摘要
介绍润滑油精制时苯酚中加入乙二醇的溶剂精制效果，考察了乙二醇加入量、水含量和溶剂比等因素对精制油收率和质量的影响。结果表明，在保证精制油质量前提下可使苯酚精制油收率提高２．３ 个百分点。此工艺简单易行，可望提高经济效益。
The result of phenol extraction with ethylene glycol for lube oil refining was presented. The effects of ethylene glycol dosage, water addition and the ratio of solvent to oil, etc. on the yield and quality of the refined oil were investigated. The test result showed that the yield of the qualified refined oil was increased by 2.3%. The process is simple and the economic benefit is expected to increase.
