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

摘要

[Problem] To reduce an energy required for a treatment for decreasing the concentration of a high-boiling-point component (including a substance that is poisoned with a dehydrogenation catalyst) which is contained in a hydrogenated aromatic compound produced by the hydrogenation of an aromatic compound.[Solution] An aromatic compound hydrogenation system (2) has a constitution comprising: a hydrogenation reaction apparatus (11) for adding hydrogen to an aromatic compound through a hydrogenation reaction to produce a hydrogenated aromatic compound; a first separation apparatus (12) for carrying out the gas/liquid separation of a product in the hydrogenation reaction apparatus while keeping the product at a temperature that is equal to or higher than the approximate boiling point of the hydrogenated aromatic compound; and a second separation apparatus (13) for separating the hydrogenated aromatic compound contained in a gas that is separated by the first separation apparatus.
