Изобретение относитс к способам обезвреживани газовых выбросов, содержащик метилметакрилат (ММА), и может быть использовано при получении органического стекла, а также в других производствах, примен ющих инициаторы.The invention relates to methods for the neutralization of gas emissions, containing methyl methacrylate (MMA), and can be used in the preparation of organic glass, as well as in other industries that use initiators.
Известен способ очистки воздуха от органических веществ, в том числе и мономеров, путем адсорбции на активном угле l . По этому способу улавливание органических веществ производ т активным углем. После насыщени с целью выделени адсорбционного продукта адсорбент подвергают термической регенерации (вод ным паром, воздухом, азотом и др.). По окончании регенерации адсорбент сушитс (при использовании вод ного пара) и охлаждаетс . Однако данный способ позвол ет очищать от мономеров газовые выбросы, которые не содержат инициаторов. В противном случае на адсорбенте будет происходить интенсивна полимеризаци мономера,A known method of air purification from organic substances, including monomers, by adsorption on the active angle l. In this method, the capture of organic matter is produced by active carbon. After saturation in order to release the adsorption product, the adsorbent is subjected to thermal regeneration (with water vapor, air, nitrogen, etc.). At the end of the regeneration, the adsorbent is dried (using water vapor) and cooled. However, this method allows the removal of monomers from gaseous emissions that do not contain initiators. Otherwise, the polymerization of the monomer will be intense on the adsorbent.
забивание пор полимером, что приведет к потере адсорбционных свойств угл и к замене его на свежий.plugging of the pores with polymer, which will lead to the loss of the adsorption properties of the coal and its replacement with the fresh one.
Известен также способ очистки газовых выбросов от непредельных углеводородов путем адсорбции на активном угле L2J. Недостатком способа вл етс сравнительно низкий срок службы сорбента и мала эффекЧгивность очистки воздуха от метилметакрилата, так как в процессе обезвреживани происходит полимеризаци мономера.There is also known a method of cleaning gas emissions from unsaturated hydrocarbons by adsorption on active carbon L2J. The disadvantage of this method is the relatively low service life of the sorbent and the low efficiency of air purification from methyl methacrylate, since the polymerization of the monomer takes place during the decontamination process.
Целью изобретени вл етс увеличение срока службы сорбента и возможность очистки выброснык газов от метил- метакрилата.The aim of the invention is to increase the service life of the sorbent and the ability to clean the emissions of gases from methyl methacrylate.
Поставленна цель при очистке газов от непредельных соединений активным углем достигаетс за счет того, что газ предварительно пропускают через слой пека, вл ющегос отходом производства органического стекла.The goal set for the purification of gases from unsaturated compounds with active carbon is achieved due to the fact that the gas is previously passed through a layer of pitch, which is a waste product from the production of organic glass.
Пример. Паровоздушную смесь (ПВС) с содержанием AWA ЗО мг/л иExample. The steam-air mixture (PVA) with AWA content of mg / l and
инициатора 0,04 мг/л пропускают при 30 G через две адсорбционные колонки, соединенные последовательно. В первую по хоДу газа колонку помещают пек (около 1 г), во вторую - активный уголь марки АР-3 (около 10 г). После адсорбции уголь подвергают регенерации вод ным паром при 110-120 С в течение 1 ч. Расход пара не превышает 5-6 кг/к рекуперата. После окончани регенерации уголь сушат гор чим воздухом при НО-120°С, охлаждают до 30°С и став т на вторичную адсорбцию. Скорость ПВС и воздуха при сушке составл ет 0,2 м/с.initiator 0.04 mg / l is passed at 30 G through two adsorption columns connected in series. The first in the course of the gas column is placed pitch (about 1 g), in the second - active carbon brand AP-3 (about 10 g). After adsorption, coal is subjected to regeneration with water vapor at 110–120 ° C for 1 hour. Steam consumption does not exceed 5–6 kg / k of recuperate. After termination of the regeneration, the coal is dried with hot air at HO-120 ° C, cooled to 30 ° C and placed for secondary adsorption. The PVA and air velocity during drying is 0.2 m / s.
Дл сравнени проводили опыт без пека. Результаты опытов показали, что в присутствии пека количество полимера на угле уменьшаетс более чем в 2 раза , в результате чего срок службы ад- сорбента увеличиваетс в 1,5-2 раза, что позвол ет использовать способ дл For comparison, the experiment was carried out without pitch. The results of the experiments showed that in the presence of pitch the amount of polymer on coal decreases by more than 2 times, as a result of which the service life of the adsorbent increases by 1.5–2 times, which allows using the method for
очистки газовых выбросов от паров непредельных углеводородов.cleaning gas emissions from vapors of unsaturated hydrocarbons.
