Document Type and Number:
WIPO Patent Application WO/2017/079898
Kind Code:
A1
Abstract:
A press-fit in situ retrofit assembly for a top entry valve and a method thereof are disclosed. The assembly includes an annular conduit (201) including a segment (202) of reduced outside diameter and a shoulder (203) on the exterior surface at the proximal end (204), and is configured to conform with an interior surface (205) of a valve seat (206) at the distal end (207). A valve body extension (208) with an interior annular region (301), and an inlet port (209) fluidically connected to the annular region (301). A gland packing push plate (211) is configured to allow the annular conduit (201) to pass through thereby forming an outlet port (212). And a thrust plate (403) is attached to the thrust screws (401). The thrust plate (403) allows the segment (202) of reduced outside diameter at the proximal end (204) of the annular conduit (201) to pass through, with the thrust plate (403) seating on the shoulder (203). The assembly and the method allow the removal of a portion of the fluid from the cold box for downstream processing or manipulation as desired.
