Abstract

A liquid separator assembly for separating a liquid from a liquid-entrained vapor is provided. The separator assembly includes a housing having an interior wall that is configured to define a containment chamber. A downstream pipe is provided that is coupled to the housing and is in fluid communication with the containment chamber to discharge vapor from the housing. An upstream pipe is provided that is coupled to the housing and is in fluid communication with the containment chamber to introduce the liquid-entrained vapor into the housing. The upstream pipe is formed to include an expansion mechanism in the containment chamber for expanding and cooling the liquid-entrained vapor discharged in the containment chamber to induce condensation of the liquid entrained in the vapor onto the interior wall of the housing. A liquid return conduit is provided for conducting condensed liquid collecting in the containment chamber to a point of use.

Claims9

Dependent claims

A liquid separator assembly comprising

a housing means having an interior wall configured to define a containment expansion chamber means, surrounded by an environment to be at a relatively cool temperature,
inlet means for admitting liquid-entrained vapor into the housing means from a relatively warmer vapor source than is said surrounding environment,
outlet means for discharging air from the housing means to a first point of use,
opening means located in the inlet means for directly passing the liquid entrained vapor from the inlet means into the containment expansion chamber means whereby said liquid entrained vapor is expanded through the opening means and condenses against said interior wall for separating liquid from the liquid-entrained air admitted into the housing means through the inlet means, and wherein said separated liquid collects in the housing means, and
passageway means situated within the inlet means for conducting said separated liquid collected in said housing means to a second point of use through a portion of the inlet means.
