Regarding the urea consumption quota
Thread Content
What should be the standard consumption rate for 400 tons of urea per day? My email is bybyyan@163.com. Can anyone help me? I don’t understand it
Urea raw materials, auxiliary materials, and energy consumption (based on tons of urea)
Serial Number | Name | Specification | Unit | Consumption Rate | Remarks
1 | Synthetic ammonia | NH3 > 99.5% | t | 0.589 |
2 | CO2 gas | CO2 ≥ 95.7% | t | 0.785 (based on 100%) |
3 | Recycled water | <32°C, △t = 6°C | m3 | 140 |
4 | Electricity | kWh | 150 |
5 | Fresh water | m3 | 30 |
6 | Steam | 1.275 MPa (absolute), 191°C | t | 1.36 |
7 | Instrument air | 0.588–0.785 MPa (absolute) | Nm3 | 8.3 |
8 | Lubricating oil | kg | 0.4 |
9 | Activated carbon desulfurizer | kg | 0.3 |
10 | Packaging bags | 50 kg/bag | Pieces | 20 |

May I ask moderator 138972950: Where is your 30 m3/h of fresh water mainly used? Is it the desalinated water from a suction cooler (in the case of an aqueous solution process)?
The consumption quota is related to the level of production technology; the question posed by the original poster is not clear
The consumption standards vary depending on the process used; please let the original poster specify which process is being employed.
A breakdown of the raw materials, auxiliary materials, and energy consumption (in terms of tons of urea) for the CO2-based urea production plant is provided for the owner’s reference. Serial Number Name Specification Unit Consumption Rate Remarks 1 Synthetic ammonia NH3>99.5% t 0.575 2 CO2 gas CO2≥95.7% t 0.745 (calculated at 100%) Centrifugal compressor 3 Circulating water <32°C, △t=6°C m3 100 4 Electricity kWh 110 5 Fresh water m3 50 For operation purposes 6 Steam 2.45MPa (absolute), 225°C t 0.98 7 Instrument air 0.588–0.785MPa (absolute) Nm3 20 8 Lubricating oil kg 0.2 9 Packaging bags 50kg/bag Packs 20
Consumption metrics for the main urea production unit (carbon dioxide stripping method)
Main urea production unit: Name, Specification, Unit, Consumption quota
Liquid ammonia, on a 100% basis: t, 0.575
CO2, on a 100% basis: t, 0.770
Cooling water, ≤32°C, Δt=10°C: t, 100
Electricity: kWh, 110
Steam, 2.5 MPa (A), 250°C: t, 1.05
Low-pressure steam (output): 0.45 MPa (A), 147°C: t, -0.198
Recovered steam condensate: t, 0.980
Packing bags: 50 kg/bag, Number, 20.5
Note: The above consumption metrics apply to the main urea production building; they do not include the section related to large particles. The consumption metrics for those large particles are based on the process specifications provided by Toyo. This post was last edited by 1025199692 on 2009-4-24 12:01]

Where does the data for floor 8 come from?
