Abstract
An apparatus for mounting a fluid cryogen injection nozzle to the exterior surface of a side wall of a cryogenic process vessel for permitting injection of a fluid cryogen into the interior of the cryogenic process vessel, the mounting apparatus including a base member and a rotatable insert member engaged with the base member, the rotatable insert member including a template for creating an opening in the side wall of the process vessel that is configured to accept the cryogen injection nozzle, and for attaching mechanical fasteners to the side wall of the process vessel in a defined pattern, such as a concentric pattern about the opening in the side wall of the cryogenic process vessel. A related mounting method is also provided.
Claims22
An apparatus for mounting a cryogen injection nozzle to a side wall of a cryogenic processing vessel, the apparatus comprising:
- a base member having opposite facing first and second base member sides, and a base member opening extending through the base member;
- and
- an insert member rotatably positioned within the opening of the base member, the insert member comprising first and second insert member sides, a first insert opening extending through the insert member, and a plurality of second insert openings positioned around the first insert opening and extending through the insert member.
A method for mounting a cryogen injection nozzle to a side wall of a cryogenic processing vessel comprising:
- (a) removably attaching an apparatus for mounting the cryogen injection nozzle to the side wall of the vessel, the apparatus comprising:
- a base member having opposite facing first and second base member sides and a base member opening extending through the base member, and an insert member rotatably positioned within the opening of the base member, the insert member comprising first and second insert member sides, a first insert opening extending through the insert member, and a plurality of second insert openings positioned around the first insert opening and extending through the insert member;
- (b) creating an opening in the side wall of the vessel by passing an opening-forming means through the first insert opening of the insert member of the apparatus and the side wall of the cryogenic processing vessel;
- (c) attaching mechanical fasteners to the exterior surface of the side wall of the cryogen processing vessel in a concentric pattern around the opening formed in the side wall by passing a mechanical fastener through each of the second insert openings of the insert member of the mounting apparatus;
- (d) removing the mounting apparatus from the side wall of the cryogenic processing vessel;
- and (e) attaching the cryogen injection nozzle to the exterior surface of the side wall of the cryogenic processing vessel.
