Assemblies, apparatuses, systems, and method to extract or convey a material from a source of the material may include a vacuum generation and sound attenuation assembly to enhance conveyance the material from the source of the material. The vacuum generation and sound attenuation assembly may include a vacuum source including a plurality of vacuum generators. Each of the plurality of vacuum generators may be positioned to cause a vacuum flow between the source of the material and the vacuum generation and sound attenuation assembly. The vacuum generation and sound attenuation assembly may further include a sound attenuation chamber connected to the vacuum source. The sound attenuation chamber may include an attenuation housing at least partially defining a chamber interior volume being positioned to receive at least a portion of the vacuum flow from the vacuum source and attenuate sound generated by the vacuum source.

A method for facilitating the distribution of the flow of one or more streams within a bed vessel is provided. Disposed within the bed vessel are internal materials and structures including multiple operating zones. One type of operating zone can be a processing zone composed of one or more beds of solid processing material. Another type of operating zone can be a treating zone. Treating zones can facilitate the distribution of the one or more streams fed to processing zones. The distribution can facilitate contact between the feed streams and the processing materials contained in the processing zones.

Mass transfer packing with a minimal surface or a triply periodic minimal surface which enables significantly improved performance for separation and mixing applications particularly with respect to distillation, liquid-liquid contacting, and heat exchange applications.

A packing (200, 300, 400, 500) for a rotating packed bed (RPB). The packing includes an elongate central aperture (210, 340, 440, 540). The elongate central aperture (210, 340, 440, 540) extends along at least part of the length of the packing (200, 300, 400, 500). The packing (200, 300, 400, 500) is configured to rotate about an axis (220, 350, 450, 550) which extends along the length of the central aperture (210, 340, 440, 540). A packing body (230, 360, 430, 530) extends around the central aperture (210, 340, 440, 540). The packing body (230, 360, 430, 530) includes a first body portion (240, 310, 420, 520) having a first side profile (250, 320, 410, 510). The packing body (230, 360, 430, 530) further includes a second body portion (260, 370, 460, 560) having a second side profile (270, 380, 470, 570), wherein the second side profile (270, 380, 470, 570) is different from the first side profile (250, 320, 410, 510).
