Изобретение может использоватьс дл извлечени сернистого ангидрида из газовых смесей с последующей его утилизацией.The invention can be used to extract sulfur dioxide from gas mixtures and then dispose of it.
Известен р д способов очистки отход щих газов от сернистого ангидрида, основанных главным образом на абсорбции сернистого ангидрида различными поглотител ми, в качестве которых используют водные растворы органических оснований (ксилидин, толуидин, хинолин , диметиламин) и оксикислоты 1.A number of methods for purifying waste gases from sulfur dioxide are known, based mainly on the absorption of sulfur dioxide by various scavengers, which use aqueous solutions of organic bases (xylidine, toluidine, quinoline, dimethylamine) and hydroxy acids 1.
Недостатками известных способов вл ютс сложность в оформлении технологического процесса и низка степень очистки газа от SOz.The disadvantages of the known methods are the complexity in the design of the process and the low degree of gas purification from SOz.
Известен способ очистки газов от сернистого ангидрида путем абсорбции последнего органическим сорбентом, в качестве которого используют диалкилпроизводные бензола и дифенилметана 2.A known method of purification of gases from sulfur dioxide by absorption of the latter with an organic sorbent, which is used as dialkyl derivatives of benzene and diphenylmethane 2.
Основной недостаток такого способа-иизка степень очистки (91-93%).The main disadvantage of this method is the degree of purification (91-93%).
С целью повышени степени очистки газа в качестве органического сорбента используют парафиновые углеводороды с числом углеродных атомо В Ci2-Ci8, например, парафин, синтин .In order to increase the degree of gas purification, paraffin hydrocarbons with the number of carbon atoms B Ci2-Ci8 are used as an organic sorbent, for example, paraffin, sintin.
Предлагаемый способ позвол ет повысить степень очистки газов от сернистого ангидрида до 99%.The proposed method allows to increase the degree of purification of gases from sulfuric anhydride to 99%.
Пример 1. Газовую смесь с концентрацией сериистого ангидрида 0,45 об. % пропускают со скоростью 160 л/час через насадочную колонку высотой 2,5 м и диаметром 30 мм. Колонку орошают синтино-м со скоростью 3-3,5 л/час при 25°С. Концентраци сернистого ангидрида в газовой с.меси после очистки 0,00075 г/л.Example 1. The gas mixture with a concentration of serum anhydride of 0.45 about. % is passed at a speed of 160 l / h through a packed column 2.5 m high and 30 mm in diameter. The column is irrigated with Sintino-m at a speed of 3-3.5 l / h at 25 ° C. The concentration of sulfurous anhydride in the gas mixture after purification is 0.00075 g / l.
Степень очистки составл ет 94,6%. Содержание сернистого ангидрида в поглотителе - 0,,6 вес. %.The degree of purification is 94.6%. The content of sulfuric anhydride in the absorber - 0,, 6 wt. %
Пример 2. Абгазы стадии сульфохлорнровани парафинов Ci2-Ci8, содержащие 75 об. % сернистого ангидрида, пропускают со скоростью 160 л/час через насадочную колонку высотой 2,5 м и диаметром 30 мм. Колонку орошают парафинами Ci2-Cis со скоростью 3-3,5 л/час при 25°С. Степень очистки составл ет 99%. Содержание сернистого ангидрида в поглотителе 0,4в вес. % Example 2. Sulfur chloro chlorination paraffins of Ci2-Ci8 paraffins containing 75 vol. % of sulfur dioxide, is passed at a speed of 160 l / h through a packed column 2.5 m high and 30 mm in diameter. The column is irrigated with Ci2-Cis paraffins at a speed of 3-3.5 l / h at 25 ° C. Purification rate is 99%. The content of sulfuric anhydride in the absorber of 0.4 V in weight. %
