Sulfur recovery ratio adjustment
Thread Content
The ratio of hydrogen sulfide to sulfur dioxide in our unit is analyzed online; after the secondary reactor, it is necessary to continuously adjust the air supply volume. Is there any process where the air supply volume does not need to be adjusted so frequently?
Production of sulfuric acid: victory::)
Automatic adjustment, without increasing your workload.
What model of ratio analyzer are you using?
I recommend the ratio meter from the Research Institute of Nanhua Group – the domestic model 880; I wouldn’t recommend it to just anyone!
Increase the flow rate of the main air, and keep the flow rate of the fine-tuning air within 800 standard liters, with minimal fluctuations.
An unreasonable ratio between the sizes of the main and auxiliary control valves, along with an acid gas volume that exceeds the design value and experiences large fluctuations, can lead to the situation where a 2:1 ratio cannot be automatically adjusted.
Reply to 6# myw: Yes, if the fine-tuning air flow rate increases, it is necessary to increase the main air flow rate appropriately, so that the range of the fine-tuning air flow rate does not fluctuate too much
