Patent number: 10315176Abstract: A reactor comprises an outer sidewall and a bottom wall enclosing a hollow chamber comprising a lower fluidized bed zone and an upper freeboard zone. A plurality of inlets is provided for injecting at least one fluidizing medium into the fluidized bed zone and creating a swirling flow. At least one feed inlet communicates with the fluidized bed zone; and at least one product outlet is provided for removing a product from the chamber, the outlet(s) communicating with either the fluidized bed zone or the freeboard zone. The reactor has at least one internal barrier located inside the hollow chamber, and at least partly located in the fluidized bed zone. The internal barrier(s) have at least one opening within the fluidized bed zone, such as an underflow opening, to permit internal recirculation of material from the product zone to the feed zone, thereby simplifying reactor structure.Type: GrantFiled: May 8, 2015Date of Patent: June 11, 2019Assignee: HATCH LTD.Inventors: Kamal Adham, Christopher Thomas Harris, Alexandre Kokourine

Patent number: 10266625Abstract: Provided in the present invention are an olefin polymerization apparatus and an olefin polymerization process. The following operations and effects can be realized by the apparatus or method provided in the present invention: the gas material discharged from the polymerization reactor is condensed, after the gas-liquid separation, the resulting gas portion is recycled to the reactor to form a circulation loop; the condensate can be selectively introduced to the polymerization reactor, in order to achieve the free switch between the homopolymerization reaction and the copolymerization reaction or between different copolymerization reactions, and at the same time the condensate can absorb the heat generated by the reaction. By using the apparatus and method provided in the present invention, polyolefin products having excellent mechanical properties and processability can be prepared as needed.Type: GrantFiled: December 9, 2015Date of Patent: April 23, 2019Assignees: China Petroleum & Chemical Corporation, Zhejiang UniversityInventors: Jingdai Wang, Wenqing Wu, Yongrong Yang, Guodong Han, Zhengliang Huang, Jingyuan Sun, Xiaofei Wang, Xiaoqiang Fan, Huanjun Du, Binbo Jiang, Zuwei Liao, Yao Yang

Patent number: 10113019Abstract: The number of small gels that form in polyolefin thin films may be reduced by altering certain production parameters of the polyolefin. In some instances, the number of small gels may be influenced by the melt index of the polyolefin. However, in many instances, melt index is a critical part of the polyolefin product specification and, therefore, is not manipulated. Two parameters that may be manipulated to mitigate small gel count while maintaining the melt index are polyolefin residence time in the reactor and ICA concentration in the reactor.Type: GrantFiled: November 24, 2015Date of Patent: October 30, 2018Assignee: Univation Technologies, LLCInventors: Bruce J.
