Abstract
The energy is minimized that is required to lower the concentration of the high boiling point components (containing the poisoning substance for the dehydrogenation catalyst) contained in the hydrogenated aromatic compound produced by the hydrogenation of an aromatic compound. The hydrogenation system () for an aromatic compound comprises a hydrogenation reaction unit () for adding hydrogen to an aromatic compound by a hydrogenation reaction to produce a hydrogenated aromatic compound, a first separation unit () for separating a gas and a liquid component from a product of the hydrogenation reaction unit while maintaining a temperature of the product generally higher than a boiling point of the hydrogenated aromatic compound, and a second separation unit () for separating the hydrogenated aromatic compound from the gas component separated by the first separation unit.
