HYDROGENATION SYSTEM OF AROMATIC COMPOUND, HYDROGEN STORAGE/TRANSPORTATION SYSTEM INCLUDING THE SAME, AND HYDROGENATION METHOD OF AROMATIC COMPOUND

摘要

PROBLEM TO BE SOLVED: To suppress energy necessary to reduce the concentration of high-boiling-point components (including substances to poison a dehydrogenation catalyst) contained in a hydrogenated aromatic compound produced by hydrogenation of an aromatic compound.SOLUTION: A hydrogenation system 2 of an aromatic compound comprises a hydrogenation reactor 11 for producing a hydrogenated aromatic compound by adding hydrogen to an aromatic compound in a hydrogenation reaction, a first separator 12 for subjecting products of the hydrogenation reactor to gas liquid separation while keeping the products at the boiling point or higher of the hydrogenated aromatic compound, and a second separator 13 for separating the hydrogenated aromatic compound contained in a gas separated in the first separator.
