Experimental apparatus for measuring gas-liquid equilibrium data

Experimental apparatus for measuring gas-liquid equilibrium dataMain functions:

This device is a specialized teaching equipment for laboratory chemical engineering. The main body of the device is a small equilibrium kettle with gas-liquid double equilibrium. Its advantages include easy operation, short equilibrium time, low sample consumption, accurate measurement data, no liquid droplets carried by the vapor, and no backmixing or boiling of the liquid. It is an ideal experimental instrument. It is suitable for scientific research data determination under normal pressure.

Experimental apparatus for measuring gas-liquid equilibrium dataDevice Introduction:

Gas liquid equilibrium data is extremely important for distillation, absorption, and other processes in chemical unit operations. In the design of distillation columns, it is the most fundamental data, and many special binary systems often lack such data, which brings difficulties to the design. Accurate data can be obtained through self measurement. Therefore, it is meaningful to master the method for determining the vapor-liquid equilibrium data of simple binary solutions.
