Abstract
An apparatus for dispersing the relative flows of a separated two phase flow using a nozzle positioned immediately downstream from a bend in a pipe. The inlet of the nozzle is adjacent an external wall of the pipe and the outlet of the nozzle is substantially on a longitudinal axis of the pipe. The dense phase is collected and transported through the nozzle back into the center of the pipe for uniform mixing and dispersion.
Claims2
An apparatus for dispersing the relative flows of a two phase flow through a pipe having a longitudinal axis, an upstream end and a downstream end, and means for providing a two phase flow to the upstream end of the pipe, comprising:
- means for substantially separating the two phase fluid flow into a dense phase and a light phase inside the pipe adjacent the upstream end;
- and
- nozzle means for collecting and transporting the dense phase separately through a first section of the pipe to a second section of the pipe downstream of the first section, said nozzle means being situated downstream of the separating means, said nozzle means having an arcuate shape with a substantially oval inlet adjacent an external wall of the pipe and an outlet substantially on a longitudinal axis of the pipe, the nozzle means being arcuate in shape, having a taper from the inlet to the outlet, and the inlet of the nozzle means having a larger opening than the outlet of the nozzle means.
