1) alkaline bleach liquor extraction tower
碱抽提塔
2) extraction tower
抽提塔
1.
Application of HS-1 regular packing in extraction tower of liquid hydrocarbon;
HS-1型规整填料在液态烃抽提塔中的应用
3) alkaline extraction
碱抽提
1.
The results showed that little xylan absorbed on fiber or carbohydrate linked to cellulose was removed out during xylanase pretreatment stage and these carbohydrate mainly were removed out during alkaline extraction stage, and this would lead to an obvious decrease in special absorption coefficient.
结果表明,木聚糖酶处理过程很少脱除吸附在纤维表面或是联接在纤维表面的碳水化合物,而在碱抽提过程中,这些与木聚糖酶的反应产物才真正脱离,光吸收系数也有明显降低。
2.

结果表明:木聚糖酶结合螯合处理和碱抽提可以有效改善NaOH-AQ麦草浆HD漂白效果,同时还可以降低HD漂白废液的CODCr,减少漂白污染。
4) caustic extraction
碱液抽提
1.
Mercaptans in the light fractions of FCC naphtha from different refineries were removed by caustic extraction.
采用碱液抽提的方式,对来自不同炼油厂的催化裂化汽油轻馏分进行了脱硫醇精制试验。
2.
The trimethylsilyl(TMS) derivatives of phenolic compounds,concentrated from the oil through high efficiency caustic extraction method,were prepared by reacting quantitatively with derivative reagent.
使用高效碱液抽提法富集煤液化油中酚类组分,并使用衍生化试剂与该组分定量反应,得到挥发性大幅提高、化合物间分离程度显著改善、适于定性定量分析的酚类硅醚化衍生物。
