Abstract

Изобретение относится к способу извлечения пыли мочевины и аммиака из газового потока взаимодействием упомянутого газового потока с водным раствором серной кислоты, при этом образуя кислый раствор сульфата аммония и мочевины, отличающемуся тем, что кислый раствор концентрируется до расплава, содержащего менее 5 мас.% воды, такой расплав впоследствии превращается в твердые частицы, содержащие мочевину и сульфат аммония.
