| 中文摘要: |
| 用聚醚砜超滤膜分离菜籽油/乙醇混合物,研究了混合物中菜籽油质量分数(20%～60%)、操作压力(0.15～0.3 MPa)和时间(10～60 min)等参数对分离效果的影响,并探讨了该膜渗透通量的数学模型.结果表明:膜的渗透通量随着操作压力的升高而升高,随时间的延长和混合物中菜籽油质量分数的提高而降低;膜对油脂的截留率随着操作压力的升高、混合物中菜籽油质量分数的提高而降低.当操作压力为0.15 MPa、菜籽油/乙醇混合物质量分数为20%时,得到最高的油脂截留率为95.03%. |
| 英文摘要: |
| Solvent recovery from rapeseed oil/alcohol mixture with polyethersulfone ultrafiltration membranes was studied.The effects of pressure(0.15-0.3 MPa),mass fraction of rapeseed oil in the mixture(20%-60%) and operation time(10-60 min) on permeate flux and oil retention were evaluated.In addition,the mechanism of permeate flux were investigated.The results showed that increasing pressure resulted in a higher permeate flux,while the oil retention decreased;permeate flux and oil retention decreased with the incr... |
