particularly effective at removing glass fragments and other sharp objects, which tend to be heavier than organic materials. Ballistic separation takes advantage of both density and elasticity differences to separate inert and organic constituents. This method can be used in either initial processing or in the refinement of ...

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. A vertical vessel allows …

Figure 1 conceptually displays gravity separation. The fundamental engineering principle of gravity separation is the settling velocities of particles, and recognition of two types of settling in stormwater treatment: dynamic and quiescent. Settling velocity is affected by particle size, shape, and specific gravity and by water temperature.
