The oxygen-enriched gas from the nitrogen station is used for sulfur recovery
Thread Content
The oxygen-rich gas emitted from the nitrogen plant has an oxygen content of over 30%; can it be used in sulfur recovery units to react with acidic gases in order to increase the temperature at the furnace outlet and boost sulfur production? Are there any application examples, and what are the results?
Absolutely. The use of oxygen-enriched processes for sulfur recovery has seen rapid development in recent years. Its advantage is that it allows the processing load of the unit to be increased to varying degrees without the need for additional facilities, while simultaneously raising the temperature of the reaction furnace and increasing the conversion rate. Generally, when the oxygen concentration is below 28%, the original system can be switched from using air to using oxygen-rich gas without any modifications ； However, when the oxygen concentration exceeds 28%, the safety level of the pipelines and equipment must be appropriately upgraded. Therefore, I suggest that in the situation mentioned by the original poster, some air can be mixed into that oxygen-rich air to bring its concentration to 28%. Currently, in some coal chemical plants that produce sulfur from acidic gases, due to the very low H2S concentration, oxygen-enriched or even pure oxygen processes are commonly used.
Thank you for participating in the discussion. Do you have any relevant materials? Could you share some for other sea enthusiasts to use?
The sulfur processing plant where I work currently uses an oxygen-enriched process, with an oxygen concentration of around 30%. Ammonia-burning furnaces are employed there; blowers are used primarily for air supply, and oxygen enrichment is utilized to raise the furnace temperature. There is a temperature control system in place, and automation can be activated when the conditions of the acidic gases remain stable
Netherlands-based Heffong Technology has considerable experience in this area; it held two technical seminars related to the rich-enrichment process in Xi’an and Beijing a few days ago. Therefore, you can obtain relevant materials from them – you can contact Li Weiqiang at the phone number 13911772951.

We have several facilities in the U.S. That being the case, we could arrange a technical exchange. My contact number is 15902220812, and my last name is Chen
The application of oxygen enrichment in sulfur recovery involves a specific concentration of oxygen, which depends on the level of H2S in the acidic gases. When oxygen enrichment is used, the combustion temperature rises, so a comprehensive evaluation is necessary.
