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.

Abstract: An injection nozzle for injecting a substance, such as a cryogenic gas or cryogenic liquid, into the interior of a process vessel, or directly into material inside a process vessel, and includes a housing having a first internal chamber for receiving a fluid, and a second internal chamber having an actuator located therein, a valve body having an outlet, a stem positioned within the first internal chamber of the housing and having opposed proximal and distal ends, wherein the stem is reciprocally movable along its longitudinal axis in the housing to open and close the valve body outlet, and a sensor configured to receive a signal from the actuator.
