Abstract
Abstract The standard cap of an impingement cap entrainment separator is modified by the installation of fixed spiral vanes in the cap annulus or in the underside of the cap. The spiral vanes cause all of the liquid in the gas stream to be de-entrained and flow downward as a film on the cap skirt. The cap skirt also has a weir to collect the liquid and prevent re-entrainment.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
174 words
An entrainment separator comprising in combination a vessel fitted at the bottom with an upwardly directed riser pipe for discharging entraining gas within said vessel, impingement cap means comprising an impervious cap top disposed above the discharge end of said riser and a cylindrical cap skirt surrounding the upper portion of said riser, thereby creating an annulus between the riser and the cap skirt, said cap means acting to redirect the gas flowing through said riser pipe in a direction sharply away from the direction the gas had taken while passing through said riser pipe, extending intermediate the riser pipe and cylindrical cap skirt, a fixed spiral vane for imparting a swirling motion to the gas flowing through said annulus, thereby removing the entrained liquid from the gas by centrifugal force, weir collector means located at the bottom of said cap skirt and below said spiral vane for collecting the de-entrained liquid, drain means for removing the liquid from the weir and discharging the de-entrained liquid from the vessel and a clean gas outlet.
Claim 2
Dependent Claim
174 words

Claim 3
Dependent Claim
51 words
The apparatus of claim 1 wherein a fibrous bed structure is disposed transverse the open discharge end of said riser pipe, and said riser pipe is provided with a scrubbing liquid spray nozzle for discharging liquid substantially evenly across the cross section of said riser pipe upstream from said fibrous structure.
