摘要： A process for polymerizing one or more olefins in a gas-phase polymerization reactor is provided. The gas-phase reactor has a fluidized bed and a fluidizing medium. The fluidizing medium has an operating density and an operating velocity. The process includes determining a critical gas velocity and/or determining a critical gas velocity for the polymerization. The operating gas density and/or the operating gas velocity for the fluidizing medium is then adjusted to be less than or equal to its respective critical value. The process includes increasing the bulk density of the fluidized bed. The increase in the fluidized bed bulk density increases productivity without increasing reactor residence time.

摘要： A rotating breech lock rotates tubing to distribute wear caused by a rotating or reciprocating rod of an artificial lift system. The rotating breech lock has a spool that disposes on a wellhead. A bowl element disposes in the spool's bore, and a hanger fits into the spool and lands on the bowl element with a thrust bearing. Above the hanger, a load ring fits against the hanger with a bearing, and a hold-down sleeve and locking pins hold the load ring against the hanger. The spool has a worm that mates with a wheel defined about the hanger so turning the worm by a ratchet or other mechanism rotates the hanger. Internally, the hanger has a bore with opposing shoulders separated by gaps. A mandrel couples to the tubing and disposes up into the hanger. Protrusions or keys on the hanger can selectively align with the gaps and the shoulders depending on how the mandrel is rotated in the hanger bore.
