Description
Urea is commonly used for preparing nitrogen fertilizer, resins, cosmetics, personal care products and water treatment products; the dataset includes the main raw and auxiliary materials, energy consumption, atmospheric pollutants and solid wastes of the production process, while infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary; since a large amount of carbon dioxide is generated during the ammonia synthesis process, the urea production unit is usually combined with the ammonia plant, and therefore all the carbon dioxide used in the urea production process is considered to be recovered from ammonia synthesis; in this dataset it is modelled as a pure substance; when modelling this substance in solution, the user is required to add a solvent of their choice in the model. the data inventory is formed by merging data from multiple sources; the production process of this product is the carbon dioxide stripping process, including synthesis, decomposition, concentration, granulation, recovery, condensate treatment and other process steps.
Activity Description
The production process of this product is carbon dioxide stripping method, including synthesis, decomposition, concentration, granulation, recovery, condensate treatment and other processes.
Process Description
Urea (chemical formula CO(NH2)2) is an organic compound, CAS number: 000057-13-6. Under normal conditions of temperature and pressure, it is solid and in crystalline form. In this dataset it is modeled as a pure substance, when modeling the substance in solution the user needs to add a solvent of their choice to the model.

Technology comment
The carbon dioxide stripping method is the most commonly used process in urea plants using natural gas as raw material, and its energy consumption is much lower than the traditional aqueous full recycle method.
