化学法测定磷铵管式反应器气液相界面积

Chemical method for measuring the Gas-Liquid area in Ammonium phosphate pipeline-reactor

本文论述了用化学法测定的磷铵管式反应器在不同流动状况及安装形式下的气液相界面积.实验中发现,在过渡区范围内表观液速对气液相界面积有负效应,对气液传质有不利影响;因而在实际操作过程中应避开过渡区.文中所列实验数据与文献很吻合,说明结论是可信的.

Chemical method was used to measure the Gas-Liquid(G-L)interracial area in the Ammonium phosphate pipeline reactor under different fluid conditions and fitting styles (Horizontal and Vertical).It was found that in the fluid transition region the superficial liq- uid velocity had negtive effect on the G-L interracial area,while the mass transfer would be lower,so it was recommended that in practical operation it should be avoided from the tran- sition region.The results had been shown very well comparing with the references data.
