Abstract

An online multiphase measuring method of concentration and diameter distribution of dispersed phase particles in a multiphase reactor is provided in the present invention. The method is based on an online multiphase measuring instrument. The method described herein includes the following steps: (1) the online multiphase measuring instrument is placed in a multiphase system, and an image of the particles in the multiphase system is obtained; (2) valid particles are determined as: the particle that its Grad(Φ) is greater than or equal to Grad(Φ) is labeled as a valid one; (3) the particle diameter is calculated by d=10×n/N; according to the equation the concentration of the valid particles is calculated. The concentration and diameter of bubbles, droplets or solid particles can be obtained in real time and online measurement. The accuracy of this method is high.
