本研究建立一個超重力旋轉床的模型，利用該模型來評估VOCs的吸收效率，我們根據實驗的提供操作條件進行預測，將文獻的實驗值值與模擬值比較，藉以修正我們的模型，提高模型預測的準確性。
首先進行臭氧在水中分解成氧氣的模擬，觀察超重力旋轉床對臭氧吸收情形，再添加鄰甲酚作為汙染物，觀察臭氧吸收鄰甲酚的效果，並將我們的預測值與文獻中的實驗值比對，透過修改質傳係數，使兩者的誤差率達到最小。
接著進行醋酸氣體吸收的預測，一開始使用水作為吸收液，觀察在不同轉速及氣液比下的吸收情形，並計算實驗與預測的HTU值，將兩者比較，透過修改sphericity及更換經驗式，讓HTU值的誤差達到最小。接著將吸收液更換為1wt% NaOH水溶液，運用酸鹼中和反應，提高醋酸氣體的吸收效果，並進行動態驗證，確保模型的正確性。
藉由以上的模擬驗證，證明我們的模型能夠有效的預測各種吸收情形，並可以將模型作為通用的模型，面對不同的VOCs吸收，只需更改成分與熱力學模型還有反應，再選擇適合的經驗式，就可以達到良好的預測結果。

This study develops a model of rotating packed bed (RPB) which is used to predict the absorption efficiency of VOCs. According to the operational variables provided by the experiment, we compared the experimental values with the simulated values and modified the model.
Initially, the model predicts ozone dissolution with decomposition in a RPB. We observed the absorption of ozone in RPB. Next, o-cresol was chosen as a pollutant to observe the behavior of ozonation with pollutants in RPB. Additionally, we compare our predicted value with the experiment and modify the mass transfer coefficient.
Then, The RPB model predicts the absorption of acetic acid gas using reverse osmosis (RO) water as the absorbent. Under different rotational speeds and gas to liquid ratios, we observed the absorption efficiency. After calculating the experimental and predicted HTU values, we compare them and modify the sphericity or change the mass transfer coefficient to minimize the absolute average deviation (AADs). Moreover, the RO water is replaced with 1wt% NaOH aqueous solution to improve the absorption efficiency. In addition, we used dynamic simulating to make sure our model is correct.
Through the above simulation verification, it is proved that our model can effectively predict various absorption situations, and the model can be used as a general model. In the face of different VOCs absorption, we only need to change the composition, thermodynamic model, and reaction, and then select the appropriate mass transfer model that can achieve good prediction results.
