SoliQz & Ultra Purification

The industrial purification of chemicals through e.g. distillation requires large amounts of energy and/or solvents. An alternative method, developed by TNO in the Netherlands, consists of melt crystallisation in combination with the Hydraulic Wash Column and delivers products with purity up to 99,9% in one step and a reduction in energy consumption from 20% up to 90% compared to distillation.

SoliQz B.V. has been established to commercialise the Hydraulic wash column for a broad range solid/liquid separation applications. This is done in close co-operation with Armstrong-Chemtec who bring their proven continuous crystallisation process and over 50 years of experience in designing and building of process equipment for the chemicals industry.

15 years of intense technology development at TNO have proven that the TNO HWC® technology delivers high purity products for a wide range of compounds at lab-scale. This performance was confirmed at the pilot scale by performing 50+ trials on the 8cm HWC column. From there onwards the technology has been successfully scaled-up to pilot and industrial scale. At SoliQz we believe there are many more opportunities in the purification of bulk chemicals, bio-based monomers and polymers as well as broad range of specialty chemicals and pharmaceutical intermediates that would strongly benefit from the implementation of melt crystallisation in combination with the Hydraulic Wash Column.
