Description
pa 12 С при степени очистки газа 90%. В растаор ввод т 0,5 г/л 5 , что сооюетствует содержанию серной кислоты в растворе, получаемом при водной абсорбции 5 из реальных газов. Полученный раствор пропускают через колонку диаметром 20 мм, сЬдержашую слой анионита ЭДЭ-10П в ОН-форме высотой 25 О ( 2О г сухой смолы ). До проскока серной кислоты, определ емого с чувствительностью О,01 г/л, пропускают 2О л раствора. Очищенный раствор содержит 6 r/nSOt Из очищенного от серной кислоты рас твора провод т десорбцию 5Qi путем кип чени в колбе с обратным холодильником После 30 мин кип чени удал етс 95% 5Qt, содержащегос в растворе. После десорбции раствор, содержащий О,3 г/л .ЬС ,05 г/л серной кислоты,направл ют на стадию абсорбции. Регенерацию анионита провод т 5%ным раствором аммиака со скоростью 54 5 мл/мин. В результате получают ЮОмл раствора, содержащего 140 г/л сернокислого аммони . Предмет изобретени 1,Способ очистки газов от сернистого ангидрида путем абсорбции водой и последующей регенерации насьцценного раствора поглотител десорбцией при нагревании, отличающийс тем, что, с целью повышени емкости поглотител и понижени его коррозионной активности в циклиV зеком процессе, насьп енный водный раствор сернистого ангидрида пропускают через слой средне-или слабоосновногч анионита в ОН - форме. 2.Способ по п. 1, о т л и ч а ю щ ии с тем, что, с целью утилизации серной кислоты, насыщенный последней аниошгг регенерируют водным расттором основани , например аммиаком.pa 12 C at a gas purification degree of 90%. 0.5 g / l 5 is injected into the solution, which results in the content of sulfuric acid in the solution obtained by water absorption of 5 from real gases. The resulting solution is passed through a column with a diameter of 20 mm, a holding layer of anion exchanger EDE-10P in OH form with a height of 25 O (2O g dry resin). Before the breakthrough of sulfuric acid, determined with a sensitivity of 0.01 g / l, let the 2O l of solution pass. The purified solution contains 6 r / nSOt. The 5Qi is desorbed from the solution purified from sulfuric acid by boiling in a flask under reflux. After 30 minutes of boiling, 95% of the 5Qt contained in the solution is removed. After desorption, a solution containing O, 3 g / l.LС, 05 g / l of sulfuric acid is sent to the absorption stage. The regeneration of the anion exchanger is carried out with a 5% ammonia solution at a rate of 54 5 ml / min. The result is a 100 ml solution containing 140 g / l of ammonium sulfate. The subject matter of the invention is 1, a method for purifying gases from sulfuric anhydride by absorption by water and subsequent regeneration of the ultimate solution of the absorber by desorption when heated, characterized in that, in order to increase the capacity of the absorber and reduce its corrosivity in a cyclic process, the aqueous solution of sulfuric anhydride is passed through through a layer of medium or weakly basic anion exchange resin in OH - form. 2. A method according to claim 1, in which, for the purpose of utilization of sulfuric acid, the latter is saturated with anionic and is regenerated with an aqueous base raster, for example ammonia.
