Abstract:
A fuel gas scrubber for removing liquids, the fuel gas scrubber comprising:a pressure vessel having a base, an exterior sidewall and a top;a dry gas outlet aperture extending through the top of the vessel for facilitating exhaust of gases from the vessel, a wet gas inlet extending through the exterior sidewall of the vessel, a liquid outlet extending through the exterior sidewall of the vessel, and the wet gas inlet being located between the top and the base;a tubular housing having a first end, an opposed second end, an exterior sidewall, and an interior bore extending from the first end to the second end;the first end of the tubular housing being secured to the dry gas outlet aperture in the top of the vessel to facilitate communication therewith, and the tubular housing being suspended within the vessel and extending toward the base such that the second end of the tubular housing is locate closer to the base than the wet gas inlet;a valve seat being positioned within the interior bore adjacent the first end of the tubular housing;a float being encapsulated within the interior bore of the tubular housing and being protected, via the exterior sidewall of the tubular housing, from an entry force of any wet gases entering the vessel through the wet gas inlet, the float being axially movable between the first end and the second end of the tubular housing, and the float having a valve seat end facing the first end of the tubular housing and a fluid engaging end facing the second end of the tubular housing;a valve member being positioned on the valve seat end of the float; andan inlet at the second end of the tubular housing, such that any fluid entering the tubular housing causes the float to move axially along the interior bore until the valve member carried by the float engages the valve seat to seal the first end of the tubular housing.
