摘要： In a gas phase fluidized bed polymerization process for the production of polyolefin polymers, such as polyethylene polymers or polypropylene polymers, loss of ethylene or propylene accompanying inert gas purging is reduced by passing an ethylene- or propylene- containing purge stream through a vent column to contact a hydrocarbon liquid flowing through the vent column contercurrent to the purge stream whereby unreacted ethylene or propylene in the purge stream portion is dissolved in the hydrocarbon liquid to produce an ethylene- or propylene- enriched liquid stream and an ethylene- or propylene- depleted gaseous stream. The ethylene- or propylene- enriched liquid stream is then recycled to the fluidized bed reactor, while at least part of the ethylene- or propylene- depleted gaseous stream is purged.

The head member may have a substantially conical shape and taper away from the at least one shoulder when present. The design of the head member/elongated body should accomplish lower pressure drop and avoid stagnant flow of the material. The number of holes that are required (affected by flow per hole requirement) will likewise affect the shape (length) to accommodate the hole count. The head member may comprise a tip and a tapered support member. The tip may have a polygon or a polyhedron shape or a pentagon or hexagon shape. The tip may have a raised surface and the raised surface may be substantially conical in shape.

摘要： A method for determining initial conditions for a transition from an initial reaction to a target reaction to minimize (or substantially minimize) the amount of off-grade material produced during the transition, and optionally also process control variables for implementing the transition. A product property that can cause production of more off-grade product during the transition than can any other of the properties is identified as a primary property, and process control variables for implementing the transition are determined so that the product produced during the transition goes off-grade due to the primary property, and due to each of at least one other product property, at the same or substantially the same time, and preferably also so that each non-primary property reaches a value compliant with the target specification set as late as possible but not later than the time the primary property reaches a value compliant with the target specification set.
