The present invention relates to an olefinic monomer recovery device capable of suppressing fouling and pressure drop in the recovery device in a process of separating and recovering unreacted monomers after production of a polyolefin resin. The olefinic monomer recovery device is used for separating and recovering unreacted olefinic monomers after production of a polyolefin resin, the apparatus comprising a vertical-type heat exchange unit, and a knock-out drum unit.

A wet/dry vacuum (1) having a bottom vertical discharge (13) located on a collection tank (2) and an elevated rolling stand (14) that allows the wet/dry vacuum and collection tank to be rolled over a bucket or toilet and emptied of any collected liquids. A strainer 13 and hinged attachment to the stand allows a user to easily empty hard debris from the wet/dry vacuum by simply tipping the collection tank over from its elevated position into a trash can.

A particle separation device to remove particulate matter from an exterior air flow for use with an environmental control system includes a curved airflow path with an inner radius and an outer radius, the curved air flow path to receive the exterior air flow, a particle passage disposed along at least one of the inner radius and the outer radius to receive the particulate matter from the exterior air flow, a circumferential volute to receive the particulate matter from the particle passage, and a duct to transport the particulate matter from the circumferential volute to a downstream region.

A downflow polymer product withdrawal system includes a withdrawal line to collect a product including a powder and a carrier gas. The line may include at least one downward sloped descending section and is absent of any non-self draining regions. The downflow system may further include a lock hopper, a fill valve between the line and the lock hopper, and a discharge valve downstream of the lock hopper. An upflow polymer product withdrawal system includes a withdrawal line to collect and discharge a product comprising a powder and a carrier gas. The line may include at least one non-vertical section including at least one upward sloped ascending section and at least one downward sloped descending section, and is absent of any non-self draining regions. The upflow system may further include a lock hopper, a fill valve between the line and the lock hopper, and a discharge valve.

An apparatus for separating a granular material from a conveying air stream (5) comprising a deflecting surface (2) for the laden conveying air stream (5) against which flow may take place substantially tangentially is described. In order to allow advantageous separation conditions, it is proposed that the deflecting surface (2) adjoins a guiding surface (3) curved in the opposite direction in the flow direction for a largely laminar flow separation.
