Description

Изобретение относитс  к способу очистки газов от хлористого водорода с применением ионообменных смол, который может быть применен в практике санитарной очистки отход щих газов металлургических и химических производств.The invention relates to a method for purifying gases from hydrogen chloride using ion exchange resins, which can be applied in the practice of sanitizing waste gases from metallurgical and chemical industries.

Известен способ очистки газов от хлористого водорода путем сорбции анионитами в хлоридной форме ко механизму молекул рного иоглош.енил. Однако такой способ очистки газов с применением ионитов недостаточно эффективен . Динамическа  емкость сло  сорбента сост.вл ет 10-15 вес. % дл  сильноос} овных анионитоз, при этом в элюате получают раствор сол ной кислоты с концентрацией до 3 моль/л.A known method of purifying gases from hydrogen chloride by sorption by anion exchangers in chloride form to the mechanism of molecular absorption. However, this method of cleaning gases using ion exchangers is not effective enough. The dynamic capacity of the sorbent layer is 10-15 wt. % for strongly axillary anionites, while in the eluate a solution of hydrochloric acid with a concentration of up to 3 mol / L is obtained.

С целью повыи1ени  эффективности очистки и увеличени  концентрации сол ной ки слоты в элюате десорбции, предлагаетс  сильноосновной аннонит в хлоридной форме использовать в смеси с сильнокислотным катионитом в форме металла - комплексообразовател , например кадми  цинка, железа (III). при соотношении ионогенных групп от 1 : 0.9 до 1:1,1.In order to improve the purification efficiency and increase the concentration of hydrochloric acid in the desorption eluate, it is proposed to use strongly basic annonite in chloride form in a mixture with a strongly acidic cation exchanger in the form of a complexing agent, such as cadmium zinc, iron (III). when the ratio of ionogenic groups from 1: 0.9 to 1: 1,1.

Предложенный способ позвол ет повысить динамическую емкость сорбента в сравнимых услови х в2--3 раза (до 20-30 вес. %). Кроме того, при водной регенераций отработанной смеси сильи.оосновцого анионита иThe proposed method allows to increase the dynamic capacity of the sorbent in comparable conditions by 2--3 times (up to 20-30 wt.%). In addition, when water regeneration of the spent mixture of silionic anion exchange resin and

сильнокислотного катионита получают в элюате раствор сот ной кислоты с концентрацией 4 моль/л.Strong acid cation exchanger in the eluate is prepared in the eluate of 4 mol / L.

Пример. В стекл нную колонку диаметром 20 мм помещают зквимол риую смесь сильноос::ов1 ого анюнита АВ-17 в хлоридиой форме и сильнокислотного катионита КУ-2 в -форме с фракцией 0,6-0.9 мм. Использование экви.мол рной смеси целесообразно дл  более полного 1:сиользовани  эффекта увеличени  динамической емкости смещанного сло  ио НС1.Example. A glassy column with a diameter of 20 mm is placed in a glassy mixture of strongly axed :: anyunite AB-17 in chloride form and a strongly acid cation exchanger KU-2 in α-form with a fraction of 0.6-0.9 mm. The use of an equimolar mixture is advisable for a more complete 1: use of the effect of increasing the dynamic capacity of the displaced layer of HC1.
