Title (EN) METHOD FOR PRODUCTION OF FATTY ACIDS
(FR) PROCÉDÉ DE PRODUCTION D'ACIDES GRAS
Abstract:
(EN) A process for production fatty acids comprising: adjusting pH of a saponifiable material to a value above pH 7 by adding alkaline material; saponifying all saponifiable material by passing alternate electrical current through the material, wherein the said step of saponification occurs in a saponification reactor; acidulating the saponified material by adding acid to pH value below 4; isolating obtained free fatty acids from aqueous layer.
(FR) L'invention concerne un processus de production d'acides gras comprenant les étapes consistant à : ajuster le pH d'un matériau saponifiable à une valeur supérieure à pH 7 par ajout d'un matériau alcalin ; saponifier tout matériau saponifiable en faisant passer un courant électrique alternatif à travers le matériau, ladite étape de saponification se produisant dans un réacteur de saponification ; aciduler le matériau saponifié en ajoutant de l'acide à une valeur de pH inférieure à 4 ; isoler les acides gras libres obtenus à partir de la couche aqueuse.
