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.

This invention relates to a robotic device 10.1, 10.2 and method for handling catalyst material 106, 206 in a reactor 100 by removing spent catalyst from the reactor and/or loading the reactor with fresh catalyst without an operator having to enter an interior of the reactor which increases operator safety. The robotic device includes a body 12, which is configured to engage a flange 104 of the reactor, and a handling arm which is configured for use both as a cleaning arm 18 and a loading arm 218. The handling arm is connected to the body and is angularly and longitudinally displaceable relative to the body. The handling arm has a segment which is telescopically extendible/retractable relative to the body. When used as a cleaning arm, the arm receives a vacuum line for removing catalyst. When used as a loading arm, a telescopic loading sleeve is connected to the segment.
