A Novel Method for Measuring Gas Residence Time in a Gas-Solid Separator
确定气固快速分离器气体停留时间的新方法

The gas residence time is an important parameter in the evaluation of gas-solid separator. However, there are few easy experimental methods to obtain the gas residence time. A novel method for measuring the gas mean residence time in gas-solid separator by using O3 decomposition was developed and studied in this work. The comparative results show that the proposed method can be easily applied to estimate the gas mean residence time in the gas-solid separator.
