Abstract

Oppfinnelsen omhandler en fremgangsmåte for å bestemme prosessparametere i en kjemisk prosess utført i en kjemisk reaktor (2). Den omfatter å lede en prøve med prosessmedium av nevnte kjemiske prosess inn i en sidesløyfe (20, 22, 24, 26, 34, 40, 42, 36) og isolere nevnte sidesløyfe fra prosessmediet. Prøven sirkuleres i nevnte sidesløyfe og tempereres (46) til en ønsket temperatur. En måling (38) av minst en prosessparameter gjøres på nevnte prøve ved den ønskede temperaturen. Oppfinnelsen omhandler også et system for å utføre fremgangsmåten og anvendelsen av denne, for eksempel kontrollert fremstilling av harpikser. ?? ?? ?? ??The invention relates to a method for determining process parameters in a chemical process carried out in a chemical reactor (2). It comprises conducting a sample of process medium of said chemical process into a side loop (20, 22, 24, 26, 34, 40, 42, 36) and isolating said side loop from the process medium. The sample is circulated in said side loop and tempered (46) to a desired temperature. A measurement (38) of at least one process parameter is made on said sample at the desired temperature. The invention also relates to a system for carrying out the method and application thereof, for example controlled production of resins. ?? ?? ?? ??
