Abstract

Det er beskrevet en fremgangsmåte for å kontrollere driften av en kondensasjonsprosess for naturgass (LNG) hvor det anvendes gassturblndrevne kjølekompressorer (205), et tllførselskontrollsystem kompenserer for virkningene av endringer l omgivende lufttemperatur på anleggets driftseffektivitet ved periodisk å predikere en ny temperatur og endre settpunktene til hoved- tilbakemeldingskontrollerne l forventning om denne nye temperaturen og derved optimalisere driften av anlegget og minimalisere det spesifikke brenristofforbruket ved en gitt produksjonsmengde (LNG).
