Laws of Foam Formation and Foam Fractionation. I. The Effect of Different Operating Parameters on the Foam Fractionation of Albumin from a Solution Containing Organic and Inorganic Materials

Abstract

This study develops a continuous foam fractionation process for the separation of albumin from a dilute solution containing organic and inorganic materials. It also investigates various operating parameters such as pH, nitrogen flow rate, height of foam, height of solution, and feed position of an albumin solution. From the investigations the factors of a pH of 4.9, an N₂ rate of 10 1/hr, a feed rate of 1.8 1/hr, a solution-height of 8 cm, a foam height of 3 cm, and a feed into the solution are found optimal. A comparison of the distillation and extraction processes with foam fractionation is made on the basis of the experimental results obtained.
