Abstract

"MéTODO PARA REDUZIR A CONTAMINAçãO A JUSANTE DE UM PROCESSO PARA RECUPERAR AMÈNIA". Um método, que reduz a contaminação de ferro de um sistema, que recebe amónia a partir de um processo de recuperação de amónia por uma ou mais das seguintes técnicas : a) Separar fisicamente óxido de ferro, ferro contendo partículas coloidais, e gotículas de líquido a partir da corrente gasosa ; b) Evitar que AC se deposite na tubulação por meio de eliminação de condensação, deste modo evitando a corrosão da tubulação; ou c) Instalar a tubulação e o equipamento, que não é suscetível a ataque corrosivo por AC, deste modo eliminando a fonte de contaminação de ferro.
