Abstract: Disclosed are embodiments of a method of regenerating a desiccant in an off-line treater of a polyolefin production process. The method may include a heating phase followed by a cooling phase. The heating phase may involve use of a regenerating gas made from heating a treated a recycle stream of the polyolefin production process to regenerate desiccant in an off-line treater. The cooling phase may involve thermosyphoning the regenerating gas, nitrogen, an olefin-free diluent, or combinations thereof in a closed-convection loop of the off-line treater.

Abstract: A manufacturing system for producing polyolefin includes a polymerization reactor, a flash chamber, and a purge column. In certain embodiments, the purge column may receive a solids stream directly from the flash chamber. Further, the purge column may function as a feed tank for an extruder within an extrusion/loadout system. According to certain embodiments, the manufacturing system may be configured to consume less than 445 kilowatt-hours of energy per metric ton of polyolefin produced based on consumption of electricity, steam, and fuel gas.

Abstract: Processes for producing an activated chromium catalyst are disclosed, and these processes comprise contacting a supported chromium catalyst with a gas stream containing from 25-60 vol % oxygen at a peak activation temperature of 550-900° C. to produce the activated chromium catalyst. The linear velocity of the gas stream is 0.18-0.4 ft/sec, and the oxygen linear velocity of the gas stream is 0.05-0.15 ft/sec. The resultant activated chromium catalyst and an optional co-catalyst can be contacted with an olefin monomer and an optional olefin comonomer in a polymerization reactor system under polymerization conditions to produce an olefin polymer.

Abstract: A reactor system containing one or more loop reactors for olefin polymerization is provided. The loop reactors include vertical sections, elbow sections, and/or horizontal sections connected into one or more loop reaction zones to polymerize an olefin monomer in the presence of a liquid diluent into a slurry comprising particles of a polyolefin polymer. The reactor system footprint is reduced to increase production efficiency and save cost, while maintaining a high processing capacity. In one embodiment a horizontal length (LH) of at least one horizontal section is greatly reduced with maintained processing capacity. In another embodiment, at least one elbow section of the reactor system is configured to maintain a Dean number (Dn) of the slurry flowing therein to be higher than 3,000,000.
