20110927 Traxxys – Henk Akse – “Continuous Crystallization with Ni-Tech OBFC technology”

Traxxys is an SME, focusing on sustainability in process industry with specialization in Process Intensification (PI). Traxxys presents the NL GUTS Technoproject with the Ni-Tech Oscillating Baffled Flow Crystallization technology from Scotland. This continuous OBFC process features a tubular reactor with a large number of O-shaped baffles, through which the crystallizing liquid flows. On this flow an oscillation is superimposed, leading to forward and backward moving of that flow. Over the length of the tube temperature regimes can be controlled, residence times between baffles changed and energy input varied. This results in a narrower particle size distribution, better controlled crystals, a much smaller reactor and increased production capacity. The results with Purac, Croda and Cosun were presented.

There are commercial installations in pharmaceutical and specialty chemicals industry. www.nitechsolutions.co.uk www.traxxys.nl
