摘要：采用纳滤膜考察了操作压力、不同的料液浓度、流量改变和浓缩过程对两性表面活性剂N,N-二甲基十二烷基甜菜碱(BS-12)中盐的脱除和BS-12浓缩效果的影响。实验结果表明:在操作压力2.5 M Pa和料液流量为583 L/h下,对30%BS-12稀释后的BS-12浓度144 g/L和氯化钠浓度39.2 g/L料液进行纳滤膜脱盐浓缩,BS-12的截留率达到95%以上,氯化钠除盐率90%以上,可获得含盐量低于1%的BS-12,因而具有实际应用价值。
The effects of operating pressure, feed concentration of ampho-alkyl dimethyl betaine （BS- 12）, flow, concentration process on removal efficiency of sodium chloride and concentration efficiency of BS-12 using nanofiltration membrane were investigated. The experimental results show that BS-12 feed solution might be concentrated by nanofiltration, as surfactant BS-12 retention is more than 95% and removal ratio of sodium chloride is over 90% under the condition of BS-12 concentration 144 g/L, sodium chloride concentration 39.2 g/L, operation pressure 2.5 MPa and feed flow 583 L/h. Therefore, it might purify BS-12 product and has the practical value for production of BS-12 containing less than 1% sodium chloride.
