Abstract

Abstract:

Urea phosphate as a kind of water soluble compound fertilizer containing nitrogen and phosphorus has advantages of high concentration and high efficiency.Based on the advantages of low energy consumption,low environmental pollution and low cost in the production of wet-process phosphoric acid,the preparation of urea phosphate by wet-process phosphoric acid has been widely concerned by Chinese scholars in recent years.The properties of urea phosphate,agriculture industry standard and national standard,preparation principle and method and the research progress on preparation of urea phosphate with the wet-process phosphoric acid in recent years were summarized.The future development direction of urea phosphate preparation was forecasted.Further study on mass transfer phenomenon and theory of the impurity ions in the processes of urea phosphate preparation and crystallization as the fundamental for realization and optimization of the urea phosphate preparation with wet-process phosphoric acid was pointed out.

Key words: wet-process phosphoric acid, urea phosphate, phosphate fertilizer
