Abstract

Menetelmä kemikaalien talteenottokattilan (100) ohjaamiseksi. Menetelmässä käsitellään keittolientä (102) kemikaalien talteenottokattilan (100) tulipesässä (105) keon (130) muodostamiseksi tulipesään, johdetaan sulaa (140) keosta sulakourun (145) kautta liuotussäiliöön (150), joka käsittää vesiliuosta (152), ja hajotetaan sula vesiliuoksen pinnan (155) yläpuolella hajotusfluidin (170) avulla. Menetelmässä lisäksi mitataan optisesti tai akustisesti ensimmäistä parametria, joka osoittaa ainakin joko [A] sulan (140) virtausta sulakourun (145) kautta tai [B] sulan (140) hajoamista; ja ensimmäisen parametrin perusteella ohjataan hajotusfluidin (170) virtausta. Kemikaalien talteenottokattila (100), joka soveltuu menetelmän toteuttamiseen.
