摘要:: 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。
Abstract: 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 ofthe methyl ethyl ketone plant. After dehydration, the water content in the by-products can be controlled below 1%. The dehydratedby-products are oxygen-containing compounds with a relatively high octane number (the octane number reaches 106.5). Accordingto the laboratory evaluation, the dehydrated by-products can be miscible with gasoline in any proportion without stratification. Theycan be used as high-octane components to blend gasoline, thus increasing the added value of the by-products.
