Patent

CA 2136876

In a polymerization process utilizing a high pressure flash to separate polymer from unreacted monomer contained in the effluent stream from the reactor, the concentration of unreacted monomer in the reaction effluent is determined by withdrawing from the reactor an effective analyzing amount of effluent, exposing the amount to a low pressure flash and analyzing the vaporized portion to determine the concentration of monomer.

Dans un procédé de polymérisation utilisant un éclair haute pression pour séparer un polymère du monomère n'ayant pas réagi, présent dans l'effluent d'un réacteur, la concentration du monomère n'ayant pas réagi dans cet effluent est mesurée en retirant du réacteur une quantité suffisante d'effluent pour l'analyse, en l'exposant à un éclair basse pression et en analysant la fraction vaporisée pour déterminer la concentration de monomère.
