Controlling contamination in hydrogen production from water-reactive aluminum
A system for controlling contamination in hydrogen production from water-reactive aluminum includes at least one reaction vessel. For example, each reaction vessel may include a container, a conduit, and a plurality of baffles. The container may define a volume, and the conduit may define an orifice outside of the container and spaced away from the container. The plurality of baffles may be disposed in the volume to form a tortuous flow path through the volume to the orifice of the conduit to facilitate rapid production of a large quantity of hydrogen from water-reactive aluminum while reducing the likelihood that ejecta, aerosols, or a combination thereof, may escape the reaction vessel to interfere with end-use of the hydrogen produced.
1. A rig for preparing an inflatable structure, the rig comprising:
a manifold including a junction and a plurality of runners, the plurality of runners in fluid communication with one another and releasably securable in fluid communication with a plurality of reaction vessels;
a connector in fluid communication with the plurality of runners via the junction, the connector defining a connection axis, and the connector releasably securable in fluid communication with the inflatable structure along the connection axis; and
a truss coupled to the manifold, the truss disposed about the connector to restrict movement of the inflatable structure laterally relative to the connection axis while the inflatable structure is releasably secured in fluid communication with the connector.
2. The rig of claim 1 , wherein the plurality of runners of the manifold are spaced relative to one another such that the plurality of runners are releasably securable in fluid communication with standard-sized 55-gallon drums adjacent to one another.
3. The rig of claim 1 , wherein the plurality of runners is releasably securable to the plurality of reaction vessels with the plurality of runners supporting the manifold away from the plurality of reaction vessels in an orientation with the connector facing away from the plurality of reaction vessels.
4. The rig of claim 1 , wherein the connector includes an O-ring positionable about a rigid inlet of an inflatable structure through an interference fit.
5. The rig of claim 1 , wherein the truss includes one or more canisters, each of the one or more canisters is coupled to a respective one of the plurality of runners, and each of the one or more canisters is operable to direct water-reactive material to the respective one of the plurality of runners.
6. The rig of claim 5 , wherein each one of the one or more canisters is operable to direct water-reactive material to the respective one of the plurality of runners under the force of gravity.
7. The rig of claim 5 , wherein each of the one or more canisters defines a respective compartment, and each compartment is sealable in fluidic isolation from the plurality of runners.
8. The rig of claim 5 , wherein the truss includes a plurality of supports, and each of the one or more canisters is coupled to a respective one of the plurality of supports.
9. The rig of claim 8 , wherein the plurality of supports are independently flexible relative to one another in a direction away from the connection axis.
10. The rig of claim 8 , wherein the plurality of supports correspond in number to the plurality of reaction vessels releasably securable in fluid communication with the plurality of runners of the manifold.
11. The rig of claim 1 , wherein the connector is self-releasable from the inflatable structure based on a state of inflation of the inflatable structure.
12. The rig of claim 1 , wherein the plurality of runners combine a plurality of flows away from the junction into a single flow at the junction.
13. The rig of claim 1 , wherein the plurality of runners are rigidly coupled to one another.
