PROCESS AND APPARATUS FOR FORCED CIRCULATION EVAPORATIVE CRYSTALLIZATION WITH LARGE DEPOSIT INVENTORY

摘要

Disclosed are processes and apparatuses for producing a crystalline product. The processes and apparatuses may extend the operational time of an evaporative crystallizer by providing an internal volume or large deposit inventory for fouling deposits to reside without impacting the unit operation.
