一种D20碳氢溶剂油的回收方法
摘要：
本发明涉及一种D20碳氢溶剂油的回收方法，包括：步骤 1，将D20碳氢溶剂油废液进行氧化，分离出有机层 ；步骤 2，在150～180℃条件下，采用催化剂对分离出的有机层进行处理 ；步骤 3，步骤 2 处理后的液体用活性炭进行吸附，收集溜出的粗D20碳氢溶剂油 ；步骤4，将收集的粗D20碳氢溶剂油进行精馏，收集 5～10mmHg 压力下85～115℃的馏分。本发明实现了对D20碳氢溶剂油的回收，回收率高，回收方法简单，节省了资源。
摘要（英）：

The invention relates to a D20 hydrocarbon solvent oil recovery method, which comprises: 1, oxidizing a D20 hydrocarbon solvent oil waste liquid, and separating to obtain an organic layer; 2, at a temperature of 150-180 DEG C, treating the separated organic layer by using a catalyst; 3, adsorbing the treated liquid obtained in the step 2 with active carbon, and collecting the obtained crude D20 hydrocarbon solvent oil; and 4, rectifying the collected crude D20 hydrocarbon solvent oil, and collecting the distillate at a temperature of 85-115 DEG C under a pressure of 5-10 mmHg. According to the present invention, with the method, the recovery of the D20 hydrocarbon solvent oil is achieved, the recovery rate is high, the recovery method is simple, and the resources are saved.
