Partner 9: Separex, France (SME)


SEPAREX is a SME specialized in supercritical fluid technology. As leader in the field, SEP is the sole company to offer both R&D services (Process development), toll manufacture and equipment design and construction. SEP proposes a wide range of R&D services for most applications of supercritical fluids and has been working with many companies ranging from SMEs to multinational firms involved in pharmaceutical and nutraceutical, food and cosmetics, microelectronic and innovative materials industries. Recently, SEP has been more and more involved in applications related to Material Sciences, essentially for particle design for drug formulation, ceramics, metal powders, for nanostructured materials as catalysts and aerogels, made from both organic (including polymers) and inorganic compounds. Operating several pilot plants of various sizes, SEP proposes R&D services from lab to pilot-scale leading to representative samples for market testing and data for scale-up (technical and economic evaluation). Moreover, SEP has already built more than 240 tailor-made installations perfectly adapted to client’s needs, ranging from bench-scale to semi-industrial pilot and production units (including some operated in compliance with GMP), with the support of a constant R&D effort to improve the equipment.


Previous relevant experience related to the project’s aims:

SEPAREX has been working for several years in Material Science and, in special, in Aerogel research. A part of owning several patents concerning organic gel synthesis and supercritical drying process, SEPAREX has an unique experience in building equipment for aerogel drying for both supercritical CO2 drying and supercritical Ethanol drying. Equipment have been designed and built from lab-scale to semi-industrial scale.

In the last years, SEPAREX has focused its research in the development of new drying routes in order to reduce the high procedure cost derived of the required long time of drying. The results will allow to manufacture the aerogels-like materials at a cost that can compete with the related commercial materials.


For the present project, SEPAREX will be in charge of the manufacturing of aerogels in granular and powder shape for its integration in the project solutions. Following the specifications required, the aerogels to be produced will have a size less than 2 mm of main diameter and the main properties will be a low thermal conductivity (λ<0.020Wm-1K-1), hydrophobicity and chemical stability.
