An apparatus for extending turndown in a gas-liquid separator is presented. The apparatus includes a first mist extractor with a first operating range and a second mist extractor with a second operating range. The mist extractors can be generally of the same type, with the second operating range being different than the first operating range. A gas stream containing entrained liquid droplets flows through the first mist extractor and then through the second mist extractor. Each mist extractor coalesces and captures the liquid droplets within its own operating range, expanding the overall operating range of the separator. Additional mist extractors may be added to cover any gap between the first and second operating ranges.

An inlet momentum absorber for passing an oil/water/gas mixture into a separator vessel having an inlet nozzle that extends through the vessel wall into the interior thereof, and a nozzle axis. A dish-shaped deflector is supported within the vessel adjacent to the deflector being intersected by the nozzle axis. A plurality of closely spaced apart cylindrical posts are arranged in an enlarged circumferential pattern defining a dispersing area within the vessel, the dispersing area being formed equilaterally around the nozzle axis. The closely spaced cylindrical posts provide a multitude of tortuous paths through which the oil/water/gas mixture flows from the dispersing area into the interior of the vessel. The tortuous paths are free of sharp edges to thereby minimize shearing of dispersed droplets.

Inlet device for large oil field separator

A demisting system used to remove entrained liquid droplets from a gas stream employing radially arranged serpentine vanes. The radial arrangement of the vanes provides flow paths in which the leading edges of the serpentine vanes are closer together than the trailing edges so that a gas stream must undergo a series of direction and velocity changes. Centrifugal forces act to cause liquid droplets to impinge on the surface of the vanes. Surface tension holds the liquid on the vanes as it collects and gravity causes the collected liquid to drain downward and out of the demisting system.
