| titleOfInvention | Improvements in or relating to the treatment and oxidation of a melt obtained from waste lyes |
| abstract | A melt of sodium sulphide and carbonate is obtained by combustion, based on a reducing process, of sodium sulphite and bisulphite waste lyes and in order to oxidize the sodium sulphide to sulphate, the liquid melt is pulverized or atomized at 700 DEG -900 DEG C. after flowing out from a recovery unit, by a current of steam or steam and water at 2-15 atmospheres, the coarser particles are separated in a cyclone, ground in a pulverizing mill and fed separately or with the fine fraction, e.g. 80-90% and the atomization steam at 200 DEG -400 DEG C. to an oxidation system with cold moist air so as to maintain in the reactor a temperature of 130 DEG -250 DEG C. without further heat being fed into the reactor. The melt may be granulated on a grid at 400 DEG -600 DEG C., fed into the pulverizing mill and then fed at 200 DEG -400 DEG C. into the reactor for oxidation. The melt is produced from waste lyes, from the production of cellulose or hemicellulose by the sulphite process, which are condensed and calcined. |
