A casing intended to be equipped with at least one section of packing for a gas/liquid separation column includes at least a tubular wall extending along a longitudinal direction between two longitudinal ends and an internal face of which contributes to delimiting a housing for the section of packing, the tubular wall contributing to delimiting, at one of its longitudinal ends, an entry opening, the casing including an end wall located at the opposite longitudinal end to the entry opening, the casing including at least a first hooping device and at least a second hooping device which are positioned around the tubular wall of the casing in contact with an external face of the tubular wall, the first hooping device including at least one zone of connection with a movement system for the moving of the casing, the second hooping device having a longitudinal dimension shorter than a longitudinal dimension of the first hooping device.

This disclosure describes an improved heat transfer system for use in reaction vessels used in chemical and biological processes. In one embodiment, a heat transfer baffle comprising two sub-assemblies adjoined to one another is provided.

A dynamic catalytic conversion reactor having a plurality of operating zones is disclosed that adjusts operation based on incoming hydrogen from a fluctuating renewable energy source. The dynamic reactor is configured to turn on and off supply of feed gas to certain zones based on hydrogen supply, and maintains catalyst activity within all operating and idle zones by applying one of a number of gas flow options through the idle zones. Methods and systems of using the dynamic reactor are also disclosed.

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.
