The results indicated that the use of such membrane could achieve satisfactory separation effects (condensate of high alcoholicity and rich flavoring substances was obtained, membrane-flowing rate: ethanol＞esters except ethyl lactate＞aldehyde＞other alcohol＞water), the membrane had good selectivity to ethanol and ethyl caproate had good membrane-flowing rate and membrane-passing percentage, however, ethyl lactate, aldehyde and methanol had poor mambrane-passing percentage with heavy loss during membrane-passing.

结果表明，渗透汽化膜有良好的分离性能，可得到高酒精度、香味物质富集的冷凝液；过膜速率：乙醇＞酯类＞醛类＞其他醇类＞水；膜对乙醇选择性好，己酸乙酯的过膜率及过膜速率高；乳酸乙酯、醛类及甲醇过膜率较小、损失量较大；渗透汽化膜用于白酒的香气成分分离有良好的工业应用前景。

Through a special arrangement of baffles in the stripper, the downflow back mixing of oil gases is reduced, and the influence of stripping gas on the separation efficiency is minimized. More than 99% of separation efficiency can still be achieved.

通过汽提器的特殊结构布置，减少了反应后油气的向下返混，并最大限度地降低了汽提对粗旋分离效率的影响，使引入汽提后的分离效率仍可保持在99%以上。

The testing results showed that the optimal reduction conditions are 1320℃ for 120 min and the proportional mass fractions of activated carbon powder and the additive A are 3% and 5%, respectively. The additive A accelerates the aggregation of metallic grains so as to make the enriched metallic grains easier for magnetic separation. The mass fraction of maximum nickel in ferronickel alloy and nickel recovery in the laterite-nickel ore are 8.31% and 95.44%, respectively. Metallic nickel is thus enriched.
