Patent ID: 10793433

Abstract:
A process for manufacturing hydrogen peroxide by an anthraquinone autoxidation process (AO-process) comprising two alternate (essential) steps of: (a) hydrogenation of a working solution in a hydrogenation unit in the presence of a catalyst, wherein such working solution contains at least one alkylanthraquinone dissolved in at least one organic solvent, to obtain at least one corresponding alkylanthrahydroquinone compound; and (b) oxidation of the at least one alkylanthrahydroquinone compound to obtain hydrogen peroxide in an oxidation unit; and further comprising the step of: (c) extracting the hydrogen peroxide formed in the oxidation step in an extraction unit, wherein the units of step (a) to (c), optionally together with further ancillary units as appropriate, constitute a hydrogen peroxide production site, wherein one or more of said units are equipped with one or more sensors for monitoring one or more AO-process parameters at the hydrogen peroxide production site, said sensors being interconnected with one or more first computers at the hydrogen peroxide production site, said first computers being linked via a communication network to one or more second computers in a control room being remote from the hydrogen peroxide production site, and said control room being remotely controlling such hydrogen peroxide production site.
