<p>PROBLEM TO BE SOLVED: To make reaction rate sufficiently large and to miniaturize a desulfurization tower and a regeneration tower by performing both sulfurization reaction and regeneration reaction by gas-liquid reaction. SOLUTION: The dry desulfurization device is equipped with a spray device 7 of molten salt, in which at least a part of salt is melted to produce molten salt and this molten salt is mixed into a crude gas, and with a desulfurization chamber 2 in which molten salt and crude gas are introduced and brought into contact with each other and at least a part of molten salt is allowed to react with sulfur-containing gas in crude gas and a compound containing sulfur is produced and sulfur content in crude gas is removed. Since desulfurization reaction and gas-liquid reaction are performed, its reaction rate is made sufficiently large and as a result, the device is miniaturized.</p> |
