Abstract

A steady-state process for the recovery of soluble protein from an aqueous protein-containing feed fluid is provided. The process comprises the steps of: i) passing protein capture particles in a flow countercurrent to the feed fluid in an adsorber at steady state pH to yield protein-loaded particles; ii) transferring the protein-loaded particles from the adsorber into a desorber; iii) passing said protein-loaded particles in a flow countercurrent to a protein recovery eluent in the desorber to desorb said protein from said particles at steady state pH to provide protein-free particles; iv) collecting the desorbed protein from the desorber; v) transporting the protein-free particles to a regenerator, and regenerating the particles; and vi) feeding the regenerated particles into the adsorber for use to repeat steps i)-v) in a continuous manner. An apparatus useful to conduct the steady-state process is also provided.

Abstract

A novel apparatus for an ion exchange system is provided. The apparatus comprises a first column for housing a first fluidized bed through which particles are flowed countercurrently to an ion-containing fluid to yield ion-loaded particles, a second column through which the ion-loaded particles are flowed countercurrently to an eluent fluid to yield regenerated particles, and a transport section which transfers the regenerated particles for re-introduction into the first column to repeat the ion exchange cycle in a continuous manner. A continuous method of ion exchange is also provided.
