Discussion on HCN treatment issues in the purification section?
Thread Content
As the title suggests, what impact does HCN in the transformed gas entering the purification device have on that device? Does it need to be recycled separately?
HCN is toxic; its impact on the equipment is unknown, so removal could be considered!
The amount of HCN produced during gasification is very low; part of it is converted into hydrogen sulfide, while the remaining amount is removed in the pre-treatment stage of low-temperature methanol washing
How is it converted into hydrogen sulfide during the transformation? What is the reaction equation?
It definitely cannot be converted into hydrogen sulfide! It can be converted into ammonia and methane from hydrogen; according to Lianxin, the conversion rate is over 99%
Thank you, teacher, for pointing that out. I went back and looked up more information; I had misremembered it. I really did lead students astray :L
It would be great if you could upload the information you’ve found; thank you!
