Claims (1)
- Способ удаления соединений серы из отходящих газов включает стадии контактирования отходящих газов с водным раствором, в котором растворены соединения серы; регулирования концентрации буферных соединений, таких, как карбонат и/или бикарбонат и/или фосфат в водном растворе в области значений между 20 и 2000 мэк/л; воздействия на водный раствор, содержащий сульфид, сульфидоокисляющими бактериями в присутствии кислорода в реакторе, в котором сульфид окисляют до элементарной серы; отделения элементарной серы от водного раствора и рециклирования водного раствора на стадию контактирования отходящих газов с водным раствором. Способ пригоден для удаления H2S из биогазов, вентиляционного воздуха и т. д. Он может быть использован для удаления серы из газов сгорания при введении дополнительной стадии после первой стадии и перед третьей стадией воздействием на водный раствор, содержащий соединения серы, для восстановления соединений серы до сульфида. Удаление H2S и SO2 далее повышается при остаточном содержании серы в промывной жидкости 1 - 50 г/л.
