Title (EN) PROCEDURE FOR PRODUCING URONIC ACID BLOCKS FROM ALGINATE
(FR) PROCEDE POUR REDUIRE LA CHUTE DE PRESSION DANS UN TUYAU OU UN PIPELINE TRANSPORTANT UN LIQUIDE
Abstract:
(EN) A new procedure for producing block fractions from alginate, mainly G block alginate or M block alginate, by selective fractionated release of the M block fraction from the solid phase. MG block fractions can also be isolated.
(FR) L'invention concerne un procédé pour contrôler la chute de pression lors du transport d'un liquide à travers un pipeline (1); le procédé consiste à réguler la concentration de charge électrique dans le liquide et/ou le pipeline. Selon l'invention, le liquide est acheminé avec une charge électrique depuis au moins une électrode (2, 3), disposée dans le pipeline (1). Au moins une paroi interne du pipeline est faite d'un matériau capable d'absorber une charge du liquide et à retenir cette charge, grâce à quoi la valeur des charges similaires dans la paroi du pipeline (1) et le liquide augmente, ce qui crée des forces électriques de répulsion entre le liquide et les parois du tuyau. Cela permet de réduire le frottement entre la paroi du tuyau et le liquide.
