APPARATUS FOR SEPARATING LIQUID FROM A PROCESS GAS STREAM OF AN ELECTROCHEMICAL CELL STACK

摘要

A liquid separator configured to separate liquid from a fluid stream. The separator includes a housing, a separation chamber disposed within the housing, a drain, an inlet channel, a swirler disposed within the inlet channel, and an outlet channel. The drain has a drain passageway for draining liquid from the separation chamber. As well, the inlet channel is configured to communicate the fluid stream from a first inlet end to a second inlet end disposed within the housing and proximate the separation chamber. The outlet channel is configured to communicate the fluid stream from a first outlet end positioned proximate the second inlet end, to a second outlet end remote from the separation chamber. Preferably, the drain passageway comprises an inner diameter which is sized such that the interaction between the surface tension of the liquid and the inner passageway causes some liquid to be retained in the drain passageway, the retained liquid forming a low pressure gas seal of the drain passageway. The drain passageway is preferably substantially horizontal. The housing preferably includes a base and a cap which is removably mountable to the base.
