Abstract

The following disclosure related to gas-liquid separation in a two-phase flow. More specifically, the following disclosure relates to passive gas-liquid separation of a two-phase flow in an outlet manifold that combines an outlet flow from a plurality of electrolytic cells or an electrolytic cell stack where performance may be dependent on shape of a conduit conveying the two-phase flow.

Claims (14)

1 . A gas-liquid separator apparatus comprising:

an inlet configured to receive a first portion of a two-phase flow, the first portion flowing through a center of a conduit;

a converging channel fluidly coupled to the inlet and configured to receive the first portion of the two-phase flow;

a first outlet fluidly coupled to the inlet and the converging channel and configured to receive the first portion of the two-phase flow;

a collector plate configured to receive a second portion of the two-phase flow, the second portion flowing at an outside of the conduit and not flowing through the inlet; and

a second outlet fluidly coupled to the collector plate and configured to receive the second portion of the two-phase flow.

2 . The gas-liquid separator apparatus of claim 1 , further comprising:

a center channel fluidly connected to the inlet, the converging channel, and the first outlet, the center channel located between and connecting the converging channel and the first outlet.

3 . The gas-liquid separator apparatus of claim 2 , further comprising:

fins located on the converging channel or the center channel.

4 . The gas-liquid separator apparatus of claim 3 , wherein the conduit is an outlet manifold connected to a plurality of electrolytic cells or an electrolytic cell stack.

5 . The gas-liquid separator apparatus of claim 3 , wherein the conduit is a circular conduit.

6 . The gas-liquid separator apparatus of claim 1 , wherein the conduit is an outlet manifold connected to a plurality of electrolytic cells or an electrolytic cell stack.

7 . The gas-liquid separator apparatus of claim 1 , wherein the conduit is a circular conduit.
