| Abstract: | With the unreacted gas from urea production as the carbonating gas, the continuous bubbling carbonation process is used to give ultrafine calcium carbonate, to realize its co-production in the conventional nitrogenous fertilizer industry, thereby increasing urea conversion, simplifying the urea technological process, reducing energy consumption, and also blazing a new trail for the co-production of ultrafine calcium carbonate. |

| Keywords: | ultrafine calcium carbonate urea co-production continuous bubbling carbonation process |
