Description
Изобретение относитс к способам очистки паровоздушных смесей от органических растворителей и может быть использовано в химической промышленности.The invention relates to methods for the purification of vapor-air mixtures from organic solvents and can be used in the chemical industry.
Цель изобретени - повышение сорб- ционной емкости и увеличение времени защитного действи сорбента.The purpose of the invention is to increase the sorption capacity and increase the time of the protective effect of the sorbent.
; Пример. В адсорбер диаметром 0,052 м и рысотой 0,41 м, выполненный из нержавеющей стали, загружают углеродный волокнистый адсорбент со степенью активации 20% ;(УВА--20) в количестве 20,1 г, плотность упаковки волокна 0,10 г/см , и активированный зерненый уголь марки УМС-6 в количестве 141 г, плотность упаковки 0,7 г/см , соотношение объемов слоев 1:1. В адсор- :бер со стороны зерненого угл подают паровоздушную смесь (ЛВС), содержаш,ую па- ;ры ацетона и толуола с концентрацией ;2,0 и 4,4 мг/л соответственно. Линейна скорость ПВС в адсорбере 0,31 м/с. Проско- iKOBbie концентрации органических веществ ;за слоем адсорбента фиксируют хромато- м рафическйм методом с помощью хроматографа типа ЛХИ-8ПД18. Насыщение адсорбента провод т до по влени за слоем концентрации, равной значению 0,5 предельно допустимой концентрации ацетона. Врем ; Example. A carbon fiber adsorbent with an activation degree of 20%; (UVA - 20) in an amount of 20.1 g, fiber packing density of 0.10 g / cm is loaded into an adsorber with a diameter of 0.052 m and a ounce of fish 0.41 m, made of stainless steel; and activated granular carbon brand UMS-6 in the amount of 141 g, packing density of 0.7 g / cm, the volume ratio of the layers 1: 1. In the adsor-: ber from the granulated carbon side, the vapor-air mixture (LHF) is fed, containing, in pairs, acetone and toluene with a concentration of 2.0 and 4.4 mg / l, respectively. The linear velocity of the PVA in the adsorber is 0.31 m / s. Prosko-iKOBbie concentration of organic substances; behind a layer of adsorbent is fixed by chromatography using a chromatograph of the type LHI-8PD18. The saturation of the adsorbent is carried out until the appearance behind the layer of a concentration equal to the value of 0.5 maximum permissible concentration of acetone. Time
защитного действи составл ет 110 мин, сорб- ционна емкость по ацетону 22 мг/см, масса поглощенного ацетона 8,1 г.protective effect is 110 minutes, the sorption capacity for acetone is 22 mg / cm, the mass of absorbed acetone is 8.1 g.
В таблице приведены данные по очистке паровоздушной смеси, содержащей пары ацетона и толуола.The table shows the data on the cleaning of steam-air mixture containing vapors of acetone and toluene.
Пропускание паровоздушной смеси через второй слой адсорбента, состо щего из зерен активированного угл , позвол ет увеличить врем защитного действи в 1,5- 2 раза, а сорбционную емкость в 1,5-2,5 раза.Passing the vapor-air mixture through the second layer of the adsorbent, consisting of grains of activated carbon, makes it possible to increase the protective action time by 1.5-2 times, and the sorption capacity by 1.5-2.5 times.
