18.30 Explanation of the project
Thread Content
I’m here in the nitrogen fertilizer section to learn more. I don’t understand how the value 18.30 in the urea project is determined – what does it represent? Is there also a value like 20.40? Is it necessary to have a synthetic ammonia project alongside a urea production project? Could some experienced user help me explain this? Thank you!!!
18.30 refers to an annual production of 180,000 tons of synthetic ammonia and 300,000 tons of urea.
18. 30 is the device scale.
Synthetic ammonia is the main raw material for producing urea; 570-580 kilograms of synthetic ammonia are required per ton of urea. On a scale basis, the ratio between synthetic ammonia and urea is approximately 18 (synthetic ammonia) to 30 (urea)
Which devices are greater than 18.30? Which devices are less than 18.30? Thank you!!!
Devices larger than 18.30 are: 24.40, 36.52, 40.60, 50.80. Devices smaller than 18.30 are: 8.13
References to things like “18.30” pertain mainly to the design capacity required to match synthetic ammonia and urea in fertilizer production. As mentioned by a user above, there is the issue of urea ammonia consumption; the figure “18.30” is indeed related to ammonia consumption. However, the matching relationship between the two is generally calculated based on approximately 600 kg of ammonia per ton of urea produced (that is, about 0.6 tons of ammonia per ton of urea); in other words, 300,000 tons of urea require 180,000 tons of ammonia, and this is where the figure \"18.30\" comes from. Devices smaller than “18.30” generally include “8.13”, “12.20”, etc., while devices larger than “18.30” include “24.40”, “30.52”, “45.80”, etc.

The term “18.30” refers to an annual production of 180,000 tons of synthetic ammonia and 300,000 tons of urea; many places and enterprises refer to this project as the “2030” project. Devices smaller than “18.30” include “8.13”” ； Devices with a value greater than “18.30” include “30.52”. It is understood that Inner Mongolia Xinsheng Energy Chemical Co., Ltd. has invested nearly 1 billion yuan in building a “3052” project, which is expected to be completed and put into operation by August next year ； “50.80”. It is understood that Jinxin Chemical is building a \"50.80\" project, with an investment of over 3 billion yuan, and it is expected to come online in June 2011. According to what Shanghai You mentioned, are “36.52” and “45.80” the same as the “30.52” and “50.80” items? Why does it sound different no matter how you say it? Is there a relatively authoritative and unified term for this? I would appreciate it if fellow sailors could advise me. Thank you.
Synthetic ammonia is the main raw material for urea production; in the urea manufacturing process, 570–580 KG of synthetic ammonia are consumed per ton of urea produced. Therefore, urea production must be accompanied by ammonia synthesis plants.
“18.30” refers to an annual production capacity of 180,000 tons of synthetic ammonia and 300,000 tons of urea; the synthetic ammonia and urea production units operate together, with the ammonia produced being used internally by the synthetic ammonia plant to achieve a balanced supply of ammonia for its operations.
Synthetic ammonia directly provides the two raw materials, liquid ammonia and carbon dioxide, for the urea production process! However, in terms of the material balance of the existing process, the urea production capacity associated with an ammonia synthesis plant is primarily determined by the carbon dioxide output of that plant, whereas liquid ammonia is always in excess!
