摘要：

Gas holdup was studied in a bubble column operated at elevated temperatures for the system air-water, air-alcohol, and air-5% NaCl solution. The influence of temperature on the gas holdup was studied focally nearing the boiling points. The bubble column is 100 mm in diameter and 1.05 in height, and the gas distributor has a single nozzle that is 10 mm in diameter. The gas and liquid flowed upward concurrently through the column. The gas and liquid superficial velocities were 1-16 and 0.7 cm&middots-1, respectively. The temperature range was 25-96.56°C. A gas holdup correlation implicating the effect of the operating temperature was developed with an average deviation of 3.1%. The result of this paper can be used for the scale-up and the design of bubble columns.
