In this research work, the three different VOCs such as acetone, dichloromethane and ethyl formate (with corresponding families like ketone, halogenated-organic, ester) are recovered by using temperature swing adsorption (TSA) process. The vapors of these selected VOCs are adsorbed on a microporous activated carbon. After adsorption step, they are regenerated under the same operating conditions by hot nitrogen regeneration. In each case of regeneration, Factorial Experimental Design (FED) tool had been used to optimize the temperature, and the superficial velocity of the nitrogen for achieving maximum regeneration efficiency (R(E)) at an optimized operating cost (OP(€)). All the experimental results of adsorption step and hot nitrogen regeneration step had been validated by the simulation model PROSIM. The average error percentage between the simulation and experiment based on the mass of adsorption of dichloromethane was 3.1%. The average error percentages between the simulations and experiments based on the mass of dichloromethane regenerated by nitrogen regeneration were 4.5%.
在这项研究工作中，使用变温吸附（TSA）工艺回收了三种不同的 VOC，如丙酮、二氯甲烷和乙酸乙酯（分别属于酮类、卤代有机物、酯类）。这些选定的 VOC 蒸气被吸附在微孔活性炭上。吸附步骤完成后，通过热氮气再生在相同的操作条件下进行再生。在每种再生情况下，都使用析因实验设计（FED）工具来优化温度和氮气的表面速度，以在优化的运营成本（OP（€））下实现最大的再生效率（R(E)）。吸附步骤和热氮气再生步骤的所有实验结果都通过 PROSIM 模拟模型进行了验证。基于二氯甲烷吸附量的模拟和实验之间的平均误差百分比为 3.1%。基于氮气再生的二氯甲烷再生量的模拟和实验之间的平均误差百分比为 4.5%。
