| Abstract: | Ammonia with high purity is obtained from industrial tail gas containing ammonia and carbon dioxide by high gravity reactive precipitation.The obtained carbon dioxide is reacted with calcium chloride solution in high gravity reactor to produce ultra fine calcium carbonate.The reaction conditions affected on the separation efficiency and shape of calcium carbonate and its granularity are also studied.This spindle calcium carbonate can be used especially as filler for paper to improve its properties in paper making industry. |

| Keywords: | high gravity reactive precipitation high purity ammonia ultra fine calcium carbonate continuous process |
