摘要
介绍了含四氟乙烯的不凝性尾气中,对四氟乙烯采用一种不含CFC-113的复合溶剂回收方法。以前四氟乙烯尾气回收工艺普遍采用CFC-113作为溶剂对四氟乙烯进行回收,但由于CFC-113为淘汰使用的溶剂,必须寻求新的溶剂对该尾气进行处理。实验发现,新型的复合溶剂对四氟乙烯具有良好的溶解选择性,采用该溶剂对含四氟乙烯的尾气进行回收,四氟乙烯回收率大于90%,纯度大于96%。
Introduces the recovery methods of tetrafluoroethylene （rIFE） in non-condensable tail gases with TFE by using a composite solvent without CFC-113. The TFE was generally recovered by CFC-113 as a solvent in former recovery processes of the tail gases. Because CFC-113 was a restricted solvent, new solvents must be sought out for treating the tail gases. By means of tests, it was found that the new composite solvent had the excellent dissolving selectivity to TFE. The solvent being used for recovering TFE from the tail gases, the recovery rates of TFE was more than 90% and the purity of TFE was more than 96%.
