A SINGLE STEP REMOVAL OF HYDROGEN SULFIDE FROM GASES
The present invention is directed to methods of removing H2S from a H2S containing gas by reacting H2S with a solid oxidant directly without the need of introducing a gas oxidant into the reaction. When H2S is reacted with the solid oxidant, H2S is oxidized into element sulfur and/or sulfur dioxide,...

| Zusammenfassung: | The present invention is directed to methods of removing H2S from a H2S containing gas by reacting H2S with a solid oxidant directly without the need of introducing a gas oxidant into the reaction. When H2S is reacted with the solid oxidant, H2S is oxidized into element sulfur and/or sulfur dioxide, both of which can be easily purified and separated from a post reaction gas substantially free of H2S. Therefore, the invented methods provided by the present invention offer significant advantages in removing H2S from H2S containing gases as well as recovering element sulfur and/or sulfur dioxide from H2S.
L'invention concerne des procédés permettant d'éliminer H2S d'un gaz contenant H2S par mise en réaction directe de H2S avec un oxydant solide sans introduire d'oxydant gazeux dans cette réaction. Lorsqu'il réagit avec l'oxydant solide, H2S est oxydé en soufre élémentaire et/ou dioxyde de soufre, tous deux pouvant être facilement purifiés et séparés d'un gaz de post-réaction sensiblement exempt de H2S. Les procédés de l'invention offrent des avantages significatifs du fait qu'ils permettent d'éliminer H2S des gaz contenant H2S et de récupérer du soufre élémentaire et/ou dioxyde de soufre à partir de H2S. |
