Release time：2024-06-15 23:30viewed：times
Device functions:
1. This device for measuring the gas-liquid mass transfer coefficient with a dual-drive agitator can be used to measure the gas-liquid mass transfer coefficient of different material systems. The movement speed of the gas phase and the liquid phase can be controlled separately in the stirring tank, and it can be used in a relatively wide range. The gas-liquid mass transfer coefficient was studied and determined within the velocity range.
2. Study the mass transfer mechanism and determine the m*n aspects of mass transfer resistance, which can provide a basis for strengthening gas-liquid mass transfer equipment.
