Description
Насто щий способ имеет целью получение серы из промышленных газов, содержащих сероводород и сернистый ангидрид или один сероводород. Обычным вл етс прием получени серы путем взаимодействи сероводорода с сернистым ангидридом и, в частности, обычным также приемом вл етс окисление части сероводорода в сернистый ангидрид в тех газах, которые не содержат этих соединений серы в количествах , соответствующих соотношению: 2 молекулы сероводорода на 1 молекулу сернистого ангидрида.The present method is intended to produce sulfur from industrial gases containing hydrogen sulphide and sulfurous anhydride or hydrogen sulphide alone. Sulfur production by reacting hydrogen sulfide with sulfurous anhydride is common and, in particular, it is also common to oxidize part of hydrogen sulfide to sulfur dioxide in gases that do not contain these sulfur compounds in amounts corresponding to the following ratio: 2 molecules of hydrogen sulfide per 1 molecule sulfurous anhydride.
Известно применение катализационной среды дл ведени процессаThe use of a catalytic medium for the process is known.
ZHaS -f SOa - ZHaO + 3SZHaS -f SOa - ZHaO + 3S
и, в частности, применение в качестве такой среды раствора серной кислоты .and, in particular, the use of sulfuric acid solution as such medium.
Новый способ состоит в том, что серную кислоту берут концентрированную и процесс ведут при температурах серной кислоты 60-80°.A new method is that sulfuric acid is taken concentrated and the process is carried out at temperatures of sulfuric acid 60-80 °.
Новый способ в особенности пригоден дл газов с повышенной концентрацией H2S, как например, дл газов, отход щих при производстве ВаСЬ или BaSOi, технологический процесс произ (154)The new method is particularly suitable for gases with a high concentration of H2S, such as, for example, gases that are produced during the production of Bacillus or BaSOi, the production process (154)

или же из горючих газов, из которых сероводород выделен посредством химических реагентов, например, по методу „Sibord processor from combustible gases, from which hydrogen sulphide is isolated by chemical reagents, for example, by the method of “Sibord process

Наконец, указанна реакци приобретает еще значение дл р да процессов, где сразу получаетс система H2S и SO-2, например , при восстановлении SOz вод ным или генераторным газом или активированным (древесным) углем (по методу проф. Юшкевича и Коржавина) или из колчедана при окислении его вод ным паром и т. д.Finally, this reaction becomes important for a number of processes where the H2S and SO-2 system is immediately obtained, for example, when SOz is reduced with water or generator gas or activated (wood) carbon (according to the method of Prof. Yushkevich and Korzhavin) or from pyrite oxidation with water vapor, etc.
