Description
Изобретение относитс к способам очистки газов от серннстых соединений, иреимущественно от окислов серы, адсорбцией Мп-содержащими соединени ми.The invention relates to methods for the purification of gases from sulfur compounds, and mainly from sulfur oxides, by adsorption of Mn-containing compounds.
Известен способ очистки газов от окислов серы путем контактировани очищаемых газов с твердым сорбентом -- брикетами, содержащими окислы или карбонаты марганца с добавкой железосодержащих отходов.A known method of cleaning gases from sulfur oxides by contacting the gases to be purified with a solid sorbent is briquettes containing oxides or carbonates of manganese with the addition of iron-containing waste.
Предложенный снособ отличаетс от известного тем, что в качестве Мп-содержащего сорбента используют активированную и гидратированную окись марганца, что позвол ет увеличить степень очистки газа от окислов серы до 85% против 8% по известному способу. Способ заключаетс в адсорбции окислов серы из очищаемого газа при контактировании последнего с твердым сорбентом - активной водной окисью марганца. Очищенные газы через пылеуловитель выбрасывают в атмосферу , а адсорбент обрабатывают водой или водным раствором сульфата аммони дл выщелачивани сульфата марганца, что обеснечивает отделение непрореагнровавшего адсорбента , который вновь используют дл очистки газа. Водный раствор сульфата марганца обрабатывают в колонне аммиачной водой и кислородом дл получени смеси гидроокнги марганца и низших окислов с последующим окпслением ее до водных активных окислов марганца.The proposed removal method differs from that known in that activated and hydrated manganese oxide is used as the Mn-containing sorbent, which allows increasing the degree of gas purification from sulfur oxides to 85% versus 8% by a known method. The method consists in adsorbing sulfur oxides from the gas to be purified upon contacting the latter with a solid sorbent — active aqueous manganese oxide. The purified gases are discharged to the atmosphere through a dust collector, and the adsorbent is treated with water or an aqueous solution of ammonium sulfate to leach the manganese sulfate, which removes the unreformed adsorbent, which is again used to clean the gas. An aqueous solution of manganese sulphate is treated in the column with ammonia water and oxygen to produce a mixture of manganese hydroxides and lower oxides, followed by oxidation to aqueous active manganese oxides.
Пример осуществлени способа. Очистку газа осуществл ют в адсорбционном аппарате неподвижного типа или в газоочистительной установке воздущного переносного типа, заполненных актпвнрованной окисью марганца, котора адсорбирует окислы серы из очищаемого газа, пропускаемогоAn example of the method. Gas purification is carried out in a fixed-type adsorption apparatus or in a portable-type air-cleaning gas purification unit filled with actinized manganese oxide, which adsorbs sulfur oxides from the gas to be passed through.

Адсорбент по мере насыщени окислами серы регенерируют выщелачиванием водным раствором сульфата аммони или водой. Получеиный раствор сульфата марганца (1,4 моль/л подают в двухступенчатую окисл ющую з таповку непрерывного действи , в которой его обрабатывают аммиачной водой (5.6 моль/л) кислородом (90-95% чистоты ), пропускаемым со скоростью 450- 500 л/час, дл получени смеси гидроокиси марганца и низких окислов с последующим окислением ее до водной активной окиси марганца . Полученна окись марганца имеет со3 0,337 ejCM, площадь поверхности 130 . качестве побочного продукта получают сульфат аммони (35 вес. %) высокой степеки чистоты, который далее возвращают в процесс на стадию выщелачивани . j-j редмет изооретени Способ очистки газов от окислов серы путем контактировани очищаемых газов с твер4 дым Мп-содержащим сорбептом с последующей регенерацией его выщелачиванием, отличающийс тем, что, с и.елыо иовышени степени очистки, в качестве Мп-содержащего сорбента примен ют активированную и гидратированную окись марганца, а выщелачивание осуществл ют водным раствором сульфата аммони , The adsorbent, as it is saturated with sulfur oxides, is regenerated by leaching with an aqueous solution of ammonium sulfate or water. The resulting solution of manganese sulphate (1.4 mol / l is fed to a two-stage oxidizing continuous sintering, in which it is treated with ammonia water (5.6 mol / l) with oxygen (90-95% purity) passed at a speed of 450-500 L / hour, to obtain a mixture of manganese hydroxide and low oxides, followed by its oxidation to an aqueous active manganese oxide. The resulting manganese oxide has a content of 0.337 ejCM, surface area 130.
