Title (EN) METHOD AND INSTALLATION FOR THE CONTINUOUS HYDROLYSIS OF A VEGETAL BIOLOGICAL SUBSTANCE BASED ON CELLULOSE FOR PRODUCING SUGAR
(FR) PROCEDE ET INSTALLATION D"HYDROLYSE EN CONTINU D"UNE SUBSTANCE BIOLOGIQUE VEGETALE A BASE DE CELLULOSE POUR LA PRODUCTION DE SUCRE
Abstract: front page image
(EN)Method and installation for the continuous acid hydrolysis of a vegetal biological substance for the production of sugar for fermentation of alcohol. The problem relates to the technical and economical execution of the chemical aspect of the known method. There is proposed to use a boiler (11) with horizontal pipes from the cellulose industry, wherein material fragmented by means of an endless screw is continuously supplied. In an appropriate form of implementation, the counter current separation of the hydrolysate is effected in a first stage of a helical separator (13) constantly under pressure with the boiler (11), said separator acting also as a discharge device for the boiler. After the expension (16), a washing of the hydrolysate is carried out in a double filter press (93). At the outlet of the boiler (11) a neutralisation (114) of the acid hydrolysate is already effected.
(FR)Procede et installation d"hydrolyse acide en continu d"une substance biologique vegetale pour la production de sucre pour la fermentation de l"alcool. Le probleme concerne l"execution technique et economique de l"aspect chimique du procede connu. On propose l"utilisation d"une chaudiere (11) a tubes horizontaux provenant de l"industrie de la cellulose, dans laquelle on introduit, de facon continue, la substance fragmentee au moyen d"une vis sans fin. Dans une forme d"execution avantageuse, la separation de l"hydrolysat a contre-courant s"effectue dans un premier etage d"un separateur helicoidal (13) situe en permanence sous pression avec la chaudiere (11), ce separateur servant egalement de dispositif d"evacuation de la chaudiere. Apres la detente (16) a lieu un lavage de l"hydrolysat dans une presse a double filtre (93). A la sortie de la chaudiere (11) deja on entreprend une neutralisation (114) de l"hydrolysat acide.
