Abstract

Получают конверсионный исходный газ, содержащий первую часть обогащенного SOдесорбированного газа. Конверсионный газ, содержащий SOи остаточный SO, образуют пропусканием конверсионного исходного газа через множество последовательно размещенных каталитических слоев, причем множество включает, по меньшей мере, 2 и не более 4 каталитических слоев. Вторую часть обогащенного SOгаза вводят, по меньшей мере, в один каталитический слой, размещенный ниже по потоку относительно вышележащего каталитического слоя в указанном множестве слоев, для повышения концентрации SOв газе, подаваемом в слой, расположенный ниже по потоку. Настоящее изобретение относится также к способу получения серной кислоты и/или олеума из источника газа, содержащего SO. Конверсионный газ, содержащий SOи остаточный SO, образуют пропусканием обогащенного SOдесорбированного газа через множество последовательно размещенных каталитических слоев. Конверсионный газ объединяют с водяным паром с образованием кислотного газового продукта, содержащего: (а) серную кислоту, образованную реакцией в газовой фазе между SOиз конверсионного газа и водяным паром, вследствие чего генерируется теплота образования серной кислоты в газовой фазе; (b) SOи (с) SO. Тепловую энергию из теплоты образования серной кислоты в газовой фазе извлекают переносом теплоты от кислотного газового продукта в водяной пар или питающую воду в непрямом теплообменнике. Затем охлажденный кислотный газовый продукт контактируют с жидкой серной кислотой в зоне абсорбции SOс образованием дополнительного количества серной кислоты и/или олеума и обедненного SOгаза, содержащего SO.Международная заявка была опубликована вместе с Get conversion source gas containing the first part of the enriched SO desorbed gas. Conversion gas containing SO and residual SO is formed by passing a conversion source gas through a plurality of catalytic beds arranged in series, the manifold comprising at least 2 and no more than 4 catalytic beds. The second part of the enriched SOgas is introduced into at least one catalytic layer located downstream of the overlying catalytic layer in said plurality of layers to increase the concentration of SO in the gas fed to the layer located downstream. The present invention also relates to a method for producing sulfuric acid and / or oleum from a source of gas containing SO. Conversion gas containing SO and residual SO is formed by passing the enriched SO to the desorbed gas through a plurality of sequentially placed catalytic beds. Conversion gas is combined with steam to form an acidic gas product containing: (a) sulfuric acid formed by the reaction in the gas phase between SO of the conversion gas and water vapor, thereby generating the heat of formation of sulfuric acid in the gas phase; (b) SO and (c) SO. Heat energy from the heat of formation of sulfuric acid in the gas phase is extracted by transferring heat from the acid gas product to water vapor or feed water in an indirect heat exchanger. The cooled acid gas product is then contacted with liquid sulfuric acid in the SO absorption zone to form an additional amount of sulfuric acid and / or oleum and depleted SO gas containing SO.
