Abstract

A method is described for recovering ammonia from a gas stream (101) and a waste water stream (115), both streams containing ammonia and acid gases, comprising adding alkali to the waste water stream (116), subjecting the thus treated stream to distillation with steam (118), withdrawing a hot ammonia-containing vapor stream from the distillation, passing said gas stream through an aqueous absorbing solution of ammonium phosphate (102), passing said hot ammonia containing vapor stream (120) through said absorbing solution to strip acid gases from said absorbing solution (104), and heating the absorbing solution to strip ammonia from said solution (106). <IMAGE>
