Abstract

Oppfinnelsen vedrører en fremgangsmåte for bestemmelse av en konsentrasjon av en anionisk ladet vannoppløselig kjelevannbehandlingspolymer i et kjelevannsystem. Kje- levannsystemet omfatter en kilde for en matevannstrøm til systemet som første systemparameter, en kilde for en avblåsingsstrøm fra systemet som andre systemparame- ter samt en kilde for oppløselig polymer i kjelevannet som tredje systemparameter. Den oppløselige polymer gjennomgår en hydrotermal reaksjon ved driftbetingel- sene for kjelevannsystemet. Den oppløselige polymer inneholder minst 0,01% merenheter av spektrofotometrisk utstrålende grupper som er bundet til polymerkjeden. Fremgangsmåten omfatter trinnene å: a) måle minst ett spektrofotometrisk kjennetegn av den oppløselige poly- mer som foreligger i en prøve av kjelevannet; b) omdanne kjennetegnet til et elektrisk signal som til- svarer konsentrasjonen av den oppløselige polymer i kjelevannet; c) sammenligne det elektriske signal som tilsvarer konsentrasjonen av den oppløselige polymer i kjelevannet, med et elektrisk signal som tilsvarer en ønskelig konsentrasjon av den oppløselige polymer i kjelevannet; og deretter d) bestemme en anrikning eller et tap av den oppløselige polymer i kjelevannet.
