How to calculate the amount of ammonia and water to be used based on the ammonia-to-carbon ratio and water-to-carbon ratio (aqueous solution method)
Thread Content
I have a question for fellow sea engineers: how can one calculate the amount of ammonia and water to be added based on N/C and H/C, rather than relying on experience and the temperature changes at the top and bottom of the tower? If the CO2 flow rate is 14,000 NM3/H and the ammonia-to-carbon ratio is maintained at 3.8, how should the amount of ammonia to be added be calculated? The water-to-carbon ratio is maintained at 0.4; the No. 1 pump has a capacity of 25 cubic meters per hour and can operate with variable frequency speed control.

The data you provided is not comprehensive enough to accurately calculate the amount of ammonia and water to be added. However, in actual production, here is an estimation method for you: for each ton of ammonia, 400 Nm3 of CO2 is required. The flow rate for liquid ammonia pumps should be adjusted to around 2 m3 per ton of urea (for aqueous solutions), while the flow rate for ammonium pumps should be adjusted to around 1.1 m3 per ton of urea (for aqueous solutions). This empirical data is for reference only. This post was last edited by ymtuegj12 on 2009-2-19 08:03.]
