| 摘要 |
The invention concerns a plant for production of hydrogen peroxide by the autoxidation process (AO-process), the process comprising hydrogenating an anthraquinone in a working solution, oxidizing the hydrogenated anthraquinone with oxygen to form hydrogen peroxide and extracting the hydrogen peroxide from the working solution, the plant comprising at least one skid mounted module selected from the group consisting of a skid mounted module comprising at least one hydrogenator (hydrogenation reactor) to hydrogenate the anthraquinone in the working solution (hydrogenation skid 1) ; a skid mounted module comprising at least one oxidizer (oxidation reactor) to oxidize the hydrogenated anthraquinone with oxygen to form hydrogen peroxide (oxidizer skid 2) ; optionally a skid mounted module comprising at least one means to compress air (process air compressor skid 3), to feed oxygen, in particular oxygen from the air, into an oxidizer of skid 2, and in case of presence of skid 3 a further skid mounted module comprising at least one means to recover the solvent (solvent recovery unit skid 4), in particular if oxygen from the air is used to feed oxygen into an oxidizer of skid 2 ; a skid mounted module comprising at least one means to extract the hydrogen peroxide from the working solution (extraction skid 5) ; a skid mounted module (skid 6), comprising at least one means to deliver hydrogen peroxide solution to the point of use and/or optionally to a storage tank optionally with additional means for adjusting the hydrogen peroxide concentration. Preferably the is a modular reactor system which is configured to operate without a reversion unit as a small-to-medium scale mini-AO process plant with a production capacity of hydrogen peroxide of up to 20 kilo tons per year and which can be controlled also remotely. |
