Abstract

A novel scraped cooled wall crystallizer (SCWC-2) with 130l capacity and total heat transfer area of 2.94m²m^-3 crystallizer volume was specifically designed for eutectic freeze crystallization (EFC). It has been successfully tested for the recovery of Na₂CO₃ from an industrial solution. Compared with earlier designs this new crystallizer shows a high improvement in gravitational separation and ice scaling removal. High heat transfer fluxes between the heat exchanger and the solution (up to 10.5kWm^-2) were obtained and as a consequence high production rates were achieved.
