<p>A cold trap includes a set of baffles (20) cooled by the cold finger of a closed cycle refrigerator (24). The baffles (20) are vertically disposed in a vertical fluid conduit (12) with frustoconical and conical surfaces for directing liquid to a circular trough during regeneration. After the liquid is collected, it is blown from the trough (34) through a pressure relief valve (40) by a nitrogen purge. The trough (34) is formed in the upper surface of a connecting flange (16) at the lower end of the fluid conduit.</p> |
