Assemblies and methods to extract materials from a retention collection may include a vacuum source including a series of vacuum generators configured to generate a vacuum flow to create a suction between the retention collection and a material collector for extraction of the material from the retention collection and transfer to the material collector. The suction generated by the vacuum flow will be sufficient to draw-in and convey the material in liquid, semi-solid and substantially solid states from the retention collection along a collection conduit and into the material collector for disposal. The vacuum generation assembly may include a filter and sound attenuation chamber connected to the vacuum source configured to receive and filter a vacuum exhaust fluid/air flow portion of the vacuum flow and to attenuate sound generated by the vacuum source.

A system, method, and apparatus for ameliorating deposits in selective catalytic reduction systems for the reduction of nitrogen oxide emissions in steam methane reformers. The system includes positioning a dual stage refractory particulate (RP) filter placed in an upstream airflow from a Selective Catalytic Reduction System (SCRS). The first stage is formed of a perforated steel plate with a second stage formed of a wire mesh screen. The system may employ air cannons to clean each of the first stage and the second stages.

A filter device collects and stores brake particles generated by a friction brake. The filter device can be regenerated. The filter device determines that at least one boundary condition that makes it possible and/or permits the execution of regeneration of the filter device is met. In response to the determination, brake particles stored in the filter device are to be removed from the filter device.

A particle separator for the separation of solid particles out of a flowing fluid, the input mass flow, which is characterized in that a particle chamber for concentrating the solid particles to be separated is disposed in the flow path of the input mass flow and that at least one region of the wall of the particle chamber is implemented as a filter element through which a primary mass flow of the fluid can flow and that, additionally, at least one bypass opening is disposed in the wall of the particle chamber for the through-flow of the fluid with a secondary mass flow at higher filtration resistance.

A separator for a cleaning device, the separator comprising: a housing that encloses a separating volume, the housing comprising an inlet for receiving a fluid flow containing entrained debris into the separating volume, and an outlet for discharging a filtered fluid flow output from the separating volume; a filter screen disposed on or in the housing to define part of a boundary of the separating volume, the filter screen being configured to retain the debris in the separating volume while allowing air to exit the separating volume to flow to the outlet; and a cleaning conduit configured to convey fluid towards the filter screen, the cleaning conduit comprising a jet-forming outlet that is configured to direct a fluid jet at or across the filter screen to remove debris attached to the filter screen.
