| Abstract: | Unreacted gas from the urea production process is used as a carbonizing gas to co produce superfine calcium carbonate by continuous bubbling carbonation.Thus,production of traditional nitrogen fertilizer can be combined with modern nanometer technology.It has a broad prospect in improvement of urea conversion,simplification of production process reduction of capacity consumption and co production of high additional value superfine calcium carbonate. |

| Keywords: | superfine calcium carbonate urea synthesis co production unreacted gas |
