US 2026/0249263 A1 · VESSEL WITH JACKETED HEAD

Abstract

A pressure vessel with an external jacket for temperature control of contents within the vessel is provided. The vessel has a shell and two opposing heads. The external jacket is installed on at least one of the heads, and heating or cooling fluid is circulated through the jacket for temperature control. The jacket is formed by a plurality of concentrically arranged conduit rings that are welded to the exterior surface of the head of the vessel. Adjacent conduit rings are connected by jumper lines to allow the heating or cooling fluid to flow between conduit rings. Each conduit ring has flared side portions that allow the side portions of adjacent conduit rings to be welded to the vessel in a single weld pass. A circular groove may be machined into the head of the vessel, and the outermost conduit ring may be welded to the head at the circular groove.

Dependent claims

A vessel comprising:

a shell;
a head attached to an end of the shell;
and
a jacket comprising a plurality of conduit rings that are concentrically arranged, wherein each conduit ring of the plurality of conduit rings is integrally attached to an exterior surface of the head, wherein the exterior surface of the head and an interior side of each respective conduit ring of the plurality of conduit rings define a fluid passageway within each respective conduit ring of the plurality of conduit rings,
wherein the jacket further comprises at least one jumper line having a first end and a second end, wherein the first end of the at least one jumper line is connected to one respective conduit ring of the plurality of conduit rings, and wherein the second end of the at least one jumper line is connected to an adjacent conduit ring of the plurality of conduit rings such that adjacent conduit rings of the plurality of conduit rings are in fluid communication through the at least one jumper line.)

A vessel having an exterior surface, wherein the vessel comprises a jacket, the jacket comprising a plurality of conduit rings that are concentrically arranged, wherein each conduit ring of the plurality of conduit rings is integrally attached to the exterior surface of the vessel, wherein the exterior surface of the vessel and an interior side of each respective conduit ring of the plurality of conduit rings define a fluid passageway within each respective conduit ring of the plurality of conduit rings, and

wherein the jacket further comprises at least one jumper line having a first end and a second end, wherein the first end of the at least one jumper line is connected to one respective conduit ring of the plurality of conduit rings, and wherein the second end of the at least one jumper line is connected to an adjacent conduit ring of the plurality of conduit rings such that adjacent conduit rings of the plurality of conduit rings are in fluid communication through the at least one jumper line.)

A method of manufacturing a vessel, said method comprising the steps of:

providing a vessel constructed of weldable material and having an exterior surface;
forming a plurality of conduit rings configured to be concentrically arranged on the exterior surface of the vessel, wherein each conduit ring of the plurality of conduit rings is constructed of weldable material and defines a channel that is open along on an interior side of each conduit ring, wherein each conduit ring of the plurality of conduit rings has a center portion and two opposing side portions each integrally formed with the center portion, wherein the center portion has a concave inner surface, wherein the opposing side portions include an inner side portion extending around an inner circular perimeter of each conduit ring and an outer side portion extending around an outer circular perimeter of each conduit ring, wherein the inner side portion and the outer side portion of each conduit ring are flared outwardly from the center portion;
welding the inner side portion of each conduit ring of the plurality of conduit rings to the exterior surface of the vessel to form an inner welding joint at which the inner side portion of each conduit ring of the plurality of conduit rings is integrally attached to the vessel;
welding the outer side portion of each conduit ring of the plurality of conduit rings to the exterior surface of the vessel to form an outer welding joint at which the outer side portion of each conduit ring of the plurality of conduit rings is integrally attached to the vessel, wherein the exterior surface of the vessel and the interior side of each respective conduit ring of the plurality of conduit rings define a fluid passageway within each respective conduit ring of the plurality of conduit rings;
welding one end of a jumper line to the center portion of each respective conduit ring of the plurality of conduit rings, and welding an opposing end of the jumper line to the center portion of an adjacent conduit ring of the plurality of conduit rings such that adjacent conduit rings of the plurality of conduit rings are in fluid communication through the jumper line.)
