A process for the production of hydrogen peroxide by the anthraquinone process, wherein the process comprises the following steps: hydrogenation of an organic working solution containing one or more anthraquinone derivatives in the presence of a heterogeneous catalyst in a hydrogenation reactor to obtain a hydrogenated organic working solution containing one or more hydrogenated anthraquinone derivatives; oxidizing the hydrogenated organic working solution obtained in step in an oxidation reactor, which is divided into an upper area, a middle area, and a lower area, by introducing the hydrogenated organic working solution obtained in step to the upper area of the oxidation reactor and an oxygen-containing gas to the lower area of the oxidation reactor to form hydrogen peroxide in a counter current process and to obtain an oxidized organic working solution containing hydrogen peroxide, wherein the middle area of the oxidation reactor is the area above the level where the oxygen-containing gas is introduced and below the level where the organic working solution is introduced into the oxidation reactor; either forwarding the oxidized organic working solution containing hydrogen peroxide obtained in step to a combined degasser/decanter equipment, or decanting the oxidized organic working solution containing hydrogen peroxide obtained in step directly in the lower area of the oxidation reactor followed by forwarding the oxidized organic working solution containing dissolved hydrogen peroxide to a degasser, for expansion of the entrained gas and degassing the oxidized organic working solution containing hydrogen peroxide; introducing the degassed oxidized organic working solution obtained in step to the lower part of an extraction column and combining it with an aqueous solution to form an aqueous phase containing hydrogen peroxide and an organic phase; removing the aqueous phase obtained in step from the lower part of the extraction column and removing the organic phase from the upper part of the extraction column and returning the organic phase back to the hydrogenation reactor; introducing at least a part of the aqueous phase removed from the extraction column in step back to the middle area of the oxidation reactor; and recovering an aqueous hydrogen peroxide solution. hydrogenation of an organic working solution containing one or more anthraquinone derivatives in the presence of a heterogeneous catalyst in a hydrogenation reactor to obtain a hydrogenated organic working solution containing one or more hydrogenated anthraquinone derivatives; oxidizing the hydrogenated organic working solution obtained in step in an oxidation reactor, which is divided into an upper area, a middle area, and a lower area, by introducing the hydrogenated organic working solution obtained in step to the upper area of the oxidation reactor and an oxygen-containing gas to the lower area of the oxidation reactor to form hydrogen peroxide in a counter current process and to obtain an oxidized organic working solution containing hydrogen peroxide, wherein the middle area of the oxidation reactor is the area above the level where the oxygen-containing gas is introduced and below the level where the organic working solution is introduced into the oxidation reactor; either forwarding the oxidized organic working solution containing hydrogen peroxide obtained in step to a combined degasser/decanter equipment, or decanting the oxidized organic working solution containing hydrogen peroxide obtained in step directly in the lower area of the oxidation reactor followed by forwarding the oxidized organic working solution containing dissolved hydrogen peroxide to a degasser, for expansion of the entrained gas and degassing the oxidized organic working solution containing hydrogen peroxide; introducing the degassed oxidized organic working solution obtained in step to the lower part of an extraction column and combining it with an aqueous solution to form an aqueous phase containing hydrogen peroxide and an organic phase; removing the aqueous phase obtained in step from the lower part of the extraction column and removing the organic phase from the upper part of the extraction column and returning the organic phase back to the hydrogenation reactor; introducing at least a part of the aqueous phase removed from the extraction column in step back to the middle area of the oxidation reactor; and recovering an aqueous hydrogen peroxide solution.
