Problem of recovering waste carbon dioxide from the synthesis workshop in the urea workshop
Thread Content
The urea production process in my workshop uses the carbon dioxide stripping method. However, there is a pipeline carrying recycled carbon dioxide from the synthesis workshop connected to the inlet pipeline of the carbon dioxide compressor. May I ask: why was this recycled pipeline added? Which section of the synthesis workshop does it originate from? What are the components present in this carbon dioxide? What impact will it have on the carbon dioxide compression unit? This question is rather superficial; I apologize to the experts for that, as I have no prior experience in compressor operations. I hope you will answer it carefully, and I will certainly reward you generously within reasonable limits! This post was last edited by lxq700918 on 2009-1-7 22:15.]
OP, the carbon dioxide produced in urea production originally comes from the decarburization process of the ammonia synthesis plant. I’m not sure whether the “polluted carbon dioxide” referred to by the original poster does not originate from the decarbonization process So, may I ask the original poster: What process do you use for producing synthetic ammonia? How can there be \"dirty carbon dioxide\"? If the original poster doesn’t provide clear details, there’s no way to discuss it!
That’s right. However, if this CO2 contains other impurity gases, it will certainly affect the stability of the device as well as the reaction conversion rate. This post was last edited by lxq700918 on 2009-1-8 at 18:08
