Abstract

Изобретение относится к способу восстановления серы из газовых потоков с большим содержанием аммиака, необязательно содержащих сероводород, совместно с потоками кислотного газа, в которых объемное соотношение NН/НS выше 30 в расчете на суммарный поток двух газообразных потоков. Способ позволяет также превращать диоксид серы, содержащийся в промышленных выбросах, в сероводород и выделять серу вместе с двумя вышеупомянутыми газовыми потоками.The invention relates to a method for the recovery of sulfur from gas streams with a high content of ammonia, optionally containing hydrogen sulfide, together with acid gas streams, in which the volume ratio of NH / HS is above 30 per total flow of two gaseous streams. The method also makes it possible to convert sulfur dioxide contained in industrial emissions into hydrogen sulfide and release sulfur together with the two aforementioned gas streams.
