Abstract

Oppfinnelsen angår en fremgangsmåte for oppkonsentrering av prosessvann og for av- gassrensing, hvor overopphetede avgasser an- vendes for oppkonsentrering av prosessvann, og hvor det samtidig i det samme apparat gjennomfares en rensing av avgassene veci hjelp av prosessvannet. En delstrom av de oppkonsentrerte prosessvanntyper fores ut og kan gjenanvendes.The invention relates to a process for concentrating process water and for exhaust gas purification, where superheated exhaust gases are used for concentrating process water, and at the same time a purification of the exhaust gases is carried out by means of the process water. A partial stream of the concentrated process water types is fed out and can be recycled.
