How to stably remove S from NH3 in industry? Obtain products with stable quality
It seems the original poster didn’t clarify the question clearly; the liquid ammonia produced by ammonia synthesis plants is sulfur-free. I’m not sure what point the poster is trying to make
Is the poster referring to the desulfurization method for raw gas?
Our factory also uses NH3, but we have never heard of sulfur testing being part of the incoming material inspection. I’m not sure what type of sulfide the original poster is referring to Since it has mixed in, it must be a gas, right? Sulfur dioxide? :o
The liquid ammonia in our factory has turned red; it’s difficult to sell it. What should we do? Friendly reply earns +2 wealth. Last edited by reesl00 on 2009-3-31 08:18.]
It’s strange – at which stage did the S get mixed into your NH3? Briefly describe your production process; everyone can analyze it and remove sulfur at the source, rather than waiting until the final stage to carry out desulfurization
During the reproduction process of liquid ammonia, there is no sulfur present; if sulfur is present, the synthesis catalyst will become poisoned immediately, so how can ammonia still be produced? Wasn’t it clear enough?
Liquid ammonia should be free of sulfur; the raw gas has had all its sulfur removed before entering the synthesis process.
Don’t NH3 and S react? That would be troublesome. Where can I find such a product?
