Regarding the production of liquid oxygen
Thread Content
Hello everyone. The air separation equipment in our plant is not able to produce the desired output. Its design capacity is 5300 Nm3/h, but currently we can only achieve around 2300 Nm3/h in terms of ammonia production. Additionally, we are also producing liquid oxygen, but only 400 kg per hour – which I think is far from sufficient. I’m not sure why this is happening, so I would like to ask those who are more experienced in this field: Since the plant was originally designed for gas production, could the issue with the low volume of liquid produced be related to the design itself, or is it a problem with our operating procedures? Please give me some advice, guys
Oh, right, I forgot to mention something. Our current load is almost at its limit; the total volume of air entering is 28,000 m3. Assuming an oxygen content of 20%, that means there’s 5,600 m3 of oxygen available. Yet only 2,300 m3 of it was used – so why is only 400 kg of liquid oxygen produced? ! ! !
