Description

Изобретение относитс  к очистке отход щих газов от окислов азота и окислов серы в производстве капролактама.The invention relates to the purification of waste gases from nitrogen oxides and sulfur oxides in the production of caprolactam.

Известный способ очистки отход щих газов от окислов азота водным раствором карбо ата и бикарбоната аммони  не обеспечивает высокой степени очистки и, кроме того, невозможно очищать газы от двуокиси серы.The known method of purification of waste gases from nitrogen oxides with an aqueous solution of ammonium carbonate and ammonium bicarbonate does not provide a high degree of purification and, in addition, it is impossible to purify gases from sulfur dioxide.

С целью устранени  указаиных недостатков , предлагаетс  способ, по которому водный раствор карбоната аммони  примен ют в смеси с перекисью водорода, причем карбонат аммони  берут в количестве 5-25%, а перекись водорода - 0,5-3%.In order to eliminate the above disadvantages, a method is proposed in which an aqueous solution of ammonium carbonate is used in a mixture with hydrogen peroxide, with ammonium carbonate taken in an amount of 5-25%, and hydrogen peroxide 0.5-3%.

Способ осуществл ют следующим образом.The method is carried out as follows.

Отход щие газы, содержащие окислы азота и серы, а также аэрозоли нитрита и сульфат-сульфита аммони  направл ют в абсорбер , который орощают воднокарбонатаммонийным раствором перекиси водорода. Процесс протекает по реакци м:Exhaust gases containing oxides of nitrogen and sulfur, as well as aerosols of nitrite and ammonium sulfate sulfite are sent to the absorber, which is irrigated with ammonium carbonate ammonium hydrogen peroxide solution. The process proceeds according to the reactions:

2NO + ИгОг + (МП4)2СОз 2NO + IgOg + (MP4) 2CO3

2Nn4NO2 + СОа +-Н2О 2Nn4NO2 + COA + -H2O

SOa + НгОа + (НН4)2СОз SOa + HgOa + (HH4) 2CO3

(NH4)2S04 + С02 +-П2О (NH4) 2S04 + C02 + -P2O

Степень абсорбции возрастает до 98-99%. Получаемые растворы нитрита аммони  и сульфата аммони  могут быть направлены па дальпейщую переработку в соответствующие цеха по производству нитрита и сульфата аммони .The degree of absorption increases to 98-99%. The resulting solutions of ammonium nitrite and ammonium sulfate can be sent to the appropriate processing plant to the appropriate ammonium nitrite and ammonium sulfate production facilities.
