Bubble Tank를 이용한 아세트알데히드의 흡수반응특성 연구

A Study on the Absorption Characteristic of Acetaldehyde Using Bubble Tank

Absorption characteristics of acetaldehyde(one of odors) were investigated using a bubble tank. The capacity of reaction tank made of acrylic is 1 liter and the experiment was carried out as semi-batch mode(for given absorbent packing, acetaldehyde was fed continuously with flow rate of 2liter/min). As operating variables of experiment, concentration of acetaldehyde(40~100ppm), absorption temperature(25~45℃), and packing volume of absorbent(100~300ml) were applied. The experimental results showed that the removal efficiency of acetaldehyde decreased with increasing concentration of acetaldehyde and absorption temperature, while it increased with increasing packing volume of absorbent.
