Description
Известно удаление двуокиси серы из промышленных газов растворами сульфита аммони с последующнм переводом нолучениых г.родуктов в сульфат аммони и серу.The removal of sulfur dioxide from industrial gases by ammonium sulfite solutions is known, followed by the conversion of non-traded city products to ammonium sulfate and sulfur.
Дл извлечени аммиака из коксовых газов примен етс способ промывки газов растворами сернистой кислоты.To remove ammonia from coke oven gases, a method of washing the gases with sulfuric acid solutions is used.
Предлагаетс способ извлечени двуокиси серы из промышленных газов с применением раствора сульфита аммони : образуюнипгс бисульфит аммони используетс далее дл извлечени аммиака из коксовых газов. При этом бисульфит аммони вновь переходит в сульфит аммони , а последний используетс дл извлечени двуокиси серы.A method for the recovery of sulfur dioxide from industrial gases using an ammonium sulfite solution is proposed: ammonium bisulfite is used to form ammonium bisulfite further used to extract ammonia from coke oven gas. In this case, ammonium bisulfite again goes into ammonium sulfite, and the latter is used to extract sulfur dioxide.
Предлагаемый способ извлечени двуокиси серы из промышленных газов может быть осундествлен следуюш,им образом. Через скрубберы, орошаемые сульфитом аммони , пропускают снизу вверх продукты горени нарокотельных установок. Раствор сульфита аммони частично превращаетс при этом в бисульфит аммони . Сульфит-бнсульфитный раствор подаетс в скрубберы коксового газа, где бисульфит реагирует с аммиаком, ооразу вповь сульфит аммони . Раствор сульфита аммони возвращаетс на скрубберы дымовых газов и циркулирует до достижени определенной концентрации сульфитного Н1елока.The proposed method for the recovery of sulfur dioxide from industrial gases can be suitably followed by them. Through the scrubbers, irrigated with ammonium sulphite, the combustion products of the lending facilities are passed from bottom to top. The ammonium sulfite solution is partially converted into ammonium bisulfite. The sulphite-bnsulphite solution is fed to the coke oven gas scrubbers, where the bisulphite reacts with ammonia, orazu vpov ammonium sulphite. The ammonium sulphite solution is returned to the flue gas scrubbers and circulates until a certain concentration of sulphite H 1 is reached.
В скрубберах коксобензольного газа нар ду с осно:вным процессом происходит образование небольщих количеств тиосульфата за счет сероводорода , нрисутствующего в коксов-альных газах.In coke-benzene gas scrubbers, along with the main process, small amounts of thiosulfate are formed due to hydrogen sulfide, which is present in coking gases.
Растворы сульфита аммони , получающиес в результате проведени предлагаемого способа, могут быть переработар1ы в сульфат аммони одним из общеприн тых методов.The ammonium sulphite solutions resulting from the proposed process can be processed into ammonium sulphate by one of the conventional methods.

что получаемый при этом раствор бисульфита амлюпи используют дл извлечени аммиака из коксовых газов с одновремеииой регенерацией при этом раствора сульфита аммони .that the resulting solution of bisulfite amlyupi is used to extract ammonia from coke oven gases while simultaneously regenerating ammonium sulfite solution.
