    • 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 aluminium containing initiators in a process for the co-polymerisation 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,本发明涉及在异烯烃和多烯烃,特别是异丁烯和异戊二烯的共聚合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 including an always-available theft protection system is described. In one embodiment, the system comprises an arming logic to arm the platform, when an arming command is received, a risk behavior logic to detect a potential problem when the platform is armed, and a core logic component to provide logic to analyze the potential problem, and to move the platform to a suspecting mode, when the potential problem indicates a theft suspicion. The system, in one embodiment, further comprises configuration logic to configure settings for the system when the platform is in an unarmed mode, the configuration logic including a user logic enabling an authorized user to alter settings and an administrator logic enabling an administrator to alter the settings using an authenticated set request.
