Bubble Tank를 이용한 아세트알데히드 흡수반응특성 연구
Abstract
Absorption characteristics of acetaldehyde (one of odors) were investigated using a bubble tank. The capacity of reaction tank made of acrylic is I liter and the experiment was carried out as semi-batch mode (for given absorbent packing, acetaldehyde was fed continuously with flow rate of 2 L/min). As operating variables of experiment, concentration of acetaldehyde (40~100 ppm), absorption temperature (25~45℃), and packing volume of absorbent (100~300 ㎖) were applied. The experimental results showed that the removal efficiency of acetaldehyde decreased as 20~30%, with increasing concentration of acetaldehyde in the range of 40~100 ppm, and decreased as 15~30%, with increasing absorption temperature in the range of 25~45°C, while it increased with increasing packing volume of absorbent. Reaction rate which is measured by experiment is well matched with the calculated one from theoritical rate equation.
