Assemblies, apparatuses, and methods to extract or convey a material from a source of the material may include a vacuum generation and sound attenuation assembly and a material receiver to enhance conveyance the material from the source of the material. The vacuum generation and sound attenuation assembly may include a vacuum source positioned to cause a vacuum flow between the source of the material, the material receiver, and the vacuum generation and sound attenuation assembly. The vacuum generation and sound attenuation assembly may further include a sound attenuation chamber positioned to receive at least a portion of the vacuum flow from, and attenuate sound generated by, the vacuum source. The material receiver may be positioned an elevated location relative to a source of the material and be capable of staging and metering the conveyance of material when moving material at the top of a structure, such as a refinery tower.

A mass-flow hopper that stores solid particulates and provides gas assistance to readily discharge the particulate matter. The mass flow hopper has an upper conical section connected via an intermediate section to a lower conical section having a lower discharge orifice. The lower conical section has a frustoconical configured gas impermeable wall lined with a gas permeable fluidizing plate spaced therefrom to define a lower space. The upper conical section slope is steeper than the lower frusto-conically configured gas permeable wall slope. Gas injected into the lower space passes from the lower space through the gas permeable fluidizing plate into the hopper to form a fluidized layer of gas between the solid particulates in the hopper and the gas permeable fluidizing plate. The fluidized layer of gas reduces wall friction within the lower conical section to facilitate discharging the particulates from the hopper.

A solid particle distribution controller includes a plurality of division plates proximate a division between an upstream solid particle conveyance pipe and a plurality of downstream pipes. The solid particle distribution controller also includes a plurality of extension plates. Each of the extension plates is movably mounted proximate to a respective division plate for movement in an upstream and downstream direction with respect to the division plate. The plurality of extension plates are configured and adapted for motion in the upstream and downstream direction independent of one another to extend upstream of the division plates as needed to improve solid particle distribution among the downstream pipes.

A slide plate 10 for a slide 1 for Geldart group C materials with a longitudinal axis 2, an up-facing surface 11 for supporting the Geldart group C material, a lower surface 13, a front-side surface 12 and a rear-side surface 14 may have a significantly reduced slope if the slide plate 10 is made of a ceramic refractory, wherein the slide plate has a number of through holes 20 providing a fluid communication between fluid inlets 23 in the lower surface 13 and fluid outlets 21 in the up-facing surface 11.
