  • Patent number: 8048656
    Abstract: The invention is directed to a process for the production and recovery of chemicals, in particular hydrocarbons, from a fermentation medium, wherein solvent impregnated carriers are used. Accordingly, the invention provides a process for the production of hydrocarbon from a fermentation liquid comprising: —forming said hydrocarbon from said fermentation liquid using a biocatalyst;—contacting said fermentation liquid with a solvent impregnated porous carrier, which solvent impregnated porous carrier has a density that is different from said fermentation liquid, whereby said formed hydrocarbon is sorbed by said solvent impregnated carrier; —regenerating said solvent impregnated carrier, whereby a stream of said hydrocarbon is obtained; and optionally, recycling said regenerated solvent impregnated carrier.

  • Patent number: 7883551
    Abstract: The present invention is directed to a crystallization process and apparatuses for such processes. In a first aspect, the process of the invention comprises a step wherein a liquid comprising a solvent and material dissolved therein, is subjected to crystallization conditions in the presence of Dean vortices, which Dean vortices result from said liquid flowing through a channel having at least one curvature. In a second aspect, the invention is directed to a crystallization process, which comprises a step wherein a liquid comprising a solvent, material dissolved therein and heterogeneous particles is subjected to crystallization conditions in the presence of Dean vortices, which Dean vortices result from said liquid flowing through a channel having at least one curvature, wherein said material crystallizes on solid surfaces, in particular on surfaces of the heterogeneous particles present in the feed.
