Abstract
A gas/liquid separator (1) assembly is provided. The assembly generally comprises a vessel with at least one internally received serviceable separator element (10) arrangement. A unique inlet baffle arrangement (36,39) is provided, to facilitate preseparation of liquid from gases, as gases are passed through the assembly. The assembly is particularly adapted for use in air/oil separation, for example for compressors. Methods of assembly and use are also described.
Claims14
A gas/liquid separator assembly comprising:
- (a) a pressure vessel including an outer wall and having a gas flow inlet, a gas flow outlet, and a lower sump;
- (b) a preseparation assembly positioned within the pressure vessel including:
- (i) a radially continuous, impermeable, axial shroud positioned spaced from the vessel outer wall to define a gas flow annulus therebetween;
- (ii) a cover extending between the vessel outer wall and the axial shroud at a location above the gas flow inlet and below the gas flow outlet;
- (iii) a base;
- and
- (iv) a porous shroud extending downwardly from the impermeable axial shroud and located below the base;
- and
- (c) a mounting space in the base configured to mount at least one removable and replaceable separator element.
