| titleOfInvention | Sulfur recovery method from natural gas |
| abstract | (57) Abstract: To provide a method capable of recovering sulfur from an acidic gas obtained by separating natural gas at a high sulfur recovery rate even when the natural gas contains a large amount of carbon dioxide. The method of the present invention is a method for recovering sulfur by a Claus method from natural gas containing a sulfur compound such as hydrogen sulfide and a large amount of carbon dioxide. The present method comprises a step of absorbing and separating carbon dioxide from natural gas together with a sulfur compound such as hydrogen sulfide using a chemical-physical solvent, and an acid gas obtained by the step of separating the acid gas in a volume ratio of 1 / 3 to 2/3 acidic gas is fed into the combustion reactor to produce a first gas containing sulfur dioxide, and the remainder of the acidic gas is an amine solvent with high selective absorption for hydrogen sulfide. Hydrogen sulfide concentration step for obtaining a second gas having a high concentration of hydrogen sulfide, a first gas obtained by the oxidation step, and a second gas obtained by the hydrogen sulfide concentration step And a reaction step of producing sulfur from the gas. |
