A hydrocarbon recovery system is integrated with a fluff transfer system. The hydrocarbon recovery system is configured for contacting a wet polymer fluff with a purge gas to provide a purged polymer fluff and an overhead stream, and separating a solids stream, a recovered hydrocarbon stream, and a recovered purge gas from the overhead stream. The polymer fluff transfer system is configured to receive the purged polymer fluff from the hydrocarbon recovery system and transport the purged polymer fluff in the fluff transfer system via circulation of a fluff transfer gas. The hydrocarbon recovery system and the fluff transfer system are integrated by utilizing fluff transfer gas from the fluff transfer system as the purge gas in the hydrocarbon recovery system and/or by utilizing at least a portion of the recovered purge gas from the hydrocarbon recovery system in the fluff transfer system as the fluff transfer gas.

A dust filtering and collection system for filtering dust and other debris particles from an incoming dust laden air stream, such air stream generally being used for conveying granular material into or from a bulk tank trailer, a railroad car, or other conveying vehicle, the filtering system designed to be functioned by vacuum air pressure, operatively generated by a blower, to draw in the soiled air into the filter system, to cleanse such air for further use in the conveying of the granular material. The air flow may be reversed, to provide for a dislodging of any dust particles from the filtering system, and to cleanse the filter for further efficient usage of the system in conveying granular material into or out of the tank trailer, or other vehicle during usage. The filter system includes a pod of filter tubes encapsulated by a polymer header that mounts to a transverse plate that secures to the approximate upper end of the filter canister of the filtration system.

An exhaust system of an agricultural product container includes a first media screen configured to be coupled to the agricultural product container. The first media screen includes a first plurality of apertures. The first media screen is configured to block a granular product from entering the exhaust system and enabling an air flow into the exhaust system. The exhaust system includes a diffuser having a first diffuser aperture configured to diffuse the air flow in a downward direction. The exhaust system further includes a passage fluidly coupled between the first media screen and the diffuser. The passage is configured to selectively guide the air flow from the first media screen toward the diffuser.

A hopper loader having a hopper connected to a vacuum source for applying a vacuum to the hopper to convey material into the hopper through a material inlet. A material separator is disposed between the material inlet and the vacuum source for filtering the material. A material discharge assembly is connected to the hopper and disposed for controlling downwardly gravity flow of the material from the hopper, the material discharge assembly having a material outlet configured to be opened and closed to control the discharge of material from the hopper. A vacuum detector is disposed between the material separator and the vacuum source. A vacuum activated control operatively connected to the vacuum detector and configured to turn off the vacuum source in response to a signal from the vacuum detector.

A pneumatic conveyance system includes at least one filtration component and a cage assembly disposed within the filtration component. The cage assembly may include a first cage, a second cage, and an actuator, where the actuator may be configured to move the first cage relative to the second cage and cause at least a portion of the first cage to rub against a filtration component within the pneumatic conveyance system. A method of dislodging material buildup within a pneumatic conveyance system includes causing a first cage of a cage assembly to move relative to a second cage within a filtration component.

An additive manufacturing powder handling system includes a powder container and at least two of: an overflow powder collector system configured to collect overflow additive manufacturing powder from the additive manufacturing printer and pass the overflow additive manufacturing powder into the powder container; a vacuum system configured to receive by vacuum force additive manufacturing powder from an additive manufacturing printer and pass the additive manufacturing powder into the powder container; a sieve system configured to filter the additive manufacturing powder; and a powder container moving apparatus configured to move the powder container between any two of the additive manufacturing printer, the overflow powder collector system, the vacuum system, and the sieve system. The powder container includes a powder container coupling. Each of the overflow powder collector system, the vacuum system, and the sieve system includes at least one coupling element configured to receive the powder container coupling.
