Abstract:
A multi-directional flow gravity separator for separating a mixture of two immiscible fluids having different densities including a heavier fluid and a lighter fluid, comprising:a vertical elongated tank with a first cross-sectional area, an upper portion, a lower portion, and an open top end, an elongated shroud in fluid communication with the tank, wherein the shroud has a second cross-sectional inner area which is less than the first cross-sectional inner area of the tank, and an open top end and a closed bottom end, wherein the open top end is in fluid communication with the tank, an inlet pipe for introducing the mixture into the shroud, wherein the pipe has a third cross-sectional inner area which is less than the second cross-sectional inner area of the shroud and an open first end outside the tank and a second end in fluid communication with the closed bottom end of the shroud, means for discharging the heavier fluid from the lower portion of the tank, and means for discharging the lighter fluid from the upper portion of the tank wherein the shroud further comprises a helical coalescer within the shroud.
