摘要： A method for preparing a titanium-containing Ziegler-Natta catalyst is disclosed. A dialkyl magnesium compound, a trialkyl aluminum compound, and a polymethylhydrosiloxane are first combined in a hydrocarbon solvent. That product is then combined with dry, alcohol-free magnesium chloride. A solid product from the reaction with the magnesium chloride component is isolated and washed with a hydrocarbon solvent. The washed solid product is then combined with an alkyl aluminum dichloride or a dialkyl aluminum chloride to give the catalyst. The catalyst is suitable for both slurry and gas-phase olefin polymerizations. Polyolefins produced with the catalyst have broad molecular weight distributions and narrow distributions of relatively large particles.

摘要： Multimodal polyolefin polymers may be prepared in series-connected polymerization reactors where a prior reactor is a slurry reactor employing light solvent as the slurry medium and hydrogen to limit polymer molecular weight, the polymer product from the prior reactor being substantially freed of hydrogen prior to entry into a subsequent polymerization reactor operating at low hydrogen pressure to produce a high molecular weight olefin. The economics and operating performance of such a series slurry reactor polyethylene process can be significantly improved through the use of an intermediate slurry transfer system and hydrogen removal apparatus that employs flash drums in series in conjunction with a warm recycle solvent slurry diluent.

摘要： A disengagement vessel employing a lock hopper effectively reduces concentration of non-polymer-associated components in the polymer product slurry of a first olefin slurry polymerization reactor, allowing cascading of a second slurry polymerization reactor operating at lesser concentration of comonomers, hydrogen, and other components to produce multicompositional polyolefin polymers and/or polymers having a multimodal monomer distribution, e.g. diblock polymers having substantially non-overlapping comonomer contents between the blocks.

摘要： A method for monitoring the mechanical condition of a reciprocating compressor having a packed-plunger cylinder is provided. An end assembly is attached to one end of the cylinder, and the strain of at least one component of the end assembly is measured as the plunger reciprocates within the cylinder. The measured strain is correlated with a crank angle to facilitate generation of a strain profile. Two pressure values related to the pressure in the cylinder are determined when the plunger is at two different locations. This facilitates generation of a cylinder pressure profile based on the correlated measured strain. The cylinder pressure profile is thus generated without the use of intrusive gauges or sensors, which may create a leak path, or create a stress concentration in the wall of the cylinder.
摘要翻译：提供了一种用于监测具有填充柱塞缸的往复式压缩机的机械状态的方法。端部组件附接到气缸的一端，并且当柱塞在气缸内往复运动时测量端部组件的至少一个部件的应变。测量的应变与曲轴角度相关，以便于产生应变曲线。当柱塞在两个不同的位置时，确定与气缸中的压力相关的两个压力值。这有助于基于相关测量应变产生气缸压力分布。因此，不使用可能产生泄漏路径的侵入式量规或传感器产生气缸压力分布，或在气缸的壁中产生应力集中。
