Abstract:
1. A process for crystallizing a product, the process comprising: (a) crystallizing a liquid feed stream, the feed stream comprising a liquid secondary component and a liquid product component having a melting point higher than that of the liquid secondary component, in a crystallizer operating at a temperature sufficient to crystallize at least a portion of the liquid product component to form a slurry effluent comprising product component crystals and the liquid secondary component; (b) at least partially separating the product component crystals and the liquid secondary component of the slurry effluent in a filter column to form (c) converting at least a portion of the liquid secondary component of the filtrate to the liquid product component in a chemical reactor; and (d) performing at least one reslurrying process stage in series following the separation of (b), each of the least one reslurrying process stages comprising: wherein the separation unit in at least one of the least one reslurrying process stage comprises a filter column; and the separation unit in the last stage of the at least one reslurrying process stage is not a filter column.
