Abstract
An improved centrifugal separator for vapor-liquid mixtures having a vertical upflow conduit closed at the top end and open at the bottom end. A plurality of curved arms similar in shape to a truncated torus of rectangular cross-section penetrate and extend within the conduit at its upper portion. A second plurality of curved arms are located immediately below the upper group and are contiguous thereto. The vertical upflow conduit has a lesser internal diameter in the lower portion, interconnected with a greater internal diameter portion in the upper portion by a frusto-conical section.
Claims2
A liquid-vapor separator device comprising:
- a vertically disposed cylindrical drum concentric with and in spaced surrounding relationship with a riser, forming an annulus therewith, and having means for discharge of a separated liquid at its lower end and means for discharge of a separated vapor at its upper end, the riser serving as a conduit for a two-phase flow of a fluid, open at its lower end to admit a liquid-vapor mixture and closed at its upper end, the riser being formed of upper and lower sections interconnected by a frusto-conical section, the upper section having an internal diameter greater than that of the lower section, a first plurality of curved arms radially disposed at the upper section of the riser, one end of each arm extending within the riser and in flow communication therewith, the opposite end of each arm extending into the annulus for discharge of the fluid and a second plurality of curved arms below the first plurality of arms and contiguous thereto.
