Abstract

Procedeu de îndepartare a gazelor acide si a amoniacului dintr-o solutie apoasa care cuprinde supunerea solutiei apoase diluate unei duble distilari, întîi a amoniacului liber si apoi a celui fixat, prin trecerea unui curent de vapori, de la cea de a doua distilare precum si a efluentului apos de la prima distilare, printr-o zina de schimb indirect de caldura, pentru condensare partiala si încalzirea lichidului din prima coloana, iar în scopul reducerii gradului de corozivitate a curentului de vapori din prima distilare, mai înainte ca aceasta sa fie supus condensarii în vederea concentrarii sale în amoniac, i se mai adauga amoniac din curentul de vapori provenit de la cea de-a doua operatie de distilare.
