2. Patenttivaatimuksen 1 mukainen menetelmä, tunnettu siitä, että selluloosamassasta poistetaan vettä (PI, P2) 25 kuiva-ainepitoisuuteen 25-35 paino-%.
3. Patenttivaatimuksen 1 tai 2 mukainen menetelmä, tunnettu siitä, että selluloosamassasta (2, 3) poistetaan vettä (PI, P2) puristamalla siitä nestettä. 30
4. Patenttivaatimuksen 1, 2 tai 3 mukainen menetelmä, tunnettu siitä, että haihdutus (EV) suoritetaan useissa rinnan tai sarjaan kytketyissä vaiheissa.
5. Patenttivaatimuksen 4 mukainen menetelmä, tunnettu siitä, että haihdutus (EV) suoritetaan lämpötilassa, joka on alle 70°C. 12 85293
6. Jonkin edellisen patenttivaatimuksen mukainen menetelmä, tunnettu siitä, että haihtunutta höyryä uudelleen-komprimoimalla saatu kondensaatti (10) palautetaan ainakin osittain haihdutuksesta (EV) johonkin seuraavaan valkaisu- 5 vaiheeseen (E) käytettäväksi pesuvetenä.
7. Jonkin edellisen patenttivaatimuksen mukainen menetelmä, tunnettu siitä, että haihdutus (EV) suoritetaan niin korkeaan kuiva-ainepitoisuuteen, että haihdutusjäännös (17) 10 voidaan kuivattaa tai polttaa (IN) epäorgaaniseksi aineeksi (20, 22).
8. Jonkin edellisen patenttivaatimuksen mukainen menetelmä, tunnettu siitä, että toisesta vedenpoistosta (P2) 15 peräisin oleva neste palautetaan mainittuun ensimmäiseen valkaisuvaiheeseen (DC), joka suoritetaan klooripitoisilla valkaisukemikaaleilla.
