Abstract
Fremgangsmåte for gjenvinning av kjemikalier og energi fra celluloseavlut, fortrinnsvis svartlut som fås i sulfatcellulose-proses- sen, hvor avluten føres inn i en forgas- singsreaktor (1) for pyrolyse og delvis forbrenning, hvor en energirik gass dannes som inneholder partikler av uorganisk kjemi- kaliesmelte, gassblandingen føres ut av reaktoren (1) og blir på samme tid avkjølt ved injisering av et findelt kjølemedium, fortrinnsvis vann, i samband med avgangen fra reaktoren (1), blandingen av gass og ikke-klebrige kjemikaliepartikler føres fra et kjølekammer (2), anordnet i forbindelse med forgassingsreaktoren (1), til en separa- sjonsanordning (3), fortrinnsvis en syklon, hvor de ikke-klebrige kjemikaliepartikler separeres fra gassen, gasstrømmen, som stort sett er blitt renset for kjemikaliepartik- ler, tas ut via en øvre forbindelse på sepe- rasjonsanordningen (3), mens kjemikaliepar- tiklene tas ut via en nedre forbindelse på separasjonsanordningen (3) og smeltepartikl- ene som forlater reaktoren i gassblandingen avkjøles til en temperatur hvor de har i det minste delvis størknet og er blitt omdannet til fast fase slik at partiklene som er innlemmet i gassblandingen er ikke-klebrige, og hvor en etterfølgende v^rmeveksling av den separerte gass utføres fra et stort sett bibeholdt temperaturnivå.Process for recovery of chemicals and energy from cellulose effluent, preferably black liquor obtained in the sulphate cellulose process, where the effluent is fed into a gasification reactor (1) for pyrolysis and partial combustion, where an energy rich gas is formed containing particles of inorganic chemistry - potassium melt, the gas mixture is discharged from the reactor (1) and is cooled at the same time by injection of a finely divided refrigerant, preferably water, in connection with the exit from the reactor (1), the mixture of gas and non-sticky chemical particles is discharged from a cooling chamber ( 2), arranged in conjunction with the gasification reactor (1), to a separation device (3), preferably a cyclone, in which the non-sticky chemical particles are separated from the gas, the gas stream which has been largely purified of chemical particles is removed via an upper connection on the separation device (3), while the chemical particles are removed via a lower connection on the separation device (3) and melt portion The leaving the reactor in the gas mixture is cooled to a temperature at least partially solidified and converted to solid phase so that the particles incorporated in the gas mixture are non-sticky and a subsequent heat exchange of the separated gas is produced from a largely maintained temperature level.
