摘要： A polymerization loop reactor including a loop reaction zone, a continuous takeoff, and a fluid slurry disposed in the reaction zone. A generally cylindrical wall defines the loop reaction zone. The length of the loop reaction zone and the nominal outside diameter of the generally cylindrical wall define a length/diameter ratio greater than 250. The reactor can be charged with a fluid slurry including an olefin monomer reactant, solid olefin polymer particles, and a liquid diluent. The concentration of the solid olefin polymer particles in the slurry can be greater than 40 weight percent based on the weight of polymer particles and the weight of liquid diluent. Also disclosed is a polymerization process carried out by polymerizing, in the loop reaction zone of a reactor as defined above, at least one olefin monomer in a liquid diluent to produce a fluid slurry as defined above.

摘要： A process and apparatus for passing a polymerization effluent, comprising solid polymer, unreacted monomer, diluent and minor amounts of contaminants, to a high pressure flash where most of the fluid components are flashed and wherein a slip stream comprising diluent and minor amounts of monomer is separated from the bulk of the flashed fluid components. The slip stream is subjected to olefin removal to give an essentially olefin-free stream for recycle to a catalyst mud preparation area. The bulk of the flashed fluid components are recycled directly back to the polymerization zone without expensive olefin removal, although treatment to remove other contaminants can optionally be performed. The polymer and entrained fluid is passed to a low pressure flash zone where the fluids are flashed off, compressed and joined with the flash from the high pressure flash tank. Because the bulk of the fluids are removed in the high pressure flash, compression and cooling of product fluids prior to recycle is kept to a minimum.
摘要翻译：一种将含有固体聚合物，未反应单体，稀释剂和少量污染物的聚合流出物通到高压闪蒸的方法和装置，其中大部分流体组分被闪蒸，并且其中包含稀释剂和少量单体的滑流是与大部分闪烁的流体组分分离。将滑流进行烯烃除去，得到基本上无烯烃的物流，用于再循环到催化剂泥浆制备区域。大部分闪蒸的流体组分直接回收到聚合区，而不需要昂贵的烯烃去除，尽管可以任选地进行除去其它污染物的处理。聚合物和夹带的流体被传递到低压闪蒸区域，其中流体被闪蒸掉，压缩并与来自高压闪蒸罐的闪光接合。因为大部分流体在高压闪蒸中被除去，所以在再循环之前将产品流体的压缩和冷却保持在最小。
