Дл предотвращени выноса аммиака из очистной системы газ необходимо подвергнуть еще дополнительной промывке водой.To prevent the removal of ammonia from the cleaning system, the gas must be subjected to additional washing with water.
Отработанные растворы аммиака и сульфата железа регенерируютс обычными способами .Used solutions of ammonia and ferrous sulfate are recovered by conventional methods.
