摘要
应用均匀设计法制定N-甲基-2吡咯烷酮(NMP)精制伊朗润滑油馏分的试验方案,并对试验结果进行回归处理,建立NMP精制润滑油的数学模型并用试验验证,验证结果表明,模型的预测值与试验值吻合较好。优化模型得出了NMP精制伊朗润滑油馏分的最佳工艺操作条件:NMP中水体积分数0.34％(接近纯NMP),溶剂质量比1.62,抽提温度65.3℃。
A test scheme for Iran lube stock solvent refining by use of N-methyl-2-pyrrolidone (NMP) has been determined through the uniform design. The test result has been treated by regression, and the mathematical model has been established and verified by test. The result shows that the forecasts well correspond with the test results. The optimal operations have been obtained by the model optimization: nearly pure NMP (water content is 0.34% ) , solvent mass ratio is 1 .62 and the extraction temperature is 65.3℃.
