<p>A process and apparatus for safely delivering a hazardous fluid substance to a receiving structure includes a supply cylinder (12) containing the fluid substance and having a supply cylinder release port (16); a high pressure containment vessel (20) having a vessel wall (26) for receiving and safely enclosing the supply cylinder (12); a high pressure first tube (22) extending from, and in fluid communication with, the supply cylinder release port (16) to a vessel port (24) in the vessel wall (26); and a vessel valve in fluid communication with the first tube (22) for controlling delivery of the fluid substance from the supply cylinder (12) and from the vessel (20). The vessel valve preferably includes a fluid substance sensing valve assembly (30) mounted in the vessel port (24), for automatically shutting off the flow of the fluid substance at the vessel port (24) upon detection of the fluid substances outside the containment vessel (20). The vessel valve preferably includes a reduced orifice controller (36).</p> |
