Abstract

L’invention concerne un Procédé de gazéification en eau supercritique d’un co-digestat, le procédé comprenant :- l’injection du co-digestat, à une température T2 dans un réacteur de gazéification en eau supercritique (10),- l’écoulement, en sortie du réacteur, d’un flux supercritique (FS) comprenant de l’eau et les espèces gazeuses, le chauffage du réacteur étant assuré par la circulation d’un flux d’air chaud (FAC), fourni par une chaudière, entrant dans un circuit de chauffage du réacteur à une température T5 et ressortant de circuit de chauffage par une conduite de sortie (21S) à une température T6, le procédé étant caractérisé en ce que le flux d’air chaud (FAC) à la température T6 s’écoule de la conduite de sortie (21S) vers un premier échangeur (30) de chaleur dans lequel un préchauffage d’un flux d’air, destiné à être chauffé par la chaudière, est exécuté par échange thermique entre le flux d’air chaud (FAC) et le flux d’air. Figure pour l’abrégé : figure 1 .The invention relates to a method for supercritical water gasification of a co-digestate, the method comprising:- injecting the co-digestate, at a temperature T2 into a supercritical water gasification reactor (10),- flow, at the outlet of the reactor, of a supercritical flow (FS) comprising water and the gaseous species, the heating of the reactor being ensured by the circulation of a flow of hot air (FAC), supplied by a boiler , entering a heating circuit of the reactor at a temperature T5 and leaving the heating circuit via an outlet pipe (21S) at a temperature T6, the method being characterized in that the flow of hot air (FAC) at the temperature T6 flows from the outlet pipe (21S) to a first heat exchanger (30) in which preheating of an air flow, intended to be heated by the boiler, is carried out by heat exchange between the flow hot air flow (FAC) and airflow.
