Description
шись в теплообменнике, поступает в абсорбер, где происходит поглощение серного ангидрида серной кислотой. После абсорбера к оставшимс 105 55%-ного сернистого газа добавл етс 255 воздуха, осушенного в башие, орошаемой продукционной серной кислотой , из которой происходит также отдувка растворенного сернистого ангидрида перед передачей на склад. Полученные при этом 360 17%-кого сернистого газа, подогрева сь в теплообме(ннике, поступают в контактный аппарат с трем стационарными сло ми катализатора. Полученный в аппарате серный ангидрид поглошаетс серной кислотой в промежуточном абсорбере, а оставшийс 0,8- 1,0%-ный сернистый газ после подогрева в теплообменниках Поступает ;на окончательную переработку во второй контактный аппарат с двум стационарными сло ми катализатора и затем в последний абсорбер. Объем газа, выбрасываемого из последнего абсорбера, составл ет 270 , в пем содержитс околоIn the heat exchanger, it enters the absorber, where sulfuric anhydride is absorbed by sulfuric acid. After the absorber, to the remaining 105 55% sulfur dioxide is added 255 air, dried to the best, irrigated with production sulfuric acid, from which also the blowout of dissolved sulfur dioxide is taken before being transferred to the warehouse. The resulting 360 17% sulfur dioxide gas is heated in the heat exchange (these are fed into the contact apparatus with three fixed catalyst beds. The sulfuric anhydride obtained in the apparatus is absorbed by sulfuric acid in the intermediate absorber, and the remaining 0.8-1.0 % sulfur dioxide after heating in heat exchangers enters; final processing is carried out in a second contact device with two fixed catalyst beds and then in a final absorber. The volume of gas emitted from the last absorber is 270, in letters of lives about
0,02% сернистого ангидрида. Обш,а степень конверсии составл ет 99,9%.0.02% sulfurous anhydride. The conversion rate is 99.9%.
