Patent
CA 2224529
The invention is directed to a liquid phase oxidation process, wherein a first oxygen-containing gas is injected into the lower portion of a bubble column reactor vessel containing an oxidizeable organic liquid. A second oxygen-containing gas is further injected into the reactor at a point or points wherein the liquid is substantially depleted in dissolved oxygen prior to said injection. Oxygen from both the first and second oxygen-containing gases is used to oxidize the organic liquid.
L'invention porte sur un procédé d'oxydation en phase liquide, dans lequel un premier gaz contenant de l'oxygène est injecté dans la partie inférieure d'un réacteur à colonne de barbotage contenant un liquide organique oxydable. Un second gaz contenant de l'oxygène est injecté dans le réacteur en un ou plusieurs endroits où le liquide est substantiellement débarrassé d'oxygène dissous avant ladite injection. L'oxygène provenant des premier et second gaz contenant de l'oxygène est utilisé pour oxyder le liquide organique.
