    • The present invention relates to a method to control a liquid feed stream carried out by measuring at least one spectrum of the liquid feed stream comprising an initiator or catalyst, determining its activity using a predictive model on the basis of said spectrum and adjusting the feed streams and/or the preparation conditions of the feed stream comprising the initiators or catalysts in order to attain or maintain a desired level of total activity. In a further aspect the invention relates to a controlled process for the preparation of polymers in a polymerization reactor by contacting liquid feed streams comprising monomers and initiators or catalysts, whereby the control of the feed streams entering the polymerization reactor and/or the initiator or catalyst preparation is carried out by measuring at least one spectrum of the liquid feed stream comprising an initiator or catalyst, determining its activity using a predictive model on the basis of said spectrum and adjusting the feed streams and/or the preparation conditions of the feed stream comprising the initiators or catalysts in order to attain or maintain a desired level of total activity within the polymerization reactor. More particularly, the invention relates to a method for controlling the activity of aluminum containing initiators in a process for the co-polymerization of isolefins and multiolefins, in particular isobutylene and isoprene. The present invention further to device and a chemical plant suitable to operate said process.
    • 本发明涉及一种控制液体进料流的方法,所述方法是通过测量包含引发剂或催化剂的至少一个光谱的液体进料物流,使用基于所述光谱的预测模型确定其活性并调节进料流 和/或包含引发剂或催化剂的进料流的制备条件以获得或保持期望的总活性水平。 在另一方面,本发明涉及通过使包含单体和引发剂或催化剂的液体进料流接触而在聚合反应器中制备聚合物的受控方法,由此控制进入聚合反应器和/或引发剂或催化剂的进料流 通过测量包含引发剂或催化剂的液体进料流的至少一个谱线,基于所述光谱使用预测模型确定其活性并调节进料流和/或进料流的制备条件来进行制备,所述进料流和/ 引发剂或催化剂,以获得或保持聚合反应器内所需的总活性水平。 更具体地说,本发明涉及在用于共聚烯烃和多烯烃,特别是异丁烯和异戊二烯的方法中控制含铝引发剂的活性的方法。 本发明还涉及适用于操作所述方法的装置和化学设备。

    • A platform protected by a system, the platform including a power source, is described. The system in one embodiment comprises a risk behavior logic to detect a potential problem, a core logic component to provide logic to analyze the potential problem and to trigger a security action logic to perform a security action, when the potential problem indicates a theft suspicion, and the security action logic to utilize a kill pill to disable the platform, when the platform has set a high security status authorizing use of a self-kill pill or the platform sends an alert and receives a remote instruction to utilize a remote kill pill.
    • 描述了由系统保护的平台,包括电源的平台。 在一个实施例中的系统包括用于检测潜在问题的风险行为逻辑,提供用于分析潜在问题的逻辑的核心逻辑组件以及当潜在问题指示盗窃嫌疑时触发安全动作逻辑执行安全动作的系统, 以及当平台已经设置了高度安全状态以授权使用自杀药丸时,利用杀死药丸来禁用平台的安全动作逻辑,或者该平台发送警报并且接收远程指令以利用远程灭杀药。
