Protein extractions with hollow fibers

Abstract

Differential protein extractions were measured with two types of extractants: inverted micelles and two‐phase aqueous systems. The results show that hollow‐fiber extractions are substantially faster than those possible in conventional equipment. The extractions are not compromised by loading or flooding because the flows of extractant and raffinate are almost completely independent. Mass transfer coefficients inferred from the measurements both support and extend design equations for these contactors.
