摘　　要：通过对甲乙酮副产物性质分析及主要有机分子模拟计算,选择汽化渗透膜分离技术脱除甲乙酮装置副产物的水,脱水后副产物中水含量能控制在1%以下。脱水后的副产物为含氧化合物,具有较高的辛烷值(辛烷值达106.5),经实验室评价,脱水后副产物与汽油可以任意比互溶,无分层,可以作为高辛烷值组份调和汽油,提高副产物的附加值。Through the analysis of the properties of by-products from methyl ethyl ketone and the simulation calculation of major or⁃ganic molecules,the vapor permeation membrane separation technology was selected to remove the water from the by-products of the methyl ethyl ketone plant.After dehydration,the water content in the by-products can be controlled below 1%.The dehydrated by-products are oxygen-containing compounds with a relatively high octane number(the octane number reaches 106.5).According to the laboratory evaluation,the dehydrated by-products can be miscible with gasoline in any proportion without stratification.They can be used as high-octane components to blend gasoline,thus increasing the added value of the by-products.
