Abstract

Plug-fow crystallization (PFC) is a promising continuous pharmaceutical crystal- lization process but is prone to fouling due to uncontrolled crystallization on the reactor surface (encrustation). This results in operational issues such as (1) fow blockage, (2) increased thermal resistance, and (3) reduced supersaturation, and in turn leads to limited continuous operation and reduced crystal quality and yield. In this work, we introduce a model-based anti-fouling control (AFC) via spatial and temporal heating and cooling cycle.
