METHOD AND APPARATUS FOR REMOVING SOLUTE FROM A SOLID SOLUTE-BEARING PRODUCT

摘要

The process and apparatus are for removing a solute from a solute-bearing solid product by means of a solvent which remains in liquid state throughout the entire extraction vessel conducted in extraction chamber (24). The solvent and solute are collected as a miscella in vessel 42 and then separated from each other in a separation vessel (48). Temperatures and pressures are maintained so as to maintain the solvent in liquid state in both extraction chamber (24) and separation vessel (48).
