Abstract
Раскрыт способ удаления пыли карбамида из отходящего газа доводочной секции установки по производству карбамида. Способ включает гашение отходящего газа водой с получением гашеного отходящего газа. Гашеный отходящий газ увлажняют посредством смешивания указанного потока гашеного газа с увлажняющей текучей средой, выбираемой из (а) насыщенного водяного пара и (b) перегретого водяного пара, смешанного со вторым потоком воды, с получением потока увлажненного газа, и осуществляют отделение частиц из указанного потока увлажненного газа (т.е. удаление пыли) с помощью промывочной жидкости, в которой растворимы, по меньшей мере, некоторые частицы в потоке газа.
