Abstract

Procedimento per la rimozione e il recupero dell'ammoniaca dagli scarichi liquidi, caratterizzato essenzialmente dalle seguenti operazioni:- far reagire lo scarico liquido con anidride carbonica pura, o con un miscuglio gassoso ricco in anidride carbonica, o con almeno un carbonato, per dare carbonato di ammonio; - far reagire il carbonato di ammonio risultante con cloruro di calcio per dare carbonato di calcio e cloruro di ammonio;- sottoporre a decomposizione termica il carbonato di calcio risultante per dare ossido di calcio e
