Abstract

Fremgangsmåte for bestemmelse av pE-tltrerlngskurver for bruk l adaptlv regulering av pH i en prosess, om- fattende oppsamling av datapunkter som hver represen- terer forholdet mellom en reagens tilsatt til prosessen og en strømningsmengde til prosessen ved en målt pH, lagring av datapunktene l et "blnd"-system Ifølge pH- verdl, og anvendelse av de lagrede datapunkter for å tilveiebringe en modell av tltrerlngskurven for bruk ved regulering av tilsetningen av reagens. Eldre punkter erstattes med nyere punkter under prosessen for kontinuerlig å oppdatere modellen. Modellen ble benyttet for å utvikle en forsterknlngsfordellng for operasjon av en Pl-regulator som benyttes ved til- setning av en reagens til prosessen.
