Ammonia synthesis process with liquid nitrogen washing process
Thread Content
In an ammonia synthesis process that uses liquid nitrogen washing, is there no air release in the synthesis loop?
There should still be some vent gas, but less than that in the methanation purification process.
It doesn’t sound right! This title! www.donghongsheng.com Liquid nitrogen-liquid oxygen-nitrogen displacement
But we don’t allow emptying; it goes back to the previous system
Which previous section should we return to? Should it go back directly or be processed first?
There is basically none; only a portion of hydrogen and nitrogen is dissolved in liquid ammonia, and some of this ammonia-containing hydrogen and nitrogen is released when the pressure is reduced
Check whether it is an air separation unit with all components removed; if not, inert gases such as argon are still present.
