Abstract

"MéTODO DE REMOçãO DE AMÈNIA DE UM GáS QUE COMPREENDE CIANETO DE HIDROGêNIO, AMÈNIA E áGUA". A presente invenção refere-se a um método de remoção de amónia de um gás que compreende HCN, amónia e água, através do contato, em primeiro lugar, do gás com fosfato de amónio aquoso para remover amónia do gás e passagem em seguida da solução de fosfato de amónio resultante através de um eletrolisador para converter oxalatos e formatos em hidrogênio e dióxido de carbono.
