Adsorber system to replace water column in a polyester process |
abstract |
The present invention provides a process for recovering a dihydroxy compound from a fluid stream that results from the preparation of a polyester by use of an adsorption system to selectively recover the dihydroxy compound. A process for recovering a dihydroxy compound from a fluid stream that results from the preparation of a polyester comprising the steps of: (a) providing a reactor having an internal volume wherein at least a portion of the internal volume is occupied by a reaction mixture comprising at least one dicarboxylic acid or ester thereof and at least one dihydroxy compound; (b) esterifying or transesterifying the at least one dicarboxylic acid or ester thereof with the at least one dihydroxy compound in the reactor to thereby produce: (i) an esterification product or transesterification product; and (ii) a fluid stream comprising the at least one dihydroxy compound; and (c) subjecting the fluid stream resulting from the esterification or transesterification reaction of step (b) to an adsorption system to selectively recover the dihydroxy compound. |
