Abstract

Tämä keksintö koskee menetelmää nestevirtauksien käsittelemiseksi sellutehtaassa. Menetelmässä tuotetaan valkaisematonta massaa ruskean massan valmistusyksikössä (20), annostellaan valkaisemattoman massan virtaukseen ensimmäistä hapotuskemikaalia hapotusvaiheessa (26) ainakin osan valkaisemattoman massan virtauksessa olevista fosforiyhdisteistä liuottamiseksi, muodostetaan fosforiyhdisteitä sisältävä suodos, poistetaan valkaisemattoman massan virtauksesta ainakin osa mainitusta fosforiyhdisteitä sisältävästä suodoksesta fosforinpoistovaiheessa (27), ja valkaistaan valkaisematon massa valkaisuyksikössä (30). Keksintö koskee lisäksi järjestelmää nestevirtauksien käsittelemiseksi sellutehtaassa.
