Protein enrichment by foam Fractionation: Experiment and modeling
نویسندگان
چکیده
Protein flotation is a process in which protein molecules are enriched by adsorption at rising bubbles. The bubbles then form foam above the solution, where liquid drains down and dried foam, concentrated protein, extracted. Here, recovery rate purity of extract depend on stability, surface coverage, bubble size, gas flow rate, etc. In this work, we performed experiments using bovine serum albumin (BSA). addition, an unsteady state simulation was carried out numerically solving drainage equation foam. Thereby, extracted volume concentration outlet were calculated with time. Required quantities such as interface coverage or size distribution measured corresponding fed into model. showed that coalescence accelerates leading to dryer higher enrichment. modeling also reproduced tests within reasonable error range. solely relies experimental inputs does not require any tuning parameters. It can be further used for optimization up-scaling flotation.

Riser Design in Foam Fractionation
The growth of biotechnology has led to renewed interest in the possibility of enriching valuable bioproducts using foam fractionation. This is a separation process in which surface active molecules are separated from a solution by sparging through bubbles of gas. Adsorption of such molecules at the gas/liquid interface causes enrichment in the foam formed above the liquid pool. Previous work ha...
متن کاملEXPERIMENT AND APPLICATION OF AN ANNULAR FOAM BREAKER FOR FOAM DRILLING FLUID (RESEARCH NOTE)
The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. Its effectiveness in destroying drilling foam has been test in wellbore flow simulation loop experimental stand. Experimental results showed that the operating pressure of the annular foam breaker should be larger than 0.6MPa and the stabilizers concentration of the foam drilling ...
متن کاملRemoval of Mercury by Foam Fractionation Using Surfactin, a Biosurfactant
The separation of mercury ions from artificially contaminated water by the foam fractionation process using a biosurfactant (surfactin) and chemical surfactants (SDS and Tween-80) was investigated in this study. Parameters such as surfactant and mercury concentration, pH, foam volume, and digestion time were varied and their effects on the efficiency of mercury removal were investigated. The re...
