水吸收氨吸收塔,采用的是填料吸收塔来用水吸收氨属于中等溶解度的吸收过程,填料塔不仅结构简单,而且阻力小,便于用耐腐蚀材料制造,对于直径较小的他,处理有辐射性的物质或要求降压较小的真空蒸馏系统,填料塔都有明显的优越性.为提高传质效率,选用逆流吸收流程。工作生产中多采用逆流操作,逆流操作特点是,传质平均推动力大,传质速率快,分离效率高,吸收剂利用率高。
Water absorption of ammonia absorption tower, using a filler absorption tower to absorb ammonia absorption of water is moderate absorption of the absorption process, the packing tower not only simple structure, and resistance, easy to use corrosion-resistant materials, for smaller diameter he deal with radiation Material or vacuum distillation system requires less pressure relief, packed tower has obvious advantages.In order to improve the mass transfer efficiency, the choice of countercurrent absorption process. Counterproductive operation is often used in production. The countercurrent operation is characterized by large average mass transfer power, fast mass transfer rate, high separation efficiency and high utilization rate of absorbent.
