Abstract
Air pollution has a huge impact on human life. Coal is the main fuel consumption that contaminates the northern cities of China and currently it cannot be completely substituted. Thus, smoke prevention and dust control measurements must be strengthened. Chemical absorption methods, currently the most effective CO2 capture technology, are the widely used elimination measures. One of the most important factors for efficient desulphurization in such methods is the choice of sorbent. As absorption capacity, desulphurization efficiency, and amount of by-products etc. are considered, ammonia is a better absorbent compared with ethanolamine. Therefore, method using ammonia as absorbent is an important method to be developed and has a good application prospect. The absorption capacity of ammonia for carbon dioxide is an important index. In this study a simple carbon dioxide absorption device using ammonia as absorbent has been designed and a volumetric analysis method has been established. The device is composed of simple units easily available. The measurement, with good compatibility and reliability, is simple and convenient, and it is safe in operation.
