鼓泡塔中气含率的研究

Study on Gas Hold-up in Bubble Column

在φ100×5mm的鼓泡塔中,用空气-稀醇溶液和空气-稀酸溶液研究了包括分子中碳原子数和羟基、羧基在内的诸因素对气含率的影响。得到了气含率ε_G关联式,用于单元醇(或酸)、多元醇(或酸)的气含率计算。

The effects of various factors, including the number of carbon atoms, hydroxyl and carboxyl radicals in a molecule, on gas hold-up have been studied in a bubble column of 100×5mm in diameter, using air-dilute alcohol solutions and air-dilute aliphatic carboxylic acid solutions. Correlations of gas hold-up ε_Ghave been obtained, which can be used to estimate the gas hold-up in the solutions of monobasic alcohols (or carboxylic acids), polyhydric alcohols and polybasic acids.
