The urea plant currently produces urea crystals, which are processed into prills, pastilles and DEF solution.
Read MoreUrea is widely used in the agricultural sector both as a fertilizer and animal feed additive. The main function of Urea fertilizer is to provide the plants with nitrogen to promote green leafy growth and make the plants look lush. Urea also aids the photosynthesis process of plants. Since urea fertilizer can provide only nitrogen and not ...
Read MoreOct 25, 2020· The Manufacturing Process . Ammonia and carbon dioxide are the raw materials for the urea manufacturing process; usually, urea is manufactured in an ammonia plant because it yields ammonia as a product and carbon dioxide as a byproduct and this carbon dioxide can be recycled directly into the process. The chemical reactions involved in the process:

NH2CONHCONH2 + NH3 biuret This reaction is undesirable, not only because it lowers the yield of urea, but because biuret burns the leaves of plants. This means that urea which contains high ...
Read MoreUrea is a hot concentrated solution produced by the reaction of ammonia with carbon dioxide. When dissolved with water, this concentrated urea hot-melt liquid becomes an aqueous urea solution or a feedstock for the prilling or granulating process. Prilled urea is used for the technical grade urea market for industrial applications.
