活性炭吸附-氮气脱附回收乙酸乙酯工艺研究

Technological Study on Ethyl Acetate Reclaimed from Activated Carbon Absorption-Nitrogen Gas Desorption

通过考察脱附温度、脱附风量及活性炭吸附率等因素,研究了热氮气脱附回收效果。结果表明,氮气脱附回收有机溶剂,不仅能有效解析吸附活性炭中的有机物,而且避免了水蒸汽脱附带来的各种问题,具有巨大的市场潜力。

Through the factors of desorption temperature, desorption wind-vector and activated carbon absorbance, thepaper studies the recovering effect of heat nitrogen gas desorption. The result shows that the organic solvent recovered fromnitrogen gas desorption not only can resolve the organic matters in the absorption activated carbon, but also can avoid thevarious problems brought from the water vapour desorption. It has a great market potential.
