Abstract

In order to study the calculation method of high volatile liquid mass transfer rate, a rectangular air duct is established, the different wind speed air flows are formed in the air passage, and the gas-liquid mass transfer loss on ether with 103.9 mm liquid surface diameter is studied experimentally, and the influences of different temperatures on the gas fluid transfer rate are analyzed. Based on the experimental results, the dimensional analysis below the boiling point temperature proposed by Donald Mackay［12］ is carried out by using Maxwell's rate distribution theory and the gas-liquid mass transfer rate calculation model, and a new temperature correction term is proposed to correct the calculation model. The experimental results of liquid level show that the gas-liquid mass transfer rate decreases with the decrease in temperature and wind speed. The value of temperature correction term coefficient is 0.559 in comparison with the calculated value. The gas-liquid mass transfer rate is proportional to the powers of 0.78 of temperature and wind speed. A gas-liquid-liquid mass transfer heat transfer experiment was carried out to make the different diameter ether liquid columns pass through a 2.0 m/s air flow, and the measurement experiment was carried out. The temperature changes of liquid before and after experiment were measured. According to the modified gas-liquid mass transfer rate calculation model, the temperature change caused by gas-liquid mass transfer energy transfer during the liquid column down-flow process is calculated and compared with the experimental results. The experimental results of liquid column downflow show that the error between the calculated and experimental results is less than or equal to 3.81%, and the calculated error of the modified gas-liquid mass transfer rate calculation model is small with high computational accuracy.Key
