A Study on Protein Concentration by Foam Fractionation

以泡沬分離技術濃縮蛋白質研究

摘要


本文研究以泡沫分離技術濃縮牛血清蛋白及各項操作變因(如進料濃度、泡沫管高度、氣體流速)對濃縮比之影響,同時以工程觀點推導一簡單模式,迴歸實驗中諸多操作變因對濃縮比之影響,結果顯示此一簡單模式可有效迴歸各操作變因。

In order to develop and model an efficient continuous separation process based on foam fractionation, bovine serum albumin (BSA) solution was experimentally investigated for the effect of operation parameters (feed concentration, foam sampling height, and superficial gas velocity) on separation ration (SR). Then, an engineering approach was taken to describe this separation scheme, resulting in a design factor(ξ)which is strongly related to foam structure. A fairly good correlation between this design factor and the operating parameters, based on the nonlinear regression analysis with experimental data, was obtained.
