Description
Изобретение преследует цель обеспечить полное улавливание окислов азота из хвостовых нитрозных газов азотпокислотных установок. От обычно прил ен емого поглощени нитрозных газов содовым раствором или известковым молоком предлагаемый способ отличаетс исключением расхода дефицитной соды, отсутствием громоздкого известкового хоз йства и выпуском аммиачной селитры вместо менее ценных натриевой или кальциевой . Способ заключаетс в поглощении нитрозных газов гидроокисью свинца и последующей ее регенерации . Схема процесса следующа .The invention aims to ensure the complete trapping of nitrogen oxides from the tail nitrous gases of nitric acid plants. The proposed method differs from the usually applied absorption of nitrous gases by soda solution or lime milk, with the exception of the consumption of deficient soda, the absence of cumbersome lime economy and the release of ammonium nitrate instead of less valuable sodium or calcium. The method consists in the absorption of nitrous gases by lead hydroxide and its subsequent regeneration. The process diagram is as follows.
