Title (EN) SOAPSTOCK TREATMENT
(FR) TRAITEMENT A LA PATE DE NEUTRALISATION
Abstract:
(EN) A method for the recovery of fatty acids comprising a salt of the fatty acid is disclosed. The method comprises the steps of: (a) reacting the salt of the fatty acid with CO2 and with a reagent other than hydroxide and selected from a group of compounds carrying at least one of O-H, N-H, S-H, C-O-C and C-O-N moieties, to form a reaction mixture comprising at least one of a carbonate and a bicarbonate and a product selected from fatty acids and derivatives thereof, and (b) separating the product from the reaction mixture. A method for the production of fatty acid ester from free fatty acid of crude vegetable oil is also disclosed. A free fatty acid that is substantially free of emulsifier is also disclosed.
(FR) L'invention concerne une méthode de récupération d'acides gras contenant un sel de l'acide gras. La méthode consiste à: a) mettre en réaction le sel de l'acide gras avec du CO2 et un réactif différent d'hydroxyde et sélectionné dans le groupe constitué par des composés contenant au moins O-H, N-H, S-H, C-O-C ou des fragments de C-O-N, afin de former un mélange réactionnel comprenant au moins un carbonate ou un bicarbonate et un produit sélectionné dans le groupe constitué par des acides gras et leurs dérivés; et b) séparer le produit du mélange réactionnel. L'invention concerne une méthode de production d'ester d'acide gras à partir d'un acide gras libre d'huile végétale non raffinée. L'invention concerne en outre un acide gras libre sensiblement exempt d'émulsifiant.
