Title
(EN) MITIGATION OF FOULING IN HYDROFORMYLATION PROCESSES BY WATER ADDITION
(FR) ATTÉNUATION DU COLMATAGE DANS DES PROCÉDÉS D'HYDROFORMYLATION PAR ADDITION D'EAU
Abstract
(EN)
The extraction process for removing metal salts from an organic hydroformylation reaction fluid ("HRF") prior to returning the HRF to a reaction zone of a hydroformylation process, the extraction process comprising the step of contacting the HRF with an aqueous buffer solution, is improved by contacting the HRF with water in addition to that present in the aqueous buffer solution, i.e., with added water.
(FR)
L'invention concerne un procédé d'extraction visant à retirer des sels métalliques d'un fluide de réaction d'hydroformylation ("FRH") organique avant de renvoyer le FRH dans une zone de réaction d'un procédé d'hydroformylation, le procédé d'extraction comprenant l'étape consistant à mettre en contact le FRH avec une solution aqueuse de tampon étant amélioré par la mise en contact du FRH avec de l'eau en plus de celle présente dans la solution aqueuse de tampon, c'est-à-dire avec de l'eau ajoutée.
