What is the significance of setting up fine desulfurization? Under what circumstances must refined desulfurization be set up?
Fine desulfurization is to remove the total sulfur (organic sulfur and inorganic sulfur) in the raw gas to less than 0.1 mg/m3. In order to protect the efficient catalysts and adsorbents in downstream processes, improve product quality, and avoid equipment corrosion and environmental pollution, fine desulfurization of the raw gas is of great significance. For downstream processes that require the total sulfur (organic sulfur and inorganic sulfur) in the raw gas to be removed to less than 0.1 mg/m3, fine desulfurization must be set up.
It is just a backup device and will not be used in most cases. Unless there is an abnormality in the system, the gas will be allowed to enter the fine desulfurization equipment.
①It can make the total sulfur content in the purified gas less than 0.1mg/m3. ② It can extend the service life of the synthesis catalyst. ③Improve the overall production level of ammonia and hydrazine. ④It is beneficial to the application of double methylmethacrylate technology in the production of synthetic ammonia and the improvement of product quality.
It mainly depends on the hydrogen quality requirements of downstream processes.
It mainly depends on the requirements of the downstream process for sulfide in the gas. If the rough desulfurization fails to meet the requirements, fine desulfurization should be set up. Fine desulfurization includes the removal of inorganic sulfur and organic sulfur.
What you said on the second floor makes sense. I want to be friends with you. How old is QQ?
