| titleOfInvention | Activity monitoring and polymerization process control |
| abstract | The present invention relates to a method for controlling a liquid feed stream, which measures at least one spectrum of a liquid feed stream comprising an initiator or a catalyst and determines its activity using a prediction model based on said spectrum. This is accomplished by adjusting the feed stream and / or the production conditions of the feed stream comprising the initiator or catalyst to achieve or maintain the desired level of total activity. In another aspect, the invention relates to a controlled process for polymer production in a polymerization reactor that is conducted in contact with a liquid feed stream comprising a monomer and an initiator or catalyst, and the feed stream entering the polymerization reactor and / or Alternatively, control of the initiator or catalyst production can be measured by measuring at least one spectrum of the liquid feed stream containing the initiator or catalyst, determining its activity using a prediction model based on said spectrum, and selecting the desired in the polymerization reactor. This is done by adjusting the feed stream and / or the production conditions of the feed stream containing the initiator or catalyst to achieve or maintain a level of total activity. More specifically, the present invention relates to a method for controlling the activity of an aluminum-containing initiator in a copolymerization process of isoolefins and multiolefins, particularly isobutylene and isoprene. The invention further relates to an apparatus and chemical plant suitable for performing the process. |
