Abstract: Apparatuses and processes that produce multimodal polyolefins, and in particular, polyethylene resins, are disclosed herein. This is accomplished by using two reactors in series, where one of the reactors is a multi-zone circulating reactor that can circulate polyolefin particles through two polymerization zones optionally having two different flow regimes so that the final multimodal polyolefin has improved product properties and improved product homogeneity.

Abstract: Processes for producing circular polyalphaolefins and polyalphaolefin-based products from used oils include the steps of introducing a used oil composition, or a feedstock containing a used oil composition and at least one other liquid, fuel, or oil, to a cracking unit to produce ethylene, oligomerizing the ethylene to form desirable normal α-olefins, oligomerizing the normal α-olefins into oligomers thereof, and hydrogenating the oligomers to form polyalphaolefins. The polyalphaolefin is mixed with additives and/or other oils to result in a product composition, which can be used in various end-use applications and then recycled into the process. In accordance with International Sustainability and Carbon Certificate standards, the product composition can be defined as circular, bio-circular, or bio- as determined by the mass balance attribution and/or the free attribution approach.

Abstract: Methods of controlling olefin polymerization reactor systems may include a) selecting n input variables, each input variable corresponding to a process condition for an olefin polymerization process; b) identifying m response variables corresponding to a measurable polymer property; c) adjusting one of more of the n input variables using the olefin polymerization reactor system and measuring each of the m response variables as a function of the input variables for olefin polymers; d) analyzing the change in each of the response variables as a function of the input variables to determine coefficients; e) calculating a Response Surface Model (RSM) for each response variable determined in step d); f) applying n selected input variables to the calculated RSM to predict one or more of m target response variables; and g) using the n selected input variables to operate the olefin polymerization reactor system and provide a polyolefin product.

Abstract: The present disclosure relates generally to a system having a reactor system with a polymerization reactor and a feed system fluidly coupled to a feed inlet of the reactor. The feed system supplies components to the reactor via the feed inlet, and the reactor has a flow path that continuously conveys the components through the reactor and subjects the components to polymerization conditions to produce a polymer. The system also has an analysis system coupled to the reactor for online monitoring of a particle size of the polymer. Further, the system includes a control system, coupled to the analysis and feed systems, that receives a signal from the analysis system indicative of the monitored particle size of the polymer and adjusts an operating parameter of the feed system to control a flow rate of at least one of the components to the reactor based at least on the signal.
