Description
Известны способы извлечени сернистого ангидрида из промышленных газов путем абсорбции с применением различных абаорбентов, с последующей отгонкой сернистого газа путем нагревани полученного раствора. В частности, в ксилидиновои методе примен ютс сложные улавливающие устройства, при использовании глиноземного способа получают большое количество отбросов гипса.Methods are known for recovering sulfur dioxide from industrial gases by absorption using various aberbents, followed by distilling off sulfur dioxide by heating the resulting solution. In particular, complex catcher devices are used in the xylidine method, using a large amount of gypsum waste using the alumina method.
С целью устранени указанных недостатков предложен способ извлечени сернистого ангидрида из промышленных газов, по которому в качестве абсорбента примен в раствор основного сульфата хрома - С t- (ОН)5 0 с основностью 35-50}5. Дл пополнени потерь абсорбента при его регенерации в абсорбент ввод т хромихромат ( приготовлени раствора абсорбента к хромихромату добавл ют серную кислоту в количестве , необходимом дл получени основности раствора равной 35-50.In order to eliminate these drawbacks, a method has been proposed for the recovery of sulfur dioxide from industrial gases, in which C as the absorbent is used in a solution of basic chromium sulfate - C t- (OH) 5 0 with a basicity of 35-50} 5. In order to replenish the losses of the absorbent during its regeneration, chromochromate is introduced into the absorbent (preparation of the absorbent solution is added to the chromichromate sulfuric acid in an amount necessary to obtain a basicity of the solution equal to 35-50.
Образовавшуюс жидкую пульпу обрабатывают сернистым ангидридом. При этом хромихромат восстанавливаетс и переходит в раствор в виде основногоThe resulting liquid slurry is treated with sulfuric anhydride. In this case, the chromium chromate is reduced and goes into solution as the main
сульфата хрома. Зуммарное уравнение реакции (дл раствора основностью 5У) ™2 °4 - 3502 1001 (ОН)5 0 + aUgO. Через указанный раствор пропускают промышленные газы, после чего раствор, содержащий 60, регенерируют путем нагревани и добавл ют хроийхройат дл пополнени потерь основного сульфата хрома.chromium sulfate. The buzzer reaction equation (for a solution of basicity 5U) ™ 2 ° 4 - 3502 1001 (OH) 5 0 + aUgO. Industrial gases are passed through this solution, after which the solution containing 60 is regenerated by heating and chromium chloride is added to replenish the loss of basic chromium sulfate.
