20131203 TechnoForce – Mr. Raosaheb Patil - Study of supersaturation and energy dissipation fields for improved crystallizer design

TechnoForce is a 23 years SME in India of 130 personnel with an office and pilot facility at Chemelot. The facility has several pilot units for distillation, evaporation, drying and fractionation on basis of different technologies.

One of their developments is a tube plug flow crystallizer. This tube plug flow crystallizer was developed by CFD analysis of existing evaporative, cooling and vacuum crystallizer technologies, supported by lab experiments. This CFD analysis revealed that uniformity in mixing energy, uniformity in super-saturation, controlled primary nucleation, minimum attrition, minimum secondary nucleation and uniform time for crystal growth are compromised in current commercial crystallisers.

In comparative tests in The Netherlands, the Technoforce tube crystalliser with specific internals is near plug flow and features more uniform crystals and larger capacities. www.technoforce.net
