Abstract

An in situ retrofit assembly for a top entry valve includes an annular conduit (100) configured to conform with a seat support (106) at the distal end (207) and a valve body extension (208) with an interior annular region (301). The valve body extension (208) comprises an inlet port (209) fluidically connected to the annular area (301). A gland packing push plate (211) is configured to allow the annular conduit (100) to pass through thereby forming an outlet port (212). This allows the removal of a portion of the fluid from the cold box for downstream processing or manipulation as desired.
