进行了用氮气汽提回收糠醛溶剂的实验室研究。实验结果表明 ,氮气汽提用于回收糠醛溶剂是可行的 ,汽提气用润滑油料吸收后循环使用可满足工艺要求 ;以塔底油醛含量≯ 0 .0 1 %为汽提塔的质量指标是经济合理的 ;进料温度为 2 1 0℃时 ,汽提塔的适宜操作条件为 :压力 9～ 1 1kPa ,汽提量 4%～ 5% (mol)。氮气汽提用于回收糠醛溶剂 ,具有良好的工业应用前景。 A laboratory study was conducted to recover the furfural solvent by nitrogen stripping. The experimental results show that nitrogen stripping is feasible for the recovery of furfural solvent. The stripping gas is absorbed by the lubricating oil and recycled to meet the technical requirements. The content of oleic aldehyde at the bottom of the column is 0.1% Is economically reasonable. When the feed temperature is 210 ℃, the optimum operating conditions of the stripper are: pressure 9 ~ 1 1kPa, stripping amount 4% ~ 5% (mol). Nitrogen stripping for the recovery of furfural solvent, has good prospects for industrial applications.
