| titleOfInvention | Operation method of sulfur recovery equipment |
| abstract | A method of operating a sulfur recovery device capable of sufficiently reducing the amount of air pollutants discharged to the atmosphere while sufficiently reducing the residual amount of iron sulfide in the sulfur recovery device during a shutdown operation of the sulfur recovery device. provide. SOLUTION: A sulfur recovery unit 10 including a reaction furnace 12 that burns H 2 S to generate SO 2 , a first reactor 14 that reacts SO 2 and H 2 S to generate sulfur, and sulfur. Sulfur recovery comprising a second reactor 34 for hydrogenating SO 2 generated in the recovery unit 10 and a gas absorption unit 20 including an absorption tower 38 for absorbing H 2 S generated by the hydrogenation reaction in an absorption liquid. When the operation of the apparatus 1 is stopped, H 2 and air are supplied to the reaction furnace 12 at an air / fuel ratio exceeding the stoichiometric air / fuel ratio, and O 2 of the first reactor 14 is maintained at 0 to 1% by volume, while the sulfur recovery unit 10 has a step of burning iron sulfide adhering to the inside, and a step of reducing SO 2 generated in the step by the second reactor 34 and absorbing H 2 S by an absorbing solution.
