喷射吸收制取超细碳酸钙新工艺

Process for producing superfine CaCO 3 by spraying absorption

介绍了采用一种高效、节能的传质设备——喷射塔来实现 Ｃａ（ Ｏ Ｈ ）２ 悬浊液吸收 Ｃ Ｏ ２ 的碳化反应，开发了超细碳酸钙喷射吸收新工艺；经测试，样品粒子的粒径约为 ００７ μｍ 。

This paper deals with the development of a novel process for producing superfine CaCO 3 by spraying absorption in jet column.The microscopic analysis of the product sample showed that the particles obtained are about 0 07 μm in size.
