Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sulfur recovery apparatus and a sulfur recovery method each capable of recovering, in energy-saving manners, sulfur from hydrogen sulfide based on a Claus reaction.SOLUTION: The provided apparatus includes: a first hydrate decomposition unit for decomposing and then re-gasifying a gas hydrate following the reception thereof; a sulfur recovery unit for generating and recovering sulfur based on a Claus reaction using a hydrogen sulfide-containing gas as a raw ingredient; and a first heat exchanging unit for executing a heat exchange of a heat needed for re-gasifying the gas hydrate within the first hydrate decomposition unit and a cold needed by at least a portion of the sulfur recovery unit.
