摘要： An olefin polymerization process and apparatus wherein a fluid slurry comprising monomer, diluent and catalyst is circulated in a continuous loop reactor by two or more pumps. The process and apparatus allow operating the reaction at significantly higher solids content in the circulating fluid slurry. In a preferred embodiment, the fluid slurry is circulated by two impellers arranged so that the downstream impeller benefits from the rotational energy imparted by the upstream impeller. An olefin polymerization process operating at higher reactor solids by virtue of more aggressive circulation has improved efficiencies, particularly in larger-volume reactors.

摘要： An axial pump system cooperative with an elbow or other pipe section improves conversion of tangential to axial flow of a slurry flowing through a loop reactor by including both primary and secondary outlet guide vanes in the pipe section. The secondary guide vanes have “see through” access from the outlet end of the pipe section, while the primary guide vanes have “see through” access from the inlet side of the pipe section. Pump energy efficiency is improved, and friction of polymer particles on the reactor loop and pump sidewalls is reduced, thereby reducing the amount of polymer decay and increasing the percentage of useable and saleable product obtained from the reactor. Guide vanes can be straight or curved. Curved guide vanes can have inlet angles approximating the absolute flow angle of the fluid, and/or outlet angles approximating 0 degrees relative to the meridianal axis of the pipe section.
摘要翻译：与弯管或其他管段协作的轴向泵系统通过在管段中包括主出口导流叶片和次出口导向叶片来改善流过环流反应器的浆料的切向与轴向流动的转化。次级导向叶片从管段的出口端看到通过的通道，而主导叶片从管段的入口侧看到通过通道。提高泵的能量效率，降低反应器回路和泵侧壁上的聚合物颗粒的摩擦，从而减少聚合物衰减的量并增加从反应器获得的可用和可销售产品的百分比。导叶可以是直的或弯曲的。弯曲的导向叶片可以具有接近流体的绝对流动角的入口角和/或相对于管段的子午线轴线接近0度的出口角度。

摘要： A device for reducing solids and increasing pressure in a fluid handling system has comminution and inducer sections in a housing upstream of a pump impeller. A rotor has a hub with a small inlet diameter and a larger outlet diameter and a helical rotor blade with its blade pitch angle progressively increasing from inlet to outlet as a polynomial function. The comminutor section has a larger diameter than the inducer section and comminutor vanes extending inward forming a vane edge effective diameter equal to the inducer section diameter. The rotor blade turning within the closing fitting cage of vane edges provides a crushing and shearing action to solids in the fluid flow. Cutouts on the blade edge provide additional crushing and shearing action against the vanes. The fluid passageway sectional area at the outlet is bigger than the throat of the downstream main impeller.
