1830 Carbon dioxide stripping method, air volume calculation included
Thread Content
Carbon dioxide stripping method. Designed in 1830; currently produces 960 T of urea per day ； The amount of air added is 1100 m3. Analysis: oxygen content analysis after dehydrogenation, both online values are 0.7–0.9 ； 1.27. Theory before dehydrogenation ； In other words, a large amount of air is added. I would like to ask how to calculate the air volume to be added, with an air pressure of 0.3 MPa.
Calculated at 40 T per hour, the CO2 volume is 16,000 Nm3/h; that is, 16,000 X 0.9% ÷ 21% = 685 Nm3/h
