| 摘 要： | 采用三组分溶剂对胜利柴油馏分进行了溶剂脱酸精制研究，考察了精制过程的最佳工艺条件．在剂油比为０．２５～０．３∶１、常压、温度为３０～５０℃的条件下，可将酸度小于１２０ｍｇＫＯＨ／１００ｍＬ的柴油，降至５ｍｇＫＯＨ／１００ｍＬ以下，达到优等品标准，且不影响馏分组成和闪点．萃取液在蒸发前可直接使用３～４次再去蒸发．直接回收得到的环烷酸酸值达１９０ｍｇＫＯＨ／ｇ左右，纯度达９０％以上

| Abstract: | On the basis of the experimental data of VLE for petroleum fractions from Xingjiang crude oil, a special attention has been paid to using UNIFAC group contribution method for VLE prediction with three kinds of VLE model. The group composition of a pseudocomponent molecule is calculated by the normal paraffin model molecule method. It shows that the computation results can be acceptable in engineering calculations. |
