| titleOfInvention | Method of leaching heat-recovery boiler ash |
| abstract | FIELD: paper. n SUBSTANCE: method of cleaning ash of heat-recovery boiler of cellulose plant, used together with single-step or multi-step method of leaching ash, is characterised by that at least one calcium compound, most preferably, calcium oxide (CaO) and/or calcium hydroxide (Ca(OH) 2 ) is used as an additive on one or more leaching stages. Liquid fraction, formed during leaching, is outside main cycle of chemical extraction preferably as a substitute of commercial sodium hydroxide at bleaching line of cellulose plant, and solid fraction may be mixed with stream of black liquor or subjected to additional processing in order to separate a calcium compound for recycling. n EFFECT: as a result ash is cleaned from a significant amount of carbonate that it contains. n 7 cl, 2 dwg |
