<p num="1"><br/><br/><br/> HIGH EFFICIENCY COLUMN CRYSTALLIZER<br/> ABSTRACT<br/>An improved countercurrent solid-liquid<br/>contacting apparatus, and more particularly an improved<br/>counter-current crystallizer column is disclosed. The<br/>present invention embraces the discovery that column<br/>efficiency and product purity can be substantially<br/>enhanced by reducing axial liquid back-mixing by using<br/>stationary solid beds and transport means at spaced<br/>intervals along the column length.<br/><br/> |
