What diameter should the granulation tower have for 700,000 tons of urea?
You can refer to a certain project’s urea plant with a capacity of 2,700 tons per day; the diameter of its granulation tower is 26 meters.
Now, many urea plants with a capacity of 520,000 tons per year and granulation towers with a diameter of 20 meters have, after undergoing capacity expansion, reached an output of 2,200 tons of urea per day (i.e., 700,000 tons per year), and the problem of sticky towers is not severe either； For 700,000 tons per year of urea production, a granulation tower with a diameter of 22–23 meters is sufficient (without considering capacity expansion) ； At the same time, comprehensive factors such as the selection of the granulator, the desired size of the urea product particles, and the height-to-diameter ratio of the granulation tower should also be taken into consideration.

If the annual production period is considered to be 300 days, the daily output is 2,333.3 tons. Referring to page 220 of the \"Fertilizer Engineering Series – Urea\", a length of 24 meters is sufficient.
