HYDROGENATION SYSTEM FOR AROMATIC COMPOUND, HYDROGEN STORAGE AND TRANSPORTATION SYSTEM EQUIPPED WITH SAME, AND PROCESS FOR HYDROGENATION OF AROMATIC COMPOUND

摘要

The energy is minimized that is required to lower the concentration of thehighboiling point components (containing the poisoning substance for thedehydrogenationcatalyst) contained in the hydrogenated aromatic compound produced by thehydrogenation of an aromatic compound. The hydrogenation system (2) for anaromaticcompound comprises a hydrogenation reaction unit (11) for adding hydrogen toanaromatic compound by a hydrogenation reaction to produce a hydrogenatedaromaticcompound, a first separation unit (12) for separating a gas and a liquidcomponent froma product of the hydrogenation reaction unit while maintaining a temperatureof theproduct generally higher than a boiling point of the hydrogenated aromaticcompound,and a second separation unit (13) for separating the hydrogenated aromaticcompoundfrom the gas component separated by the first separation unit.
